Spike-based computation

Workshop at CNS Paris 2013

Organizers: Romain Brette (romain.brette@ens.fr) and Sophie Denève (sophie.deneve@ens.fr)

Date: July 18

According to David Marr, computational systems can be analyzed at three levels: the computational level (what does the system do?), the algorithmic or representational level (how does it do it?) and the physical level (how is it physically realized?). Traditionally, in computational neuroscience, the algorithmic level is described in terms of firing rates, while the physical level is seen as a translation of these algorithms in terms of spikes. For example, spike trains may be produced as realizations of Poisson processes with the underlying firing rates. In other words, rate-based approaches postulate that the algorithmic and physical levels are independent. Spike-based approaches to neural computation have in common that they question the independence of these levels. Instead, algorithms and representations are defined at the level of spikes. The goal of this workshop is to present the various flavors of spike-based computation. It will consist of a series of short presentations covering recent research, with ample time for discussion. This will be a one-day workshop with a series of short talks and ample time for discussion.
