Extract of sample "Effects of Drugs on the Brain"

Download file to see previous pages Nevertheless, enhancement is not confined to neuroscience but it is distinct about the enhancement of the mental, behavior, and also cognitive functions. It all takes place as a result of the brain being the center of a person. Cocaine, heroin, ecstasy, and cannabis all affect the human brain whereby some of their effects are unique while others vary from one drug to the other as the document discusses.
The addiction to cocaine as a drug involves two characteristics that are of great importance. One of the characteristics is the chronic compulsive and the second is the drug use that is not controllable. It also entails the withdrawal of the syndrome when a person stops to use the drug. There have been the developments of animal models to aid in motivation towards drug dependence. They enable the exploration of mechanisms in neurobiology, independence of drugs (Bickerstaff, 2009).
Cocaine stimulates the central nervous system thus increasing the neurotransmitter dopamine levels in brain circuits. The resultant effect is the regulation of movement and pleasure. The effect tends to be similar to those of cannabis, heroin, and ecstasy. The neurons normally release the dopamine. The aspect brings about another similarity of cocaine to other drugs in that it causes some effects to the neurons in the human brain. However, as opposed to other drugs cocaine tends to shut off signals between the neurons (Connolly, 2001).
Cocaine tends to prevent the recycling process of dopamine hence causing large amounts of dopamine to build up between neurons. The aspect amplifies the dopamine’s signal and eventually disrupts normal communication of the brain. The flooding of dopamine increases cocaine’s characteristics. As other types of drugs such as cannabis, ecstasy, and heroin, repeated cocaine use results in long-term changes in the reward systems of the brain and other brain systems. ...Download file to see next pagesRead More
