The Brain's Reaction to Various Circumstances
The main focus of the chemistry supplement is on how the brain reacts to various circumstances. The brain has a mechanism that encourages and rewards us when we take actions that help us live, such as avoiding danger, eating, and engaging in sexual activity. As our brains have grown smaller over time, pleasure-seeking drugs have been developed, which can contribute to addiction. Drug addiction is not the only type of addiction; other addictive habits that share the same brain circuitry also exist. The limbic system of the brain contains dependency chemistry, which controls our behavior and emotions in reaction to information. New data from the nervous system is passed by chemical messengers know as neurotransmitters that realize signals from neuron to the next. The brains produce 100 different neurotransmitters. There two types of neurotransmitters, excitatory which targets cell filled with chemical energy and inhibitory which keep target cell mellow and calm. Dopamine is the most reward chemical produced when brain believe we have a detailed note of the event. Using addictive drugs are good at messing with the level of dopamine, and also interfere with our vividly recall. Long addiction to drugs causes the brain to produce all kind of defenses with an aim to restore balance. Drugs affect the brain to change the amount of neurotransmitter artificially or imitate one of the natural neurotransmitters. Some of the drugs that operate like endorphin include heroin, morphine, and codeine. The brain responds to other drugs in a different manner in the body.
Information on Serotonin and Alcohol
Some of the new information involves the serotonin which is an inhibitory neurotransmitter which is in charge of appetite, mood, and sleep cycle. In additional endorphin produced during stress, exercise, during physical pain. The most interesting part is the addiction to alcohol. With long time use of alcohol, the brain produces excitatory neurotransmitters to faster signal transmission. When person who is used to drinking stop his body starts shaking up because the brain has no synaptic control to calm down. Another interesting part is how the brain produces at least 100 different neurotransmitters with other new one.
