Answer: ACETYLCHOLINE
ACETYLCHOLINE causes the muscles fibers in the legs to contract enabling us to move as well stimulate the neurons we need to learn new information. Acetylcholine is the target of many neurotoxins of which a good number of them are deadly.
ACETYLCHOLINE is a neurotransmitter that is synthesized by cholinergic neurons, acetylcholine is involved with the central and peripheral nervous system.
Drugs and chemicals the has a negative effect on acetylcholine causes paralysis and convulsion due to impairment in muscle contraction.
Acetylcholine enhances the effect of the feedforward afferent input to the cortex of the brain,this in-turn enhances the encoding of memory and as well stimulate the neurons we need to learn new information.
