AP PSYCHOLOGY

Detailed explanation-1: -GABA-B receptors are present as autoreceptors that inhibit GABA release or heteroreceptors that reduce the release of glutamate, norepinephrine, serotonin, or dopamine.

Detailed explanation-2: -GABA is the main inhibitory neurotransmitter in your brain, stopping the chemical messages from passing from nerve cell to nerve cell.

Detailed explanation-3: -These may include overeating, gambling, and alcohol or drugs – all of which can decrease the level of naturally occurring GABA in the body and create a damaging cycle of abuse.

Detailed explanation-4: -GABA is considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system.

Detailed explanation-5: -While generally inhibitory in the adult brain, GABAA receptor activation is excitatory under certain conditions in which the GABA reversal potential is shifted positive due to intracellular Cl− accumulation, such as during early postnatal development and brain injury.
