Post-Acquisition Release of Glutamate and Norepinephrine in the Amygdala Is Involved in Taste-Aversion Memory Consolidation
Peer reviewed Peer reviewed

Guzman-Ramos, Kioko; Osorio-Gomez, Daniel; Moreno-Castilla, Perla; Bermudez-Rattoni, Federico – Learning & Memory, 2012
Amygdala activity mediates the acquisition and consolidation of emotional experiences; we have recently shown that post-acquisition reactivation of this structure is necessary for the long-term storage of conditioned taste aversion (CTA). However, the specific neurotransmitters involved in such reactivation are not known. The aim of the present…

Rekart, Jerome L.; Sandoval, C. Jimena; Bermudez-Rattoni, Federico; Routtenberg, Aryeh – Learning & Memory, 2007
Relating storage of specific information to a particular neuromorphological change is difficult because behavioral performance factors are not readily disambiguated from underlying cognitive processes. This issue is addressed here by demonstrating robust reorganization of the hippocampal mossy fiber terminal field (MFTF) when adult rats learn the…

Perirhinal Cortex Muscarinic Receptor Blockade Impairs Taste Recognition Memory Formation
Peer reviewed Peer reviewed
Direct linkDirect link
Gutierrez, Ranier; De la Cruz, Vanesa; Rodriguez-Ortiz, Carlos J.; Bermudez-Rattoni, Federico – Learning & Memory, 2004
The relevance of perirhinal cortical cholinergic and glutamatergic neurotransmission for taste recognition memory and learned taste aversion was assessed by microinfusions of muscarinic (scopolamine), NMDA (AP-5), and AMPA (NBQX) receptor antagonists. Infusions of scopolamine, but not AP5 or NBQX, prevented the consolidation of taste recognition…
