Difference between Brainstem and Dopamine

Brainstem vs. Dopamine

The brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord. Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the brain and body.

Area postrema

The area postrema is a medullary structure in the brain that controls vomiting.

Midbrain

The midbrain or mesencephalon (from Greek mesos 'middle', and enkephalos 'brain') is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.

Spinal cord

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

Thalamus

The thalamus (from Greek θάλαμος, "chamber") is the large mass of gray matter in the dorsal part of the diencephalon of the brain with several functions such as relaying of sensory signals, including motor signals, to the cerebral cortex, and the regulation of consciousness, sleep, and alertness.

Ventral tegmental area

The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.
