1209-组胺能神经元调控记忆提取的脑态机制

from 聊聊Sci

这项研究揭示了组胺神经元如何通过一种特殊的超慢速动态(0.05–0.1 Hz)来调控记忆的提取。研究人员发现,这种神经活动的波动能够追踪复杂的脑体状态,并预判小鼠在特定时刻能否成功回忆起奖励关联。实验证明,当下丘脑的组胺活动处于高水平时,会通过启动机制增强基底外侧杏仁核(BLA)对线索的群体反应,从而开启记忆的访问权限。反之,若在刺激出现前抑制这些神经元,则会导致记忆表现下降。该成果提出了一种启动状态模型,解释了为何记忆在不同时刻存在可及性的波动。这种机制在进化上具有节能优势,为理解记忆波动和相关神经疾病提供了新视角。References:Morishita Y, Takamura Y, Nishimura K, Yokoi Y, Ishihama Y, Idutsu R, Ono M, Matsumoto R, Hitora-Imamura N, Minami M, Nomura H.
