What are the effects of nicotine on the brain?
nicotine is a naturally occurring chemical found in the leaves of tobacco plants. Many people smoke or chew tobacco products to accept this substance. There are several effects of nicotine on the brain, including increasing the release of neurotransmitters that stimulate consciousness, pleasure and memory centers. Over time, some users have become physically and psychologically dependent on these effects and, if they stop ingesting tobacco, suffer from withdrawal symptoms. A research study has been conducted to see if nicotine could help patients suffering from Alzheimer's disease or Tourette syndrome. Nicotine is a fast -acting stimulant and can cross the blood -brain barrier less than a minute after smoking. Once this chemical compound is in the brain, it binds to acetylcholine receptors and promotes the release of North Neurotransmitters. It can do this because nicotine has a similar shape to the acetylcholine body.
The release of these neurotransmitters is one of the most important effects of nicotine on the brain because these molecules help regulate many body functions. Relaxed neurotransmitters stimulate cholinergic areas of the brain and help improve the range of attention and reaction time. When a person becomes addicted to nicotine, it may be difficult to concentrate or focus on a specific task if he is without a cloth for a while. Tobacco decomposes rapidly in the human body, so dependent may need to be smoked or chewed regularly to maintain the desired effects of nicotine on the brain.
Dopamine is another neurotransmitter that is released after the absorption of nicotine compounds. This neurotransmitter is assumed to affect the areas of pleasure in the brain reward centers. The stimulation of these areas makes a person more relaxed and happier and can help suppress hunger in some people. These effects can explain why people consider nicotine a reward during their working day. This can also explainLit, why some people are gaining weight after the end, because Nicotin acted to suppress his hunger.
When using tobacco may have significant disadvantages, some scientists believe that the effects of nicotine on the brain can be used to treat certain conditions. The first neurons damaged by Alzheimer's disease are the same that stimulated nicotine, so some believed that the use of nicotine could help slow the progress of the disease. Nicotin patches are also sometimes administered by patients suffering from Tourette syndrome to help control their physical behavior.
