This reference presents a detailed exploration of the synaptic tagging and capture model, which has been proposed to provide a conceptual basis for how short-term memories are transformed into long-term memories. The first edition of Synaptic Tagging and Capture served as a comprehensive introduction and overview of the field and covered the topics from molecular and cellular aspects to behavior. This second edition reflects the overwhelming amount of research on the topic in the past five years. Notably, it provides greater insight into the molecular and cellular mechanisms and behavioral aspects of tagging and capture, including reconsolidation, computational, and metaplastic models. Synaptic Tagging and Capture: From Synapses to Behavior, 2nd edition remains the definitive work in the field.
