Central nervous system (CNS) depressants produce a calming effect by what action on the transmission of nerve impulses to the CNS?

Explanation:
CNS depressants calm the brain by reducing the transmission of signals into the CNS. They typically enhance inhibitory neurotransmission, especially GABAergic activity, which makes neurons less likely to fire and lowers overall CNS activity. This decreased transmission leads to sedation and a calming effect. If something were stimulating, enhancing, or accelerating, it would raise CNS activity rather than quiet it, so those ideas don’t fit.
