Baker, Kathryn D.; McNally, Gavan P.; Richardson, Rick – Learning & Memory, 2012
The NMDA receptor partial agonist d-cycloserine (DCS) enhances the extinction of learned fear in rats and exposure therapy in humans with anxiety disorders. Despite these benefits, little is known about the mechanisms by which DCS promotes the loss of fear. The present study examined whether DCS augments extinction retention (1) through reductions…

Wells, Audrey M.; Lasseter, Heather C.; Xie, Xiaohu; Cowhey, Kate E.; Reittinger, Andrew M.; Fuchs, Rita A. – Learning & Memory, 2011
Contextual stimulus control over instrumental drug-seeking behavior relies on the reconsolidation of context-response-drug associative memories into long-term memory storage following retrieval-induced destabilization. According to previous studies, the basolateral amygdala (BLA) and dorsal hippocampus (DH) regulate cocaine-related memory…

Colon-Cesario, Wanda I.; Martinez-Montemayor, Michelle M.; Morales, Sohaira; Felix, Jahaira; Cruz, Juan; Adorno, Monique; Pereira, Lixmar; Colon, Nydia; Maldonado-Vlaar, Carmen S.; Pena de Ortiz, Sandra – Learning & Memory, 2006
Nurr1 expression is up-regulated in the brain following associative learning experiences, but its relevance to cognitive processes remains unclear. In these studies, rats initially received bilateral hippocampal infusions of control or antisense oligodeoxynucleotides (ODNs) 1 hour prior to training in a holeboard spatial discrimination task. Such…
