Light is one of the strongest influences of the suprachiasmatic nucleus (SCN) which is part of the hypothalamus in the brain that controls the circadian rhythm in most animals.

He discovered the optic chiasma by anatomical studies of the brain.

As in other lepidopterans, early prophase I stage of meiosis occurs as normal, but there is no crossing over or chiasma formation in the females at the prophase I stage.

Most noise commonly occurs below a voltage-threshold that is needed for an action potential to occur, but sometimes it can be present in the form of an action potential; for example, stochastic oscillations in pacemaker neurons in suprachiasmatic nucleus are partially responsible for the organization of circadian rhythms.
