Amygdalar circuits required for either consolidation or extinction of taste aversion memory are not required for reconsolidation.

摘要: Recent reports have revitalized the debate on whether, for each item in memory, consolidation occurs just once, or upon their activation retrieval, items memory undergo reconsolidation. Further, it has been recently reported that following retrieval absence of reinforcer, activated can either reconsolidate extinguish, depending training history. This raises question whether consolidation, extinction and reconsolidation share neuronal mechanisms, moreover, recapitulates consolidation. In conditioned taste aversion (CTA), depends protein synthesis central nucleus amygdala, whereas basolateral nuclei amygdala. Here we show inhibition these no effect CTA under conditions initiate implies does not recapitulate are different processes.
