👉 Dopamine is a neurotransmitter in the nervous system that plays a significant role in mood, pleasure, and motivation. It is produced by neurons in the brain and is released into the synaptic cleft through the release of dopamine receptors on the postsynaptic membrane. Dopamine has been shown to have various effects on behavior, including increased reward-seeking behaviors, decreased aggression, improved memory, and enhanced mood. In summary, dopamines are neurotransmitters that regulate mood and behavior in the brain.
