The extension, through direct muscle actions, of the proboscis (the trunk-like extension of the mouthparts on the adult external head) in response to a sugar stimulus.

The control of viability and duration in the adult phase of the life-cycle.

Any process that modulates the frequency, rate or extent of the regulated release of dopamine.

Hyperpolarization (vertebrates) or depolarization (invertebrates) of the photoreceptor cell membrane via closing/opening of cation specific channels as a result of signals generated by rhodopsin activation by a photon.

The rhythm of the locomotor activity of an organism during its 24 hour activity cycle.

Any process that activates or increases the duration or quality of sleep, a readily reversible state of reduced awareness and metabolic activity that occurs periodically in many animals.

The part of the circadian sleep/wake cycle where the organism is asleep.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a light intensity stimulus.

Eye, head or whole body movements that help to compensate movements of the environment in order to stabilize its image on the retina. In the case of whole body movements, these motor actions may also stabilize a locomotor course in response to some disturbance. Examples include: the optokinetic reflex, which allows human eyes to follow objects in motion while the head remains stationary reflex; the optomotor responses of flying insects and swimming fish.

Any process that modulates the frequency, rate or extent of glutamate secretion, neurotransmission.
