What are the effect of amphetamines to the brain?

Answer 1

"amphetamines" belong to a class of medications called psycho-stimulant 's

they work by interfering with the transmission and Re uptake of a neurotransmitter called "dopamine" A chemical messenger for your brains central reward system, this messenger carries electrical signals through the brain that are responsible for Attention, Reward, learning. Amphetamine salts clog up the cells that recycle dopamine, and send it back into the synapse transmitting the same signal once again, and this continues, amphetamine also some how are able to replace the stored dopamine in your "transmitters" and force more of it out, leaving more dopamine available to carry electric signals in the brain, which is why its street name is "speed" if there are 6x more messenger's ready to carry any signal your brain or body sends, this will greatly speed your nero activity.
