Which neurotransmitter is primarily associated with movement and coordination?

Dopamine is primarily associated with movement and coordination, playing a crucial role in the regulation of motor control. It is produced in several areas of the brain, most notably in the substantia nigra, which is particularly involved in the control of voluntary movements. When dopamine levels are balanced, it facilitates smooth and coordinated muscle movements, allowing for precise actions.

In conditions like Parkinson's disease, where dopamine-producing neurons are damaged, individuals experience significant motor deficits such as tremors, stiffness, and difficulty initiating movement. This highlights the importance of dopamine in the proper functioning of the motor system and illustrates its critical role in both movement and coordination.
