Differential locus coeruleus–hippocampus interactions during offline states
· 2026-09-04 · 原文
Patterns of locus coeruleus (LC) activity and norepinephrine (NE) release during non-rapid-eye-movement sleep suggest a critical role for the LC–NE system in offline modulation of forebrain circuits. NE transmission promotes synaptic plasticity and is required for memory consolidation, but the field has only begun to uncover how LC activity contributes to coordinated forebrain network dynamics. Hippocampal ripples, a hallmark of memory replay, are temporally coupled with thalamocortical oscillations; however, the circuit mechanisms underlying system-level consolidation across larger brain networks remain incompletely understood.
