What does GABBA do?

Explanation:
GABA is the brain’s main inhibitory neurotransmitter. When GABA binds to its receptors, it opens chloride channels, hyperpolarizing neurons and making them less likely to fire. This dampens overall brain activity, leading to calming effects, slower reflexes, and a more relaxed state. In other words, GABA slows you down. That’s why the description fits best: it slows you down rather than increasing arousal, improving memory, or enhancing motor coordination. Memory and attention rely more on excitatory signaling and other neurotransmitters, and while GABA helps regulate movement, its primary effect is to suppress excessive neural activity, not to enhance motor performance.
