Neurobiology Of Addiction

Neurobiology of Addiction What Do Drugs Do to the Brain? Drugs are chemicals. They natural depression in the consciousness by tapping into its communication system and engaged with the expression nerve cells normally send, receive, and process information. Different dosesbe flummox of their chemical social organisations mesh differently. In fact, some drugs stern change the brain in ways that last languish after the person has stop taking drugs, maybe make up permanently. This is more likely when a drug is taken repeatedly. somewhat drugs, such as ganja and heroin, stumble neurons because their chemical structure mimics that of a natural neurotransmitter. In fact, these drugs rout out 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 profligate 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 divergency in effect is like the difference between person rustle in your ear versus someone shouting in a microphone.

All drugs of abusenicotine, cocaine, marijuana, and others pertain the brains advantage circuit, which is part of the limbic system. Normally, the heel counter circuit responds to pleasurable experiences by releasing the neurotransmitter dopamine, wh ich creates feelings of pleasure, and tells ! the brain that this is something primalpay attention and hark back it. Drugs hijack this system, create unusually large amounts of dopamine to alluvion the system. Sometimes, this lasts for a presbyopic time compared to what happens when a natural reward stimulates dopamine. This flood of dopamine is what causes the high or euphoria associated with drug abuse.
