2/09/2016 4:00 PMHidden Hearing LossA/Prof James Fallon
Abstract: Recent animal studies have demonstrated that moderate sound exposure can damage up to half the auditory nerves and their synapses, without damaging hair cells. As only a small number of the highly sensitive low-threshold auditory nerve fibres are required for sound detection in quiet environments, there is no loss in auditory sensitivity. Normal auditory thresholds, despite the significant loss of auditory nerve fibres, has led to this type of damage being termed a ‘hidden hearing loss’. To date, the only reported functional consequence of the loss of auditory nerves and their synapses is an increase in median spontaneous firing rate of the auditory nerve fibre population. However, modelling of the loss of functional auditory nerves and their synapses is expected to result in a reduction in temporal fidelity. This project aimed to quantify temporal processing deficits using both behavioural and electrophysiological techniques in an guinea pig model of hidden hearing loss.
Bio: A/Prof James Fallon’s training, like his research interests, is multidisciplinary in nature, and is focused around the successful development and improvement of neural prostheses, with an emphasis on the role of central nervous system plasticity. He has formal training in both physiology and engineering and employs a range of techniques from basic engineering through anatomical studies to behavioural studies. He has over a decade of experience in recording from the central auditory pathway and is considered a world expert on the plastic response of the central auditory system to deafness and subsequent reactivation with a cochlear implant.
26/08/2016 4:00 PMThe expected benefit of hearing aids as a function of hearing lossProf Peter Blamey, Executive Director Operations & Technology, Blamey & Saunders Hearing Pty Ltd
Abstract: It is often reported clinically that it is important to manage the expectations of clients when fitting hearing aids, but there is little scientific information available about what is a realistic expectation and how to quantify the benefits of hearing aids.  The aim of this study was to estimate the speech perception benefits of hearing aid fitting for clients with different degrees of hearing loss.  The difference between the aided and unaided percentage correct scores on a monosyllabic word test presented binaurally was used as the measure of benefit.  Retrospective data for 592 users of the same type of hearing aid with pure-tone average hearing losses ranging from 6.5 dB HL to 78.5 dB HL in the better ear were analysed using a paired t-test and non-linear regression.  The mean benefit for this group of clients was 18.3% with a 95% confidence interval from 17.0% to 19.6% (paired t=27.1, p<0.001). On average, hearing aids halved the error rate for difficult listening tasks in quiet, and listeners can expect to reduce their error rate in running speech by a factor of four.  The benefit for this group was approximately equivalent to a 28 dB reduction in hearing loss.
Bio: Peter is a hearing scientist, inventor, and entrepreneur who has developed technology and business models that are bringing improved hearing to people throughout Australia.  Peter and his business partner, Elaine Saunders, sell premium hearing aids direct to end-users, enabling them to take control of their own hearing through their online company ( Built on a heritage of research conducted at the Bionics Institute, the company is continuing to innovate and grow, and is starting to manufacture hearing aids in Melbourne.  The company won the inaugural Social Innovation section of the Australian Good Design Awards last year.
5/08/2016 4:00 PMKinEdge: accurate human motion capture using Microsoft Kinect v2 and computer vision techniquesGino Coates & Alessandro Timmi, St Vincent's Department of Surgery, The University of Melbourne
Abstract: Three-dimensional motion analysis has made it possible to analyse different aspects of healthy and pathological human movement. However, motion capture requires expensive and cumbersome multi-camera systems, which track reflective markers attached on the subject’s skin.
The recent release of Microsoft Kinect v2, a gaming device which can track human motion without the need for markers, has generated considerable interest in the biomechanical community, especially given its low cost and portability. However, Kinect v2 marker-less tracking algorithm is highly inaccurate compared to multi-camera motion capture systems: deviations up to 20 cm make this methodology unsuitable for biomechanical or clinical analyses, where accuracy is essential for proper evaluation.
In light of this limitation, we developed an alternative real-time tracking method, based on raw RGB-D data from Kinect v2, custom-made coloured markers and computer vision techniques. Our solution, KinEdge, is one order of magnitude more accurate than the out-of-the-box Kinect v2 marker-less tracking algorithm and runs on consumer-grade PCs. KinEdge can facilitate the adoption of Kinect v2 as a low cost, portable motion tracking solution for biomechanical, rehabilitative, clinical and sports applications. This presentation will walk you through the development of our novel solution and its application for spine tracking and gait analysis.

29/07/2016 4:00 PMUsing CRISPR/Cas9 technology to identify and validate novel cell death regulators Dr Marco Herold, Laboratory Head, Molecular Genetics of Cancer Division, The Walter & Eliza Hall Institute
Abstract: CRISPR/Cas9 mediated genome engineering provides an easy and rapid way to edit genes in vitro and in vivo. Initial experimental strategies utilised proved to have a low efficiency and were not broadly applicable to all cell types. In order to overcome this hurdle and to allow for efficient modification of genes in the haematopoietic system, we have developed a novel drug-inducible lentiviral system to deliver the CRISPR/Cas9 platform to cells permitting efficient genome engineering in vitro and in vivo. Additionally we have recently also implemented the CRISPR/Cas9 technology to produce genetically modified mice and to perform whole genome screens.
Bio: Marco Herold is a Laboratory Head in the Molecular Genetics of Cancer Division at WEHI. He is an expert in developing novel mouse models of human cancer, and has brought the CRISPR/Cas9 genome editing technology to WEHI, where he has recently been appointed to the position of Head of the new Genome Editing Laboratory; the task of this laboratory is to generate mutant mice using CRISPR/Cas9 methodology.

His major research interest is in the identification of novel genes in apoptosis, and in finding new targets for cancer therapy.
22/07/2016 4:00 PMIntroducing a silicone process for electrode design Frank Rehberger, Masters Student & Research Assistant, University of Freiburg, IMTEK, Laboratory for Biomedical Microtechnology
Abstract: Silicone as implant material has been used for decades. Spin processing (a technique originating in microelectronic fabrication) can be used to create thin layers of silicone with good control of process parameters. This is an established process and has been used in electrode fabrication previously. Combining this technique with other processes and integration of different materials to tailor the physical properties could create new possibilities for electrode development. Our aim was to set up the basic spin process, then modify it and combine it with available processes. To further raise the potential, we addressed the issue of structuring layer-based materials in three dimensions. The results suggest that this might be useful tools in future electrode Design.
Bio: Frank Rehberger is a student at the Department for Microsystems Engineering at the University of Freiburg. He joined the Laboratory for Biomedical Microsystems as a student assistant in 2013 to work on silicone waveguides for Optogenetics and completed his B.Sc. in 2014.

15/07/2016 4:00 PMMediolateral balance assessment using tracking tasksDr L. Eduardo Cofré Lizama, The University of Melbourne
Abstract: Falls in older adults and neurological populations have been found to be associated to incorrect weight-shifting during, for example, standing and walking. Therefore, assessment of mediolateral balance is crucial for determining subjects at risk of falling but also to determine efficacy of rehabilitation interventions. However, current clinical tools are direction unspecific, insensitive to subtle deterioration of balance and have ceiling effects. In this regards, the mediolateral balance assessment (MELBA) has been proposed. MELBA consists in tracking predictable and unpredictable visual targets with the centre of pressure (CoP) or mass (CoM) by leaning the whole body sideward. The bandwidth of accurate tracking in terms of phase-shift (delay) and gain (amplitude) are then used to quantify balance control. This tool has shown to be a reliable, valid and sensitive to subtle detriments of ML balance control. Currently MELBA is being studied in neurological populations and further implementation in clinical settings is expected.
Bio: Dr LE (Eduardo) Cofré-Lizama is a physiotherapist from Chile and MSc in Physiotherapy (UNIMELB) who graduated from the MOVE-AGE joint Doctorate program (MOVE Research Institute Amsterdam and KU Leuven) in 2014.

He is currently working at MOVElab (RMH-Royal Park) were he is working on projects related to identification of movement biomarkers of MS progression, walking patterns in amputees and neuromodulation in neurological populations.
1/07/2016 4:00 PMApplication of Literature Mining for Protein Function PredictionA/Prof Karin Verspoor
Abstract: The biomedical literature captures the most current biomedical knowledge and is a tremendously rich resource for research. With over 24 million publications currently indexed in the US National Library of Medicine’s PubMed index, however, it is becoming increasingly challenging for biomedical researchers to keep up with this literature. Automated strategies for extracting information from it are required. Large-scale processing of the literature enables direct biomedical knowledge discovery. In this presentation, I will introduce the use of text mining techniques to support analysis of biological data sets, and will specifically discuss applications in protein function and phenotype prediction, facilitated by analysis of the literature and integration with complementary structured resources.

17/06/2016 4:00 PMGene therapy for protecting and regenerating sensory cells in the cochlea after hearing loss Dr Rachael Richardson, Senior Research Fellow, Bionics Institute
Abstract: An estimated 360 million people suffer from hearing loss worldwide. Sensorineural hearing loss is characterized by permanent loss of cochlear sensory hair cells and severe degeneration of auditory neurons. The goal of the gene therapy program at the Bionics Institute, headed by Dr Rachael Richardson, is to use gene therapy to protect, repair or regenerate these sensory cells after hearing loss. The gene therapy program broadly encompasses the use of neurotrophin gene therapy for protection and regrowth of auditory neurons, Atoh1 gene therapy for the regeneration of hair cells and optogenetics to allow optical stimulation of auditory neurons. Within these research topics, major research themes have been gene therapy delivery to the cochlea, the impact of the degenerative processes of hearing loss and the effect of cochlear implantation on gene therapy. This presentation will provide an overview of our recent research on gene therapy in the cochlea for protecting and regenerating sensory cells in the cochlea after hearing loss and optogenetics in the cochlea for optical stimulation of auditory neurons.
Bio: Dr Rachael Richardson is currently a Senior Research Fellow at the Bionics Institute. Rachael’s research focus is on gene therapy in the cochlea for the preservation and regeneration of cochlear sensory cells after hearing loss. She is particularly interested in hair cell regeneration using the Atoh1 gene as this has the potential to reverse hearing loss.  She uses viral gene therapy techniques to create localized regions of gene expression in the cochlea for sensory cell survival or regeneration. Recently Rachael and her team have also been investigating optogenetics to determine whether auditory neurons can be stimulated more precisely with light compared to electrical stimulation.
Rachael receives competitive funding from the NHMRC as well as from philanthropic sources in Australia and the UK. Dr Richardson completed a BSc degree at the University of Melbourne in Biochemistry and Pathology. Her BSc(Hons) and PhD were undertaken at the Walter and Eliza Hall Institute of Medical Research, Department of Cancer and Haematology, supervised by Prof Doug Hilton. Rachael has worked at the Bionics Institute since 2001.
10/06/2016 4:00 AMWhy does speech understanding vary among adult cochlear implant (CI) recipients?Prof Colette M. McKay
Abstract: Around 30% of adult CI users have poor speech understanding, and rely upon lip-reading for communication. History factors such as duration of deafness account for only around 10% of the variability in outcomes, making poor prognosis a critical clinical issue. Different physiological mechanisms have been proposed to account for poor speech understanding, including patchy survival of peripheral spiral ganglion cells (SGCs) and plastic changes in the central auditory system or in the cortical networks that support language processing. Evidence supporting these mechanisms comes from animal studies and from EEG, imaging, or psychophysical studies in human CI users. However, so far it is unclear whether these mechanisms have independent causal effects on speech understanding, how they could be assessed before implantation, or whether they can be reversed after implantation with targeted therapies or specific signal processing strategies.
In this presentation, I will summarise recent work at the Bionics Institute in which we found strong correlations between poor speech understanding and the following measures: A) variability in thresholds of highly focussed stimuli in a research CI (evidence of patchy SGC survival) B) poor detection ability of small changes in relative current level across different electrode places and C) high activation levels in the bilateral pre-frontal cortices as measured by a novel brain imaging technique called functional near infrared spectroscopy. Finally, I will propose a model that related these measures to poor speech understanding and how the techniques might be used to improve prognosis or individually optimise hearing therapies after implantation.

3/06/2016 4:00 PMNeurogenesis and neuroprotection against retinal degenerative diseases Prof Antonia Angulo Jerez
Abstract: The retinal neurogenesis has been demonstrated in several mature mammalian retinas. Stem or progenitor cells located in the ciliary body can originate retinal neurons. Our immunohistochemistry and electron microscopy studies have shown cells expressing molecular markers of neural and retinal progenitors in the pars plana of the ciliary body of adult primates and humans. The peripheral retinal margin thus represents, in monkeys and humans, a region where cellular morphological maturation and synaptogenesis is taking place in a fashion recapitulating the normal development of retinal cells. Further knowledge on the cellular extrinsic and intrinsic factors and genes involved in adult retinogenesis in primates will prove useful toward the design of therapies targeting retinal neurodegenerative disorders.

On the other hand, proper development and functioning of the retina requires a precise balance between the processes of proliferation, differentiation and programmed cell death. The retina is one of the most susceptible tissues to reactive oxygen species damage. It has been recently shown that the efficacy of natural products to slow retinal degenerative processes through different pathways. We assess the neuroprotective effect of safranal and tauroursodeoxycholic acid (TUDCA) in an animal model of retinitis pigmentosa (P23H rats). These compounds could be potentially useful for therapeutic applications in retinal degenerative diseases.

8/04/2016 4:00 PMFeasibility of a minimally invasive Endovascular Neural Interface for recording cortical activityDr Sam John
Abstract: Intracranial electrode arrays for recording and stimulating brain activity have facilitated major advances in the treatment of neurological conditions. Traditional arrays require direct implantation into the brain via open craniotomy. Invasive surgery is associated with inflammatory tissue responses and can reduce efficacy of stimulation and sensitivity of recording. There is a need for minimally invasive techniques that can record chronic neural activity.
We demonstrate the feasibility of a minimally invasive endovascular neural interface (ENI) that can record brain activity from within a cortical vein. The ENI was fabricated on intracranial stents that are presently used in stroke clot removal. The ENI was delivered into a superficial cortical vein overlying the motor cortex using contrast enhanced angiography and co-axial catheterization in sheep.
The ENI was successfully implanted in sheep and was able to record somatosensory evoked potentials for 190 days. Impedance changes show that incorporation of the ENI into the blood vessel wall occurs within 14 days of implantation and vessel lumen remained open for the duration of the study (190 days). The bandwidth of recording, was similar to an epidural array and marginally inferior to a subdural array. We show that an endovascular neural interface offers a method for safe implantation and chronic neural recordings.
Bio: Sam John is a research fellow in the Department of Electrical and Electronic Engineering at the University of Melbourne. He received his PhD in 2013 from La Trobe University while working on the Bionic eye project at the Bionics Institute.

1/04/2016 4:00 PMExercise and physical activity for people with Parkinson's disease:  Challenges in clinical practice and research A/Prof Jennifer McGinley
Abstract: Parkinson’s disease (PD) is a common and disabling neurodegenerative condition that is rapidly rising in prevalence.  With medical advances, people with PD live an increasingly long lifespan, but experience difficulty with mobility, activities of daily living and societal participation.
Exercise limits disability progression; people who exercise regularly have lesser decline and better physical function, mobility and quality of life.  Despite these known benefits, most people with PD have sedentary lifestyles and limited adherence to ongoing exercise is a major challenge in lifelong management. 
Health behaviour change interventions can be developed to promote long term exercise and physical activity habits throughout life. Such interventions need to be guided by an understanding of factors associated with exercise and physical activity behaviour in Parkinson’s.  This seminar will present findings from a recent large study of Australians living with PD, and the factors that promote or limit ongoing engagement in a physically active lifestyle. Current challenges in conducting clinical trials of new interventions and implementation will be discussed.
Bio: Associate Professor Jenny McGinley is a physiotherapist and Deputy Head of the Physiotherapy Department, University of Melbourne, Australia.  Her research has focussed on the measurement and understanding of movement and function across the lifespan in healthy people and those with neurological conditions including Parkinson’s disease, stroke, cerebral palsy and autism.

Her current research aims to understand how people with Parkinson’s disease and other neurological disorders can stay active during daily life, and the factors that influence regular physical activity
18/03/2016 4:00 AMInsights into neuropathology using speech Dr Adam Vogel
Abstract: Speech is a potent marker of brain function. It changes with the onset of neurological illness and it declines with disease progression. Certain transient conditions such as depression and fatigue also affect the quality of speech, making it a sensitive marker of central nervous system integrity.
In this context, speech can be used to track disease progression in degenerative diseases such as Parkinson’s disease or hereditary ataxia. Similarly, objective measures of speech can assist in monitoring performance in clinical trials where changes in brain health are anticipated.
Bio: Adam is director of the Centre for Neuroscience of Speech at The University of Melbourne. His team works towards improving speech, language and swallowing function in people with progressive and acquired neurological conditions.

4/03/2016 4:00 AMEngineering better patient outcomes for visual prostheses Dr Matt Petoe
Abstract: Over the last decade, retinal prostheses ('bionic eyes') have emerged as the most promising technology to restore vision to those with blindness caused by photoreceptor loss.
In an idealised representation of artificial vision, an image captured by the head-mounted video camera is transmitted to the electrode stimulation site on the retina and perceived as a clearly defined set of pixels. The reality of artificial vision is quite different however, with patients reporting perception that is very much unlike their previous sighted experience. In spite of this, it is possible for bionic eye recipients to routinely perform tasks of orientation and mobility, as well as improve performance in activities of daily living.
This talk will discuss some of the challenges faced by bionic eye recipients and discuss ways to identify patient behaviours and tailor post-implantation rehabilitation accordingly.
Bio: Dr Matt Petoe is a biomedical engineer with a keen interest in human perception, neuroscience and clinical research. He is currently working within the Bionic Vision research team to trial the safety and efficacy of a next generation, wide-view bionic eye.
19/02/2016 4:00 PMRestoration of arm function after neurological insultProf Mary Galea,Department of Medicine (Royal Melbourne Hospital), The University of Melbourne
Abstract: Loss of hand function, as may occur after stroke or spinal cord injury, has a severe impact on day-to-day activities and a person’s independence. A vast neural network at both cortical and spinal levels is dedicated to control of hand function, and spared pathways can provide the structural basis for recovery of function after damage to a particular region.
The clinical challenges involve the questions of how to activate the remaining pathways after brain injury, and how to maximise function after spinal cord injury which interrupts the connections between the brain and spinal cord. This talk will cover the physiological basis for recovery of function as well as examples of clinical research programs investigating restoration of function after stroke and spinal cord injury.
Bio: Mary Galea is a physiotherapist and neuroscientist whose research program includes both laboratory-based and clinical projects with the overall theme of control of voluntary movement by the brain, and factors that promote recovery following nervous system damage. She has a particular interest in recovery of arm function, and is currently undertaking projects in patients with stroke, spinal cord injury and multiple sclerosis.

Abstract: Patients with combined cerebellar and vestibular impairment were first identified in 1979 and were studied as a pathophysiological model. The syndrome of Cerebellar Ataxia with Bilateral Vestibulopathy (CABV) and it’s characteristic oculomotor abnormality, that is, the abnormal visually-enhanced vestibulo-ocular reflex (VVOR) was then subsequently described in 2005 in 4 patients, 3 of whom had a peripheral sensory deficit.
This work defines a new neurological disease that is now called ‘CANVAS’: an acronym for Cerebellar Ataxia with Neuropathy and bilateral Vestibular Areflexia Syndrome. We detail the (A) clinical presentation and evolution, (B) essential oculomotor and vestibular abnormalities, (C) neuropathology, (D) otopathology, (E) anatomical pattern of cerebellar atrophy,  (F) neurophysiological characteristics of the somatosensory impairment, (G) differential diagnoses, (H) apparent genetic basis and (I) a diagnostic quantitative bedside oculomotor test.
Bio: David Szmulewicz is a Neurologist, Neuro-otologist and medical researcher. He holds a PhD from the University of Melbourne.

Flavio went on to pursue post-doctoral studies in Ophthalmology at Université de Montréal, where he became Chief of Retinal Service in the Department of Ophthalmology and serves as associate professor. In addition to instruction mandates in prestigious institutions such as Harvard Medical School and Pontifícia Universidade Católica in Rio de Janeiro, Flavio garners experience with a dozen clinical trials and research projects, and has many awards, namely 5 ASRS Rhett Buckler Awards. He has co-published well over 50 books, papers, and abstracts covering various aspects of retinal surgery. Dr. Rezende is the 1st surgeon to perform a bionic retinal implant in Quebec, and the 2nd in Canada.
29/01/2016 4:00 PMReverse Engineering the Brain: Computer Modelling of Neural CircuitsDr Dean Freestone, University of Melbourne
Abstract: This presentation is focused on methods for reverse engineering the brain. In this talk, I will discuss various approaches for constructing computer models of neural circuits using experimental and clinical data. The computer models describe data recorded at the local field potential or electroencephalogram scale, and are therefore coarse grain approximations of neural activity. I will show examples of how we can use various modelling approaches to decode the mechanisms of epileptic seizures and movement related activity from neural signals.
