23
Q
What is GABA? Significance of low activity?
A
- Inhibitory neurotransmitter in the brain

24
Q
What is the role of GABA in GAD?
A
- Continuous firing of neurons (anxiety, fear) triggers a feedback system –> brain and body reduce levels of excitability by releasing GABA –> GABA binds to receptors and instructs neurons to stop firing –> anxiety, fear subsides
- Peeps w/ GAD might have probs in their anxiety feedback system (too few GABA receptors, GABA receptors that don’t readily capture the neurotransmitter)
25
What comprises the brain circuit that produces anxiety reactions?
- Prefrontal cortex
- Anterior cingulate cortex

26
How do benzodiazepines and GABA play a role in GAD?
Benzodiazepines bind to GABA-A receptors --> increase ability of GABA to bind to them --> improve GABA's ability to stop neuron firing and reduce anxiety
