Molecular mechanisms involved in taste learning and memory

Topical Section: Molecular Research of Learning and Memory

Taste learning, and particularly conditioned taste aversion (CTA), is an adaptive learning involving complex brain mechanisms and molecular pathways. Taste learning and CTA are critical behaviors for survival, and the knowledge of the molecular bases involved in the acquisition, retention and extinction of CTA can help to understand the brain mechanisms of normal and altered taste learning. The aim of this review is to describe recent findings on the molecular mechanisms of taste learning, from the genetic, receptors, and intracellular and extracellular signaling biological levels. We can conclude that some molecular pathways and processes for the acquisition of taste learning and the formation of taste memories are well identified. However, new molecular, neurobiological and behavioral studies are needed to thoroughly elucidate the complexity of the taste system and the neural mechanisms of CTA.
