Neural circuits influence food intake by responding to interoceptive hunger cues and/or hedonic cues. A new study utilizes a hunger discrimination behavioural task combined with opto- and chemo-genetic manipulation to identify hunger and non-hunger sensing neural circuits driving food intake.

神经生物学：如何询问老鼠是否饿了

神经回路通过响应内感受性饥饿线索和/或享乐线索来影响食物摄入。一项新研究利用饥饿歧视行为任务结合光遗传学和化学遗传学操作来识别驱动食物摄入的饥饿和非饥饿感测神经回路。
