Differential involvement of mGluR1 and mGluR5 in memory reconsolidation and retrieval in a passive avoidance task in 1-day old chicks

► mGluR1 is necessary for both complete memory consolidation and reconsolidation. ► Amnesia observed after mGluR1 inhibition is definitely due to disruption of reconsolidation. ► mGluR5 is necessary for memory consolidation and reconsolidation, and for recalling information. ► Recalling process is dependent on Ca2+ release from IP3-activated intracellular stores.
