Parkinson's disease is caused by the death of neurons in the brain that produce dopamine, a chemical that shuttles signals between neurons and is responsible for controlling the body's movement.

Multiple sclerosis (MS) is caused by immune cells that activate a cascade of chemicals in the brain, attacking and degrading the insulation that keeps neuronal signals moving.

In another test, the researchers looked to see if chemical signals released from the endothelial cells would cause the media layer to relax and constrict, as they do in the human body.

Antipsychotics According to a 2014 review of eight studies, as many as 55 percent of patients who take modern antipsychotics experience weight gain — a side effect that appears to be caused by a disruption of the chemical signals controlling appetite.

Although the scientists can't assume hospitalization is directly causing suicide, they say their work backs up a hot theory that inflammation — one of the body's main defenses against infection — influences depression by generating a chemical that interferes with brain signaling.

Studies in animals indicated that in branches of the nerve that exit from the back of the brain and wrap around various parts of the face and head, overactive cells would respond to typically benign lights, sounds and smells by releasing chemicals that transmit pain signals and cause migraine.

Parkinson's disease is caused by loss of the brain signaling chemical dopamine and affects about 1 million people in the United States.
