Levenson, Jonathan M.; Sweatt, J. David; Chwang, Wilson B.; O'Riordan, Kenneth J. – Learning & Memory, 2006
Long-term memory formation is regulated by many distinct molecular mechanisms that control gene expression. An emerging model for effecting a stable, coordinated pattern of gene transcription involves epigenetic tagging through modifications of histones or DNA. In this study, we investigated the regulation of histone phosphorylation in the…

Lovibond, Peter F. – Learning & Memory, 2004
Human conditioning research shows that learning is closely related to consciously available contingency knowledge, requires attentional resources, and is influenced by language. This research suggests a cognitive model in which extinction consists of changes in contingency beliefs in long-term memory. Laboratory and clinical evidence on extinction…

Daumas, Stephanie; Halley, Helene; Frances, Bernard; Lassalle, Jean-Michel – Learning & Memory, 2005
Studies on human and animals shed light on the unique hippocampus contributions to relational memory. However, the particular role of each hippocampal subregion in memory processing is still not clear. Hippocampal computational models and theories have emphasized a unique function in memory for each hippocampal subregion, with the CA3 area acting…
