Question

One biological explanation for generalized anxiety disorder suggests there is ______ available in the brain.

a) too little GABA
b) too little dopamine
c) too much GABA
d) an excess of serotonin

Answer 1

Too little GABA in the brain is a biological explanation for generalized anxiety disorder, as GABA is the main inhibitory neurotransmitter responsible for regulating anxiety levels.

Step-by-step explanation:

A biological explanation for generalized anxiety disorder suggests that there is too little GABA available in the brain. Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the central nervous system, which helps to regulate anxiety levels by tempering neuronal excitability. When GABA levels are low, the brain's natural ability to manage stress and anxiety diminishes, potentially leading to conditions such as generalized anxiety disorder.
