IEEE RO-MAN 2016 Workshop on Neuroscience Methods in Human-Robot Interaction (New York City, 26-31st August, 2016) Neuroscience methods such as brain imaging are increasingly used to address research questions in robotics, robot-human communication and interaction. This workshop will provide an overview of state-of-the-art work at the intersection of human-robot interaction and human neuroscience, to show how cross-disciplinary collaboration can be a win-win, and to help increase communication between researchers from different yet complementary disciplines, with the hope of catalysing new ideas and collaborations. Neuroscientists with expertise in several topics of interest for RO-MAN 2016 <http://www.ro-man2016.org/> (e.g., embodiment, empathy, social cognition, body movements, gestures, facial expressions, anthropomorphism, learning and imitation, social presence, inference of human states, machine learning and brain-machine interfaces) will introduce the methods used, and present empirical work exemplifying their application to robotics, highlighting not only how such studies have led to insights on neural mechanisms of interaction, communication, and collaboration, but also how the findings inform the design and development of new robots, robot-human collaborative systems, interaction modalities and interfaces. We will solicit papers from the broader community that address these themes. Robotics and neuroscience both being active, rapidly developing, and high priority research areas, and the combination of expertise across disciplines holding great promise for advances in both theory and applications, the workshop will serve an important role by bringing together researchers coming from different backgrounds. Panel sessions will address challenges for interdisciplinary and novel research and discuss ideas for increasing synergy and impact future work. *SPEAKERS* Ayse P.

2nd Call for Papers: Extracellular Space
by Reinoud Maex 07 Mar '16

07 Mar '16

JOURNAL OF INTEGRATIVE NEUROSCIENCE http://www.worldscinet.com/jin Call for Papers! Special Issue on Extracellular Space In experimental neuroscience, most electric signals are picked up from the electrolytic (or colloidal) solution that constitutes extracellular (interneuronal) space, yet the origin of these potentials is incompletely understood. Even more, theoreticians have recently argued about the physical principles underlying these phenomena. The present special issue invites experimental and theoretical work that can shed light on electric phenomena in extracellular space, with an emphasis on extracellular potentials and endogenous electric field interactions. The contributions solicited are original research papers and comprehensive reviews on methodological aspects. Submission deadline: 30 September 2016 Contact: Dr. Reinoud Maex reinoud.maex(a)ens.fr Questions that may be addressed are (but are not limited to): 1. The nature of extracellular potentials - What is nature of the electric currents, and what is the velocity (distribution) of the ions involved? Since membrane currents underlie the extracellular currents, what are the relative contributions of synaptic versus voltage-gated channels, excitatory versus inhibitory synapses, capacitive currents? How important are Lorenz forces between currents (due to the generated magnetic fields) and is there a contribution of polarization currents? - Is extracellular space purely resistive, or is a capacitive component involved, and what factors (such as ionic concentration, Debye shielding, etc.) contribute to its resistivity? 2. Modeling of extracellular potentials and electric field interactions - What level of detail is needed to model extracellular electrical phenomena, and which formalism can be employed? How valid is the cable equation, or need slow concentration changes of the major ionic components involved be modeled explicitly? How can LFP calculations be incorporated in simulation software? - Can volume transmission be simulated adequately as volume conductors? Are ephaptic coupling effects adequately simulated in one dimension? 3. Neuronal inference from measured extracellular potentials - What is the importance of the electrode characteristics for the proper interpretation of the measured signals? - What are the underlying assumptions, and limitations, of current-source-density analysis? How valid is the dipole approximation? Why are recent experiments being interpreted in terms of monopoles, and can single-compartmental model neurons generate local field potentials at all? - What can be learned from the power density distribution of signal frequencies? 4. Neurostimulation - What is the effect on neurons of an externally applied current or potential, and what mechanism (or rationale) underlies deep brain stimulation? 5. Physiological roles of extracellular potentials and endogenous electrical fields - Do extracellular potentials contribute to neuron-neuron and neuron-glia communication? Can there be a role for extracellular potentials in the homeostasis, clearance, and volume regulation of extracellular space, and in the control of blood flow and of the blood-brain-barrier. - What is the integrative role of endogenous electrical fields in brain function?

Research scientist positions at Vicarious
by Dileep George 07 Mar '16

07 Mar '16

Vicarious is a research startup with a long term mission to build the first human-level artificial intelligence. We believe that perception, action, reasoning, and language are intimately intertwined and need to be tackled in an integrated framework. Our work is multi-disciplinary and draws upon machine learning, graphical models, neuroscience, cognitive science, and software engineering. Vicarious is one of the few places where you'd hear cortical columns, probabilistic inference, Piagetian learning, stochastic gradient descent, and parallel implementation all discussed in the same meeting. Our strategy involves looking at the whole problem of intelligence while we make progress on different aspects of it. Trying to tackle the whole problem imposes constraints on how the different parts should behave. We have open positions for researchers to work on the following: (1) Visual perception and sensorimotor learning (2) Concept acquisition and reasoning (3) Reinforcement learning and planning (4) Grounded language understanding You will be joining a tight-knit team of scientists and engineers. Using inductive biases drawn from neuroscience, our system requires orders of magnitude less training data than traditional machine learning techniques. Our underlying framework combines advantages of deep architectures and generative probabilistic models. We use modern software engineering practices, and we strive to maintain a codebase and a culture that are a joy to work in. Visit http://www.vicarious.com/about.html for more information about the team. Qualifications/characteristics we are looking for (all are not required, but the more the better): • PhD in CS/EE/Computational Neuroscience or related disciplines. • skilled with graphical models, inference algorithms, deep learning, computer vision, machine learning, optimization • skilled in designing experiments to understand how a complex system works/fails • excellent software engineering skills • curious about how the brain works and interested in exploring how machine learning can benefit from biological constraints • willingness to pursue contrarian ideas Desired personal qualities • Integrity • Ability to admit when wrong • Altruism • Fearlessness working outside your comfort zone • Patience with others • Intellectual breadth • Sense of humor Visit http://careers.vicarious.com to learn more about the open positions and to apply.
