Neurochemistry is the branch of neuroscience devoted to the study of neurochemicals. A neurochemical is an organic molecule that participates in neural activity. This term is often used to refer to neurotransmitters and other molecules such as neuro-active drugs that influence neuron function.
Examples of neurochemicals:
Neuropeptide oxytocin is involved in the control of maternal behavior. A large amount of oxytocin is made in the hypothalamus, transported to the posterior lobe of the pituitary and released into the blood stream by which it reaches target tissues such as the mammary glands (milk letdown).
Glutamate is the most common neurotransmitter. Most neurons secrete with glutamate or GABA. Glutamate is excitatory, meaning that the release of glutamate by one cell usually causes adjacent cells to fire an action potential.
GABA is an example of an inhibitory neurotransmitter.
Dopamine is another example of a neurotransmitter. It plays a key role in the functioning of the limbic system, which is involved in emotional function and control. It also plays a part in movement, alertness, and sensations of pleasure.
Serotonin plays a regulatory role in mood, sleep, and other areas.
Acetylcholine assists motor function and is involved in memory.
