The Neurotransmitters:
The main neurotransmitters of the brain consist of 6. The
first is Acetylcholine; its major function is excitatory at the synapses
involved in muscular movement and memory. The second is Norepinephrine, it is
excitatory and inhibitory at various sites, it is involved in neural circuits
controlling learning, memory, wakefulness, and eating. Serotonin is the 3rd
neurotransmitter, it is also inhibitory and excitatory and is involved in
sleep, mood, and arousal and may be involved in pleasure and pain. Dopamine is
excitatory and involved in voluntary movement, emotional arousal, learning,
memory, and experiencing pleasure and pain. GABA is inhibitory and works in the
motor system- movement. The last neurotransmitter is endorphin; it inhibits
transmission of pain impulses.
