Definition
Benzodiazepines are a class of psychoactive drugs that enhance the activity of gamma-aminobutyric acid (GABA) in the brain. They work by increasing the inhibitory effects of GABA, resulting in relaxation and sedation.
GABA is an inhibitory neurotransmitter in the brain that helps reduce neuronal excitability. It acts as a natural brake system, preventing excessive firing of neurons.
Receptors are protein structures located on cell membranes that receive chemical signals from neurotransmitters like GABA. They can activate or inhibit various cellular responses when stimulated.
Sedation: Sedation refers to a state of calmness induced by suppressing central nervous system activity. It can result in reduced anxiety, drowsiness, and relaxation.
