PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -If cocaine is present, it attaches to the dopamine transporter and blocks the normal recycling process, resulting in a buildup of dopamine in the synapse, which contributes to the pleasurable effects of cocaine.

Detailed explanation-2: -Dopamine, epinephrine and norepinephrine are the main catecholamines (a label based on having part of the same molecular structure). These hormones are made by your adrenal gland, a small hat-shaped gland located on top of each of your kidneys. Dopamine is also a neurohormone released by the hypothalamus in your brain.

Detailed explanation-3: -Cocaine increases dopamine levels by inhibiting reuptake through the dopaminergic transporter. However, this mechanism is insufficient to account for all of the actions of cocaine on the dopaminergic system.
