A theoretical understanding of neural activity in the brain requires powerful mathematical techniques capable of handling a, nonlinear and noisy behavior. Throughout the past decades, many approaches originally developed for theoretical physics were adapted for problems in the neurosciences. Perhaps one of the most successful techniques to be refitted is the so-called mean-field theory for population dynamics. This approach was pioneered by Grossberg (1967) and Wilson, Cowan (1972) and others. Their key results were instrumental to important findings and predictions in computational neuroscience. Later on, the theory was extended with the inclusion of second-order statistics by van Vreeswijik and Sompolinski (1996) describing the observed irregular activity of excitatory and inhibitory neurons in cortex, so-called the balanced state.

Although adapted mean‐field approaches are successful in providing a good base for many experimental and theoretical observations, their limited “averaging” scope fails to capture many important features of populations dynamics. For instance, phenomena that include spike dependent learning rules or network dynamics driven by external stimulations remain elusive. Moreover, it is unclear what mathematical techniques are needed to address these shortcomings.

This workshop will focus on the inherent difficulties of neural population dynamics problems and newly arising research topics. The meeting aims to serve as a forum for key researchers working with mean-field approaches and/or their emerging alternatives to exchange their tools and views.

Registration:

Attendance of the workshop is free but limited. Seats will be allocated on first-come-first-served basis. Please note that members of the Bernstein Network and the Bernstein Association will be given preference. Please register here.

Abstract submission deadline extended! Poster submissions are highly encouraged. Please submit your abstracts before April 15, 2015 until April 28, 2015, here. You will be informed about your registration at the end of April 2015.

Due to the limited time and a schedule that promotes exchanges of advanced research ideas, talks are by invitation only. However, the organizers will try to allocate a few short talk slots for selected submitted abstracts.
