In the brain, as in other parts of the body, chains of nerve cells make up nerve tissues that are responsible for the transmission of nerve impulses. They are released, flood the synaptic junction, stimulate the adjoining nerve receptors and then are re-absorbed or destroyed by enzymes. The newly stimulated nerve continues transmission of the nerve impulse. BY DRUG Hallucinogens produce their effects by affecting the neurotransmitter. The result is altered nerve impulse transmission that can cause the changes in perception and hallucinations that accompany the use of these drugs.
