visceral effector

Norepinephrine (NE)

it is an excitatory neurotransmitter. It causes pleasant mood and increased attentiveness in the brain. It causes blood vessels vasoconstriction to increase blood pleasure.

Dopamine

it is an excitatory neurotransmitter. It helps with learning. Associated with pleasant sensation and desire. Often nicknamed the "addiction" neurotransmitter due to its association with addictions. It increases heart rate and force of contraction.

Serotonin

This neurotransmitter increases mood (decreased levels are associated with depression). It stimulates sleep and inhibits appetite.

Endorphin

A type of peptide that decreases sensation of pain. Known as the body's "natural opiates"

GABA

It is the main inhibitory neurotransmitter. Individuals prone to anxiety prone to anxiety may have reduced levels.

Glutamate

It is the main excitatory neurotransmitter and it important in memory and learning.
