Clock Neurons

Caption

Light affects the clock neurons in the fly brain in three ways: The first light input to the clock neurons is via the cryptochrome (CRY); this light input is responsible for the detection of low-intensity light (LI). The second light input works via the compound eyes and basically detects middle-intensity light (MI). The third light input is responsible for the detection of high-intensity light (HI). It operates through the Hofbauer-Buchner eyelets (HB eyelets). Morning cell (M cells) control the morning activity, evening cells (E cells) the evening activity.
