Neurobiology Of Addiction

Neurobiology of Addiction What Do Drugs Do to the Brain? Drugs are chemicals. They depressive dis wander in the brain by tapping into its communication system and meddlesome with the expression nerve cells normally send, receive, and process information. Different dosesbe flummox of their chemical body structures ready differently. In fact, some drugs tolerate change the brain in ways that last hanker after the person has stop taking drugs, maybe yet permanently. This is more likely when a drug is taken repeatedly. any(prenominal) drugs, such as ganja and heroin, stumble neurons because their chemical structure mimics that of a natural neurotransmitter. In fact, these drugs nominate fool receptors, can lock onto them, and can activate the nerve cells. The problem is, they dont work the same way as a natural neurotransmitter, so the neurons wind up send abnormal messages through the brain. new(prenominal) drugs, such as amphetamine, cause nerve cells to release eb ullient amounts of natural neurotransmitters or celebrate the normal recycling of these brain chemicals (cocaine and amphetamine). This leads to an exaggerated message in the brain, ultimately wreaking havoc on the communication channels. The contrariety in effect is like the difference between mortal rustle in your ear versus someone shouting in a microphone. All drugs of abusenicotine, cocaine, marijuana, and others walk out the brains advantage circuit, which is part of the limbic system. Normally, the recall circuit responds to pleasurable experiences by releasing the neurotransmitter dopamine, which creates feelings of pleasure, and tells the brain that this is something grievouspay attention and hark back it. Drugs hijack this system, make unusually large amounts of dopamine to alluvion the system. Sometimes, this lasts for a foresightful time compared to what happens when a natural reward stimulates dopamine. This flood of dopamine is what causes the high or euph oria associated with drug abuse.
