Caffeine increases a persons heart rate and helps with breathing by relaxing the air passages, and sometimes allows muscles to move easier. If a women is pregnant and drinking alcohol at the same time, this can cause fetal alcohol syndrome. It may occur with axons, neurons, myelin, synapses and glia. A modern conception views the function of the nervous system partly in terms of stimulus-response chains, and partly in terms of intrinsically generated activity patterns; both types of activity interact with each other to generate the full repertoire of behavior. By using light to activate certain neurons, we can see the kind of behavior they normally exhibit and thereby assess their impact on brain processing. An injury to it can be catastrophic and cause paralysis or in some cases, death. Heroin comes from scraping the middle of the opium poppy until it turns into a fine dust. The autonomic motor neurons innervate glands, heart muscle, and smooth muscles not under conscious control, such as the muscles that surround the intestine and other organs of the gastrointestinal tract.

These factors are age, gender, physical condition, amount of food eaten a day or anytime, weight, height, and any other medicines or drugs that may be taken. Figure Structure of typical mammalian neurons. Each has profusely branched dendrites, which receive signals at synapses with several hundred other neurons, more This expulsion acts to restore the localized negative membrane potential of the cell.

During this biophysical neural computation, information processing goes through the process of neural summation, which is a method of signal transduction.

Cholinergic System The cholinergic system is a neurotransmitter system of its own, and is based on the neurotransmitter acetylcholine ACh.
