AP PSYCHOLOGY

Detailed explanation-1: -Serotonin. Serotonin is an inhibitory neurotransmitter. Serotonin helps regulate mood, sleep patterns, sexuality, anxiety, appetite and pain.

Detailed explanation-2: -Gamma-aminobutyric acid (GABA) is an amino acid that functions as the primary inhibitory neurotransmitter for the central nervous system (CNS). It functions to reduce neuronal excitability by inhibiting nerve transmission.

Detailed explanation-3: -Also known as GABA, gamma-aminobutyric acid is an inhibitory neurotransmitter that acts as a brake to the excitatory neurotransmitters. GABA has wide distribution in the brain and has a major role in reducing neuronal excitability throughout the nervous system.

Detailed explanation-4: -A single neuron may have thousands of other neurons synapsing onto it. Some of these release activating (or depolarizing) neurotransmitters; others release inhibitory (or hyperpolarizing) neurotransmitters. GABA is the primary inhibitory neurotransmitter, which means it decreases the neuron’s action potential.

Detailed explanation-5: -When a neurotransmitter like GABA is acting in an inhibitory manner, it will cause hyperpolarization of the postsynaptic cell membrane. When a neuron is hyperpolarized, it is less likely to fire an action potential.
