摄入激活的 CGRP 神经元控制学习而非饱腹感

Ingestion-activated CGRP neurons control learning but not satiety

AI 导读

Jarvie 等人识别出两群臂旁 CGRP 神经元:一群在摄入时对食物相关信号快速响应,另一群对厌恶性的内脏线索缓慢响应。摄入期间快速 CGRP 神经元的激活是摄入后学习所必需的,但并非此前认为的饱腹感所必需。

摘要

Jarvie et al. identify two populations of parabrachial CGRP neurons, one that responds rapidly to appetitive signals during ingestion and the other that responds slowly to aversive visceral cues. The rapid CGRP neuron activation during ingestion is shown to be required for post-ingestive learning but not, as previously believed, satiety.
