Analysis of the circadian brain network resposible for light entrainment in Drosophila melanogaster

果蝇黑腹果蝇有多种光输入途径，用于昼夜节律时钟的光干扰。特别是蓝光光色素隐花色素（CRY）在这一途径中起着重要作用。在这里，我们研究了负责哭泣依赖的光夹带的大脑神经网络。我们发现，起搏器神经元的一个子集促进果蝇从8小时时差中恢复过来，这表明有一种神经机制参与了光的携带速度。

The fruit fly Drosophila melanogasterhas multiple light-input pathways for light entrainment for the circadian clock. Especially, a blue light photo-pigment Cryptochrome (CRY) plays an important role in the pathway. Here, we investigated the brain neural network responsible for the CRY-dependent light entrainment. We found that a subset of pacemaker neurons promotes recovery from 8 h Jetlag in Drosophila, suggesting that there is a neural mechanism involved in the speed of light-entrainment.
