Sedatives: These are substances that induce sedation by reducing irritability or excitement. Like softer blankets gently calming down an overly active child before bedtime.
Anesthesia: This is a state of controlled temporary loss of sensation or awareness induced for medical purposes. It's like a super heavy-duty blanket that not only puts the brain to sleep but also blocks out any sensation of pain.
Depressants: These are drugs that lower neurotransmission levels, which is to dampen arousal or stimulation in various areas of the brain. They're like different types of blankets (quilts, comforters, throws) that can slow down or calm activity.
