Abstract

There is growing evidence in a number of cortical areas that individual spikes, beyond just gross firing rates averaged over hundreds of milliseconds, play a central role in neural information processing. However, it is not yet well characterized what computations may be supported by network dynamics in which spikes count beyond the "spike-counts". In this workshop we bring together a variety of theoretical as well as experimental approaches, ranging from dynamical systems to Bayesian inference and from in vitro to in vivo recordings, and explore how spiking-based dynamics can be useful for performing a number of neurobiologically relevant computations.
