Brief Bio/ Message

Netta Cohen is Professor of Complex Systems at the University of Leeds. She received her BSc in Applied Physics from Columbia University, and her MSc and PhD in Physics from the Technion before joining the School of Computing at the University of Leeds in the UK in 2002. A recurring theme in her research concerns the ability of biological systems to generate robust and adaptive function (often in a system that is embodied and situated in a physical environment) through the interaction between the components of the system and its environment. In this context, some of her recent work has focused on the neural control of behavior in a small roundworm called C. elegans, using a combination of experimental approaches and computational neuroscience.

Brief Bio / Message

I have been teaching for more than 15 years at European CNS summer schools and was part of the last eight OCNCs. It is always exciting to meet the diverse groups of highly motivated young scientists attending our courses. Summer courses have an important function in teaching computational methods and approaches, and in establishing social networks among the participants. Ideally every neuroscientist, including experimentalists and clinicians, should attend a CNS course because computational methods have become essential tools to understand the complex systems we are studying. There is a broad range of modeling approaches available. I have specialized in data-driven, bottom-up methods that are more accessible to experimentalists because they are mainly parameter driven. This includes large compartmental models of neurons with active dendrites, networks with realistic connectivity using conductance based neuron models and stochastic reaction-diffusion models of molecular interactions. I will not have time to present much of our research, but feel free to ask me or my collaborators about our work! Most of the work in my lab concerns the cerebellum, including its main neuron the Purkinje cell.

Brief Bio / Message

Dr. Eugene M. Izhikevich is a computational neuroscientist known for his contributions into the theory of nonlinear dynamical systems and spiking networks. He pioneered a novel approach to spiking neurons that combined biologically plausibility and implementation efficiency, which allowed him in 2005 to simulate the largest thalamo-cortical model having the size of the human brain, i.e., the same number of neurons and synapses as in human brain. Presently, Dr. Izhikevich is the Chief Executive Officer of Brain Corporation, San Diego, CA, which he founded in 2009 to build a biologically detailed spiking model of the visual system and motor control (http://www.braincorporation.com).

Before that, he was with The Neurosciences Institute in San Diego, where he founded Scholarpedia - the peer-reviewed open-access encyclopedia (http://www.scholarpedia.org). Eugene is the editor-in-chief of Encyclopedia of Computational Neuroscience and Encyclopedia of Dynamical Systems. Academic webpage is at http://www.izhikevich.org.

I studied physics at the University of Ulm, Germany. For my diploma and PhD I moved to the Max Planck Institute of Biochemistry, Martinsried, Germany, focusing on the development of novel voltage-sensitive dyes and their application in cultured neurons. To optimize voltage imaging and to use voltage-sensitive dyes with two-photon excitation I accepted a postdoctoral fellowship at the Max Planck Institute for Medical Research, Heidelberg, Germany. In my second postdoc position at Princeton University, NJ, USA, I made viral vectors delivering the gene of calcium indicators and used them for in vivo imaging in the cerebellum. Additionally, I used voltage-sensitive dyes for in vivo two-photon imaging in barrel cortex of the mouse. Since 2010 I work at OIST (Optical Neuroimaging Unit). We mainly work on in vivo voltage and calcium two-photon imaging and methods development for neuroscience.

Brief Bio / Message

Yukio NISHIMURA received his B.S. in physical education from NIHON University in 1997, his M.S. in education from Graduate school in Yokohama National University in 1998 and his Ph.D. in Neurophysiology from Graduate School for Medicine, Chiba University in 2003. He went to National Institute for Physiological Sciences, Okazaki, Japan and then the University of Washington, Seattle, USA for postdoctoral work in neuroscience. He worked as a researcher in Japan Science and Technology Agency 2009-2015. From 2011, he is currently Associate Professor in the Department of Developmental Physiology, and Associate Professor, The Graduate University for Advanced Studies [SOKENDAI] in Japan.

His overall research has concerned the neural control of limb movement in human and non-human primates. His interest in this field is motivated by its relevance to clinical issues of motor impairment and recovery of function following central nervous system damage. Abnormal patterns of muscle activation following brain and spinal cord injury contribute to weakness and loss of coordination. We still do not understand the neural mechanisms of motor deficit and of natural or therapy-induced restoration of function following lesions of the central nervous system. Our research will advance our understanding of the capacity of lesioned motor systems for neural plasticity and adaptation, and suggest ways to exploit this potential for improved function. 

Most recently, his group has developed a recurrent brain-computer interface that can record activity of cortical cells during free behavior and convert this activity in real time to stimulation of cortex, spinal cord or muscles. This so-called “artificial neural connection” creates a continuously operating artificial feedback loop that the brain can learn to incorporate into behavior. This capacitie of the recurrent brain-computer interface have promise for many basic research and clinical applications.

My research focuses on biophysical factors that affect neural coding. Trained originally as an electrophysiologist (MD, PhD McGill 2005), I went to Terry Sejnowski's lab for my post-doc to focus on computational neuroscience. I established my own lab at the University of Pittsburgh in 2008 before moving to Toronto in 2012. My lab combines in vitro electrophysiology (including a lot of dynamic clamp) with in vivo electrophysiology and optical approaches (calcium imaging and optogenetics) together with computer simulations and nonlinear dynamics. Significant research effort is directed towards deciphering the causes and consequences of differences in spike initiation dynamics. We are particularly interested in how those issues relate to somatosensory processing and neuropathic pain.

Brief Bio / Message

Since 2000, I'm running a lab at the Technion Medical School Haifa Israel. I received my PhD at the Hebrew University characterizing the single channels found in cholinergic axon terminals of the Torpedo electric fish. Later I join Sakmann's lab in Heidelberg Germany at an exciting period when dendrites were just started to be investigated with novel imaging and electrophysiological methods. I did a second post doc period with David Clapham at the US where I developed combined uncaging and imaging methods to activate and record from dendrites and spines in cortical slices. Presently I interested in nonlinear dendritic mechanisms and their potential role in information processing in-vivo. I'm also interested in differential plasticity mechanisms expressing at the different portions of the dendritic tree. In recent years we are mostly doing in-vivo two photon imaging from dendrites, and soma both in anaesthetized and awake behaving mice in an attempt to decipher the cellular mechanism underlying sensory-motor processing in the cortex.

Dear all,

In a few words, I will try to share my enthusiasm, introduce myself, my questions, and the things I like to think about. My PhD focused on the role of dendrites in single neuron computation.  I was fortunate to have Boris Gutkin as supervisor and to stumble upon a discovery during my thesis. I discovered something about dendrites -which collect inputs to a neuron- and this discovery is forcing us to alter our view on the computational capacity of a single neuron. 

I showed that, even when they are modelled as passive comparments, dendrites enable neurons to compute linearly non-separable functions (on top of the existing capacity of neurons to already compute non-linear functions like the logic AND. (Yes, I know non-linearly separable functions and non-linear functions are different sets of functions!) However, I am not yet satisfied, and many questions remain. I have a realistic outlook: neither my post-doc in London with Simon Schultz nor my future career in research will be enough to answer these questions. How does our brain store memories?  (please do not answer synaptic plasticity). Where does our creativity come from? These are two questions near to my heart.  This is maybe why I love doing science. Because I love asking questions, sometimes even more than answering them. So be aware that I will inspect your hidden assumptions and will discuss about them around machines that can distribute beer. With that being said, I am looking forward to meet you all in Okinawa,

Best,

Romain

Welcome to Okinawa everyone! I am interested in how, in many cases, we are able to respond to complex dynamics in our environments more elegantly than custom-built robotics despite typically longer transmission delays and less powerful motors (i.e. muscles). This has led me to construct detailed models of cerebellar networks in order to help understand how some of the dynamics we encounter are represented in their distinct cellular mechanisms and network structures.

Expertise

Scientific interests: 

I am interested in how the central nervous system represents and interacts with the dynamics of its environment (internal and external to the body), and in particular the role played by the cerebellum. However, in the process of building biophysically detailed models of the cerebellar network I have become heavily involved in the development of NineML (a model description language for neuroscience) and associated software tools in order to robustly manage the complexity of such models. 

 

Scientific expertise:

 - Formalising common features of neuronal/network simulations into a model description language for neuroscience (http://nineml.net) 

 - Automated reduction of large multi-compartmental models by incremental retuning with evolutionary algorithms (http://www.biomedcentral.com/1471-2202/15/S1/P178) 

 - Bayesian inference of white matter tracts from diffusion MRI using MCMC sampling methods. 

 

Software expertise:

Many areas of the brain show spatiotemporally complex dynamics. Coherent cell assembly dynamics, multiple time scale oscillations and cross-frequency phase coupling between different brain areas have been ubiquitously observed in cortex, hippocampus, the basal ganglia and the cerebellum. Their dysfunction is fundamental in many neuronal pathologies such as schizophrenia and epilepsy. Yet how these complex dynamical patterns arise and why they are necessary for normal cognitive brain function remains mysterious. My goal is to understand how brain function, in particular perception, action sequence generation, rhythm production and language emerges from the spatiotemporally chaotic dynamical activity patterns generated by the spiking networks of the brain.

I am currently a PhD student at the Centre for Cognitive Science, Indian Institute of Technology Gandhinagar. My doctoral research topic is focused on the convergence of perceptual, value based, and social decision making using behavioural and computational approaches. I study subjective valuation by investigating how an individual provided with sequentially repeated choices modulate their valuations of the available alternatives, i.e., choosing and staying with the outcome from the previous choice or switching to the other alternative. In an attempt to explain participant's choice behaviour (e.g. modulation of choices in a perceptual random dot motion task due to the effects of stimulus and choice values), I also use computational models (e.g. reinforcement learning, bayesian and drift diffusion models) to further model participants’ choices.

About yourself

/Message

I am a first year PhD student in computational neuroscience working with Thomas Wennekers at Plymouth University in England. I am interested in brain processes related to higher-order cognition such as problem solving, attention, learning and memory. To understand our cognition better, I am developing models of cognitive functions using biologically constrained neural networks. I am also interested in how and why biological neurons and their properties make us humans better (or worse) in some tasks compared to approaches in artificial intelligence. My MSc is in computational neuroscience from BCCN Berlin and BSc in computer science from University of Zagreb.

I am a first year PhD from Technical University in Berlin. I am studying cortical microcircuits. I am trying to gain a better insight on how neurons interact within the network and how through this interaction they encode information that is relevant to animal's behaviour. I am particularly interested in understanding how come populations of neurons are able to encode the information reliably while responses of single neurons are strikingly variable.

I am a PhD-student in the Computational Neuroscience group of Walter Senn at the University of Bern. My main research interests are mathematical approchaches to learning and memory. I am especially interested in how biological rules for learning with synaptic plasticity can be described by Gradient Descent algorithms, and how some these algorithms are related to internal properties of the neuron.

Looking forward to see you all soon on Okinawa!

I am a Bioengineering PhD student doing research in systems neuroscience. I am interested in understanding the role of serotonin in behavior, in particular when behavior has to be adapted to new environmental conditions. Based on experimental data I collected, I am now interested in learning about how I can model neuromodulators' role in behavior.

My research to date has focused on single neurons, and more recently, the interaction between internal brain signals and incoming sensory signals. I have a particular interest in how the interaction of ion channels supports sophisticated neural functions such as adaptation and single neuron feature selectivity, and have pursued this topic in a number of different in vitro preparations. I am currently working in the thalamocortical system, studying the effects of cortical feedback on thalamic processing of sensory signals in vivo, and how the intrinsic properties of thalamic neurons interact with the statistics of cortical and sensory input. I am specifically focused on understanding how the thalamus acts to process information, rather than simply relay signals to the cortex, and how thalamic neurons integrate and encode information from synaptic inputs from the sensory periphery and the cortex.

I'm a PhD student researching the neural mechanisms that underlie neuropsychiatric disorders. My particular interest is in developing clinically useful mathematical models that predict diagnosis and treatment in psychiatry. I'm currently running a clinical trial that combines neuroimaging (fMRI), brain stimulation, and cognitive measures in depressed patients. As a cognitive neuroscientist, I'm really excited to learn and work on computational modelling in Okinawa, and hear about everyone else's research!

I'm studying (PhD, 4th year) how dopamine modulates working memory and decision-making processes in the primate prefrontal cortex. I record single neuron data from monkeys while stimulating and blocking specific dopamine receptors. Based on that data, I hope to model dopamine functions in prefrontal network models. I have a background in biology, mathematics, and philosophy. I'm looking forward to meeting you all!

I am interested in understanding the mechanistic principles that underlie behavioral responses. To unravel the neural basis of a behaviorally relevant sensory percept, I started a PhD in September 2014 in the field of Computational Neuroanatomy. My PhD research aims to uncover how biophysical properties, and anatomically/functionally synaptic input patterns, especially inhibitory ones, encode the sensory percept of whisking during object localization in rats. I hope that my research will help to facilitate formulating rules that may be transferred to other sensory modalities. Besides my interest in understanding how the brain 'works', I am really fascinated by brain-computer interfaces.

Hello everyone! For my current PhD-research, i'm studying the neuronal dynamics underlying memory processes in the hippocampal formation. I perform large-scale extracellular recordings (using tetrodes) in freely-moving mice, combined with closed-loop optogenetic intervention. Having a background in Statistics, a large part of my studies is devoted to the analysis of the resulting complex multi-dimensional data. At OCNC i hope to get introduced to computational modelling, and in particular to learn to generate simulated hippocampal recordings.
