Explorations in Hippocampal Replay - Neural Mechanisms of Learning and Memory

Watch a 46-minute neuroscience lecture exploring the complex phenomena of hippocampal replay, delivered by UC Berkeley Associate Professor David Foster. Delve into how neurons in the hippocampus activate in specific sequences during rest or sleep that correspond to patterns observed during wakeful behavior. Learn about the evolution of replay research from initial observations of simple sleep-based recapitulation to current understanding of more sophisticated processes including reverse sequencing and novel composite experiences. Discover how replay occurs during both sleep and waking states, potentially serving roles in memory consolidation, learning environmental structure, and future behavior prediction. Examine experimental results from Foster's lab investigating connections between replay and cognitive processes, including maze learning and repeated environmental exposure, revealing broader implications for understanding memory formation and neural information processing.
