Question

Quizplus · Accepted Answer

The inhibitory effects of GABA act to stabilize the electrical activity of the brain. A deficiency in GABA activity has been linked to anxiety disorders, and drugs that enhance GABA function (such as benzodiazepines) are commonly used to treat anxiety. An excess of GABA has not been linked to epilepsy. GABA is not involved in Parkinson's disease; dopamine is the primary neurotransmitter implicated in this disorder.
