About:

I'm interested in the building blocks of memory, from the molecules that implement it, to the electrical signals that read/write it, to the networks that give it context. We've been building models at many scales to work on these questions. In addition to developing multiscale models of memory processes, we've also been developing the tools with which to implement these models, such as the GENESIS simulator in years gone by, and now the MOOSE simulator. We also do experiments to record brain and network activity as mice (and brain slices) learn associations.

About:

I am a Lecturer (equivalent to Assistant Professor) in the Bioengineering Department at Imperial College London, and head of the Computational Neuroscience Laboratory. 

After having studied Physics at the EPFL, I did a PhD in Wulfram Gerstner's lab, a first postdoc with Nicolas Brunel, and a second postdoctoral research fellowship in the Center for Theoretical Neuroscience at Columbia University. 

I am broadly interested in the field of neuroscience, especially insofar as it addresses the questions of learning and memory. I use mathematical and computational tools to model synaptic plasticity, and to study its functional implication in artificial neural networks.

About:

I have been teaching for more than 10 years at European CNS summer schools and was part of the last six 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 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.

About:

I was born in Madrid, but my family moved soon after and I was lucky to grow up in sunny Malaga on the Mediterranean coast of Spain. After high school, I came to the United States with a full-tuition college scholarship, and I have spent the rest of my life in different parts of this big country. I received dual BS degrees in Physics and in Computer Science from Drexel University (Philadelphia) in 1993, and a PhD in Neuroscience from The University of Texas (Houston) in 2000. My thesis work and subsequent post-doctoral studies at The University of California (San Francisco) have a common goal that continues to drive my research program today: to achieve a full mechanistic understanding of how the brain learns to control our movements with precision. Since 2008, I have been an assistant professor in the Psychology Department at The University of Pennsylvania (Philadelphia, again!). My laboratory is currently using computational approaches and tools from pharmacology, in vivo neurophysiology and optogenetics to examine how olivo-cerebellar circuits contribute to simple forms of motor learning in mice.

About:

We are at RIKEN Brain Science Institute, which locates in a greater Tokyo area. The long-term goal of my laboratory is to understand the computational principles that underlie the way neural systems realize adaptive decision-making and associated learning. Thus, my primary interest is decision-making, while my secondary interest is neural coding. Being flexible and complex, decision-making can be best understood when behavioral-level complexity and related neural systems are mapped in computational frameworks that describe and model these systems. To address these computational questions through quantitative analysis, we build computational and mathematical models and analyze behavioral, neurophysiological, and imaging data, often closely integrated with experimental investigations. More specifically, we study decision-making guided by outcomes (i.e., value-based decision-making) with two particular emphases: 1) theory (reinforcement learning, RL) and 2) social cognition (social decision-making). We are interested in decision-making whereby learning the value of an outcome via reinforcement is complemented by learning about the environment, for example, task structures under RL and others’ mental processes under social decision-making. Well, perhaps, I should stop here. Please visit our lab website http://www.itn.brain.riken.jp for those interested in more about our research and/or my background/CV. I would just like to say that I am looking forward to meeting you all in the summer school.

My research in theoretical biophysics is focused on the interface of physics and biology, broadly defined, and I explore a diverse set of problems ranging from the behavior of small organisms to the natural dynamics of human cognition.  In all of my efforts I combine cross-disciplinary experimental collaborations with ideas drawn broadly from such areas as statistical physics, dynamical systems and information theory to seek unifying principles and simple, functional understanding in living systems.  Trained in quantum gravity and early universe cosmology, as I switched focus, I was fortunate to experience a course such as this one and I hope that you will enjoy a similarly remarkable experience.

About:

I run a lab at the Australian National University in Canberra (Australia). I started out looking at muscle spindles (receptors in your muscles that detect muscle length), then worked my way up to the spinal cord, where I got my PhD looking at inhibition. For my postdoc I moved to Germany and started working in the cortex, where I developed techniques for recording from dendrites. My primary focus is on how single neurons process information, and as most of the information neurons receive is made onto their dendrites understanding the properties and function of dendrites has been something I have been interested in for a while. In the lab we use both electrophysiology (patch clamp) and imaging techniques, primarily in brain slices although I am moving more in vivo, and often combine experimental observations with modeling (mostly single cell using NEURON).

About:

Our research is in the field of Computational Neuroscience. Computer models are used to study how information is processed in the brain and how the brain circuits adapt to and learn from the environment. We employ analytical techniques from statistical physics and information theory to investigate key functional properties for neuronal circuits. We use these techniques to reduce diverse experimental findings into a few core concepts that robustly explain the phenomena of interest. We are particularly interested in activity-dependent forms of plasticity in the brain, which are known to have large impacts on learning, memory, and development. With the aid of mathematical models, we seek a theory that unites the cellular level plasticity rules and the circuit level adaptation in different brain areas and animal species. Efficacy of neurons to represent and retain information is estimated from the structure and behavior of resulting circuits.

University of Antwerp

Expertise:

Scientific interests:

I am broadly interested in the computational capabilities of individual neurons. In the field of computational neuroscience, my main interests are in the analysis of simplified neuron models using analytical and numerical tools coming from dynamical systems theory, as well as in the study of the impact of channel noise on the intrinsic properties of cells.

From an experimental point of view, my main interests concern the study of dynamical response properties of individual neurons and their capability to relay correlations delivered via simulated correlated synaptic inputs. In my experiments, I use a combination of computational and experimental techniques, based on the dynamic clamp technique: for this, I have developed an experimental toolbox that simplifies the execution of real-time closed-loop experiments. Finally, I have recently started investigating how correlations among spike trains in the mouse visual cortex are modulated by locomotion in an awake, head-fixed preparation.

Jorge F. Mejias

Affiliation

New York University

Expertise:

Scientific interests:

My main scientific interest is to understand the properties and dynamics of neural circuits, focusing on synaptic dynamics and neural heterogeneity. More precisely, I am interested in:

(i) the role of synaptic plasticity on neural networks, both short-term (http://www.ugr.es/~jmejias/files/versiones-propias/mejias09neco.pdf) and long-term (http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1003180).

(ii) the effects of heterogeneity on both small cortical circuits and large-scale brain dynamics, a topic that I have embraced in the last years (http://www.ugr.es/~jmejias/files/versiones-propias/mejias12prl.pdf).

Scientific expertise:

I have experience working with a wide range of neural network models, from Hopfield-like attractor networks to simple Wilson-Cowan rate models, and including spiking neural networks with different degrees of biological realism. Using these formalisms, I have studied electrosensory (cerebellar-like) systems, small cortical circuits displaying short-term synaptic plasticity, and more recently, large-scale brain dynamics.

Software expertise:

I usually build my own C code for heavy spiking network simulations (frequently aided by GSL and TISEAN tools), and I use Matlab/Octave for lighter simulations and when important data processing is needed. I also like to use XPPAUT for analyzing toy models and getting a better insight of the dynamics behind my models.

 

Jan Moren

Affiliation

OIST

Expertise:

I'm interested in computational neuroscience as well as in robotics. I'm originally a computer science graduate with a PhD in cognitive science, and my involvement in neuroscience comes from a desire to understand animal cognitive processes as a model for better artificial systems. My focus has been on subcortical areas, and on functions that we have in common with many other species, especially related to motivation and sensor-motor action loops. 

My thesis was on modelling the Amygdala as part of a reinforcement system. I've since worked on early attention and robot vision, and on large-scale modelling of the superior colliculus as the sensor-motor locus of an early visuomotor loop.

I'm currently part of a project at Doya-lab at OIST to understand the precise neural mechanisms that underlies tremor symptoms in Parkinson's disease. That requires us to build fairly detailed models of several areas, including the basal ganglia; the motor cortex and associated thalamic areas; brainstem and spinal interneuron systems, and a muscleloskeletal model with the local motoneuron system. As we need substantial computing power to achieve this, we use the K supercomputer, and I work at the K supercomputing center in Kobe in order to facilitate this.

Expertise: 

I am well versed in a number of subcortical areas including the amygdala and the superior colliculus, as well as, lately, the basal ganglia and related areas, although I have no experience in experimental neuroscience. I'm familiar with low-level visual systems and attention mechanisms both from a neuroscience and engineering point of view. 

I use NEST, Python (including Numpy/Scipy/matplotlib) and C/C++ on a daily or regular basis. I also use R and Octave/Matlab when the need arises, though I'm far from expert, and my previous life as a software developer means I'm familiar with a large number of other languages and software tools, and can learn new ones without much trouble.

About

I am interested in how complex motor patterns arise in animal behavior. In particular, during my PhD at the University of Buenos Aires, I worked on the brain mechanisms that give rise to the wide diversity of respiratory gestures involved in birdsong. 

My ideal way of working is in projects with a two way interaction between experiments and modeling. I love the questions that arise from nature, that inspire biophysical models, and the predictions that models imply and their aid to design experimental challenges. I am interested in designing new experiments to answer this kind of questions and bringing mathematical and physical analysis tools from the dynamical systems theory to the field of neuroscience.  

I currently have a postdoctoral position at the Dynamical Systems Laboratory at the University of Buenos Aires. I will try to understand with modeling, electrophysiological and temperature manipulation experiments, the brain architecture that is behind the coordinated motor instructions that arise in the birdsong motor pathway.

I am a graduate student working with Dr. Ernst Niebur on models of surface-based vision and attention. I am interested in the intersection of biological and computer vision and particularly why humans see so well while computers, despite the immense computational resources they have access to, still continue to "see" so poorly. Computational neuroscience gives us an opportunity to bridge these two seemingly disparate fields that have largely advanced in parallel with little to no interaction. Fundamental computational principles from neuroscience can help better inform algorithms that are able to interpret the visual world around us and use that information for behavior. Looking forward to meeting everyone in Okinawa!

About

My current research interests focus on understanding how sensory inputs from hard-wired movements such as reflexes can influence our learnt motor performance, and on using these mechanisms for the benefit of artificial motor control systems. Methods I have used involve experimental investigations spanning from electrophysiology on a cellular level to psychophysics on a behavioural level, computational modelling and simulations, as well as neuromorphic engineering. Currently I am oriented towards applications of bio-inspired sensory-motor interactions on neuromorphic motor control.

I am a Ph.D. student at physics department in IU Bloomington. I am interested in investigating brain dynamics and functional connectivity in both simulated and experimentally derived neural networks. A combination of experimental and computational approaches helps us to study the role of brain connectivity in cognition and behavior; how networks connectivity and dynamics changes under different conditions.

Not only, but very often, computational neuroscientist talk about codes, about algorithms that are implemented within some neural framework. Sure enough, these are interesting questions; relevant ones. Nonetheless, I devote most of my time trying to understand how it is possible to embed even the smallest amount of information within such a wet and dynamic structure as the brain.

Specifically, I work on developing a numeric framework which will be able to simulate the Poisson-Nernst-Planck time-dependent system for ultrastructural geometries of 3D dendritic spines segmented from EM-tomography image-stacks. The high level of details and the biophysical realism will hopefully lead to a better understanding of how the synaptic weight is tuned by biological factors (i.e. size of the spine, number of receptors, the density of cytoskeletal elements, etc).

Hi everyone! My name is Bill, currently working as a researcher at Oxford and soon to be a graduate student. My interests are broad, but I am mainly concerned with stability and plasticity in spiking neural network models, especially in the context of neuromodulation. I'm looking forward to learning new skills and having some interesting discussions at OCNC.

はじめまして!

I'm a PhD student working in the Institute of Ophthalmology, a UCL institute associated with Moorfields Eye Hospital.  My research focuses on how neural computation in the retina (as well as further upstream in the thalamus and cortex) is altered during diseases that lead to partial or total loss of vision. The Ali lab has developed several gene and cell therapies to rescue or replace the input cells that are lost or non-functional in these conditions, which gives me the unique opportunity to probe how 'visual' pathways that have never had certain kinds of visual input process this new information. 

More broadly, I am fascinated by how complex, stereotyped circuits develop from simple beginnings, and how resistant or 'plastic' they are to changes in inputs.

I am in general interested in understanding the simple(or maybe not) mathematics in the complex world of neurobiology. Of the many layers of complexity, I choose to work at the intracellular level. A number of responses can be generated from the same system depending on a number of variables like duration of the stimulus, nature of the stimulus, preexisting conditions in a neuron. My PhD research is aimed at understanding the contribution of some of these variables in generating not-so-intuitive experimentally observed result.

Presently, I am working on a math model to understand the underpinnings of spacing effect. Apart from my research I am also passionate about teaching kids and understanding how kids learn.

To be able to contribute to neurobiology so that we can someday improve how we teach kids is my biggest motivation.Looking forward to meeting you all!

The robust and species invariant emergence of orientation selectivity in the visual cortex is puzzeling. Why is orientation selectivity so common despite the enormous diversity in both, visual environments and neural circuitry? Why is its spatial organization so remarkably subtle? Together with my PhD supervisors, Walter Stühmer and Fred Wolf, I try to shed some light on the underlying mechanisms using both experimental and theoretical approaches. At the OCNC, I will analyze experimental data and (hopefully) gain some insight into the relation of natural images and the spatial organization of visual cortical orientation selectivity.

What else.. I like cookies. I studied physics. And I am looking forward to meeting you!

I am interested in understanding perception: how does our brain encodes and then decodes (i.e., perceives) the external world?

I try to study this by developing a computational model of the rodents' vibrissal system, a neural network that innervates the rodent's facial hairs (whiskers), and allows them to perceive the external environment by encoding and decoding tactile information derived from the whiskers.

Looking forward to see you all in Okinawa!

I am a research assistant at Erasmus MC and the Netherlands Institute for Neuroscience, where I work in Chris De Zeeuw's lab. The main focus on my work so far has been motor representation in the spinocerebellar system, with particular attention to the encoding afforded by the structure and electrophysiology of the Inferior Olive.

In addition to biophysical computation, my scientific interests also include mathematics and computational statistics. 

Personally, I like contemporary literature, think David Foster Wallace, 90's rock, and talking to people, so I'm excited to meet all of you!

My primary research interest is to study how sensory information is reliably and economically encoded by physiological systems. How do sensory neurons sample and process noisy input information reliably through unreliable stochastic biochemical reactions? How do they adapt continuously to better encode new stimuli? How does their structure and interconnections impact on the information encoding capabilities?

I address these questions by constructing and analysing both deterministic and stochastic computational models, which can perform as virtual neurons and replicate their input-output relationships. Depending on the particular goal, a model can be constructed with different levels of complexities, ranging from black-box mathematical descriptions to detailed compartmental structures.

The core of my PhD was to investigate the light information encoding mechanisms of fly photoreceptors. I constructed biophysically realistic fly photoreceptor models, which accurately simulate the encoding of visual information. By comparing stochastic simulations with single photoreceptor recordings, I showed how a photoreceptor uses a population of stochastically and adaptively operating units (30,000 microvilli) to sample photon information and robustly encode natural light changes.

Crucially, the population coding dynamics reduces to elementary sampling rules, which could be general in sensory neuroscience. For example, I am currently working on how spatial-temperal stochastic adaptive sampling forsters motion processing in vision systems. 

Furthermore, I am also interested in investigating the role of stochasticity in biological systems. Stochastic reactions within well-defined structural compartments in biological systems could be beneficial for them to generate reliable responses. Rather than treating stochasticity simply as noise, its merits and costs become clear when modelled and analysed within the signalling processes, for example, with Monte Carlo simulation techniques.

About

I'm a PhD student in an experimental neuroscience lab at the Hebrew University.  My research work focuses on slow processes in accessory olfactory bulb mitral cells and how they modulate information processing in the network level. Recently I started using computational tools to complement my experimental work by developing a single cell model and going back and forth between the two methods. Given that my background is purely experimental, I would like to boost my computational skills in order to make my model more efficient and expand it to the network level.
