Taste's memory

Abstract

Gustatory novelty ‘detection requires the comparison between on line sensorial information and off line information, i.e. memory; from there a cascade of events is trigger when a maladjustment between these situations is detected. This process require neuromodulator´s pathways, which involved several systems in different cerebral areas acting in parallel, modulating the gene expression, and at last altering the cortical pathways which encode the new information. The acquisition of this information can be study through different experimental procedures, in which the associations between the gustatory stimuli and the gastrointestinal consequences are evaluated. The main evidences in rodents of the neurotransmission systems mostly involved in the flavor memory, for the appetitive and aversive memories are revised in this work.
