Can local inhibition lead to long-range competition?
by Dylan Richard Muir 10 Nov '14

10 Nov '14

Dear colleagues, We would like to draw your attention to a recent publication, where we examine the spatial range of competition expected for columnar visual cortex, given known features of cortical anatomy. Reprints are freely available from the author’s homepage (see link below). Models of cortex that assume long-range competition are widespread, although it has long been known through anatomical studies that the spatial extent of inhibition is in fact more restricted than that of excitation. We analyzed straightforward models of interacting cortical columns, and performed simulations of larger models, to show how the spatial scales of excitation and inhibition interact to produce competition through disynaptic inhibition. We found that although disynaptic inhibition is widespread, the presence of competition across the cortical surface is predicted well by the anatomy of direct excitatory and inhibitory coupling. In comparison, the effect of multisynaptic network interactions was very small. This implies that for realistic models of cortex, which should include short-range inhibition and longer-range excitation, the spatial extent of competition is likely to be even narrower than the range of inhibitory connections.

Postdoctoral position in computational systems neuroscience (sensory processing & decision-making)
by Ralf Haefner 10 Nov '14

10 Nov '14

Postdoctoral position in computational systems neuroscience (sensory processing & decision-making) We are looking for a postdoctoral researcher to join the group of Ralf Haefner in the department for Brain & Cognitive Sciences at the University of Rochester (NY). The focus of our group is on understanding the neural basis of perceptual inference. Based on the assumption that the brain performs probabilistic inference using an internal model of the world, we ask questions such as: What is the nature of the internal model? How is it learnt? How are posterior beliefs represented by spiking responses of populations of neurons and what algorithm does the brain use to compute its beliefs? The position requires strong mathematical and good programming skills. The ideal candidate would also be familiar with machine learning techniques, especially regarding generative models and MCMC-sampling-based probabilistic inference. Possible research projects range from purely theoretical to data-driven. Our collaborations with electrophysiology labs allow for testing of theoretical models using state-of-the-art cortical population recordings in vivo and, if desired, the opportunity to record your own data. More information about past work is available here: http://tinyurl.com/rmhaefner and a preprint of a manuscript representative of future work here: http://arxiv.org/abs/1409.0257 For details on current and possible future projects, and general information, please contact us directly. The successful candidate with join a world-class department with a wide range of research interests ( https://www.bcs.rochester.edu/research/index.html ) and a strong tradition in probabilistic modeling. Start date and duration are flexible. Please send applications including a CV and names of 2-3 references by email. Please contact us as soon as possible if you'd like to meet at the upcoming SfN or NIPS conferences.

Faculty position in Information Engineering and Medical Neuroscience Department of Engineering, University of Cambridge, UK Applications are invited for a University Lectureship (~ US Assistant /Professor equivalent) in the Control Group in the Department of Engineering. Exceptional candidates are sought with the potential to develop a record of world-class research commensurate with the Department’s international reputation. The current faculty members in the Cambridge Control Group are: Emeritus Professor Keith Glover, Professor Jan Maciejowski, Professor Rodolphe Sepulchre (Professor of Engineering), Professor Malcolm Smith (Head of Group) and Dr Glenn Vinnicombe (Reader). Candidates will be expected to contribute to undergraduate and graduate teaching in the general area of Control Engineering and possibly other related areas of Information Engineering. The closing date for applications is 9 January, 2015. The interviewing panel will meet soon after the closing date. Short-listed candidates will be invited to visit the Department, give a short seminar/lecture and attend a formal interview. The field of this University Lectureship is at the interface between Information Engineering and Medical Neuroscience. Unprecedented challenges and opportunities exist in this area as a consequence of a fast-developing technology of actuating and sensing devices at the neuronal scale (e.g. neural implants, multi-electrode recordings, and optogenetic techniques). The successful candidate will preferably be working in the field of Control Engineering with a research record in problems of medical neuroscience, and with appropriate theoretical expertise (nonlinear systems). It could be filled by someone whose primary expertise is in a different branch of Information Engineering, but the ability to contribute to teaching in one or more of the ‘core’ areas of Information Engineering (Control, Signal processing, Information theory, etc) will be expected. Medical neuroscience and brain science is a current focus of most national and international funding agencies. Funding opportunities will exist in conjunction with Cambridge Neuroscience. The lectureship will strengthen the Department’s Bioengineering strategic theme. Informal enquiries can be made to Professor Rodolphe Sepulchre (r.sepulchre(a)eng.cam.ac.uk) or Professor Malcolm Smith (mcs(a)eng.cam.ac.uk).

Dear Colleagues, Please pass the following information along to your undergraduates who plan to pursue a PhD in Cognitive Neuroscience beginning in the Fall of 2015. Faculty at the University of Wisconsin-Milwaukee (UWM) are actively recruiting graduate students who intend to earn a PhD conducting cognitive neuroscience research. UWM has an extremely energetic & cohesive group of faculty using cognitive neuroscience techniques to study the neural bases of learning & memory, attention, perception, dementia, addiction, anxiety, depression, and motor control. Collectively, our labs form a group of more than 50 faculty, postdocs, graduate students, research scientists, and research assistants all working on cognitive neuroscience at UWM. A major strength of our program is our depth - cognitive neuroscientists at UWM are part of a much broader community of researchers whose interests range from cellular to systems-level neuroscience (see http://www4.uwm.edu/neuroscience for more information about UWM's Neuroscience Program). Labs of the following cognitive neuroscience faculty are currently interested in accepting graduate students: Ira Driscoll, PhD --> Cognitive Neuroscience of Aging Lab (http://www.uwmdriscolllab.com) Adam S.
