Talk Title
Theoretical Analysis of Learning with Reward-Modulated Spike-Timing-Dependent Plasticity
Talk Abstract
Reward-modulated spike-timing-dependent plasticity (STDP) has recently emerged as a candidate for a learning rule that could explain how local learning rules at single synapses support behaviorally relevant ada ptive changes in com- plex networks of spiking neurons. However the potential and limitations of this learning rule could so far only be tested through computer si mulations. This ar- ticle provides tools for an analytic treatment of reward-mo dulated STDP, which allow us to predict under which conditions reward-modulate d STDP will be able to achieve a desired learning effect. In particular, we can p roduce in this way a theoretical explanation and a computer model for a fundamental experimental finding on biofeedback in monkeys (reported in [1]).
