Title: Neuronal Dynamics of Predictive Coding

Abstract: A critical task of the central nervous system is to learn causal
relationships between stimuli in order to anticipate events in the future,
such as the position of a moving prey or predator. What are the neuronal
phenomena underlying anticipation? In this article we review recent
results in hippocampal electrophysiology that shed light on this issue. It
is shown that the hippocampal spatial receptive fields show large and
rapid anticipatory changes in their firing characteristics. These changes
are experience- and environment-dependent and can be explained by a
computational model based on NMDA-dependent synaptic plasticity during
behavior. Striking similarities between the anticipatory network dynamics
of widely different neural circuits, such as the hippocampus and the
primary visual cortex, are discussed. These experimental and theoretical
results indicate how the macroscopic laws of synaptic plasticity give rise
to emergent anticipatory properties of receptive fields and behavior.
