A new study examining the neural circuitry regulating sleep in Drosophila has identified a pair of dopamine neurons that signal to the fan-shaped body to suppress sleep. These neurons are separate from the dopamine neurons that regulate motivation, memory, and feeding, suggesting that independent populations of dopamine neurons regulate distinct behaviors.
一项新的研究检查了调节果蝇睡眠的神经回路,发现了一对多巴胺神经元,它们向扇形形体发出信号以抑制睡眠。这些神经元与调节动机、记忆和进食的多巴胺神经元不同,这表明独立的多巴胺神经元群体调节不同的行为。
