Here the U-shaped loop at the top shows the tract through which signals from one side of the brain are transmitted to the other.

Parkinson's disease arises because for some reason the dopamine cells in the brain are lost, and it is known that the stop signal is being over-activated somehow or other.

Beauchamp and Nath's work suggests that when the illusion occurs, it is because the superior temporal sulcus discounts some of the signals coming from one sensory region of the brain in favor of others.

In the absence of that protein, other proteins involved in transmitting signals between neurons in the brain are overproduced, notably mGluR5, a receptor for the neurotransmitter glutamate.

FosB is a transcription factor in the brain which, together with other molecules, is involved in so - called signal transduction (transmission of stimuli to the cells), that is to say conveys genetic information between the cells and also determines whether certain genes are activated or not.

Receptors facilitate chemical and electrical signals between neurons in the brain, allowing those neurons to communicate with each other.
