Research Abstract

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.
