Most Anxiolytic Drugs - Those That Are Prescribed to Relieve

Most anxiolytic drugs - those that are prescribed to relieve anxiety - act by altering the effectiveness of a neurotransmitter called GABA. What does GABA do?

A) GABA specifically increases activity in the amygdala, so reducing GABA effectiveness reduces anxiety.
B) GABA specifically reduces activity in the hypothalamus, which drives "fight-flight" arousal.
C) GABA generally inhibits neural action potentials, thereby slowing activity throughout the brain.
D) GABA interferes with the sympathetic nervous system's ability to influence peripheral organs, blocking effects such as a racing heart, sweating, and stomach discomfort commonly associated with anxiety.
