Abstract

Spike packet code is one of the least explored in the brain. Packet coding is based on three principles: 1) Sensory flow is composed of a series of discrete self-generated sensory image whose precise timing is separately encoded in the brain. 2) Images are encoded in the temporal structure of spike evoked trains, defined by onset time, inter-spike intervals, and spike number. 3) Packet information should be stored in some manner that allows memories to operate with subsequent sensory inputs. This form of coding may facilitate neural computations underlying natural behaviors, encompassing aspects such as novelty detection and boundary recognition. This article reviews some contributions from weakly electric fish that have advanced both the experimental and theoretical understanding of the spike packet neural code.
