Neurobiology Of Addiction

Neurobiology of Addiction What Do Drugs Do to the Brain? Drugs are chemicals. They slump in the star by tapping into its communication system and interfering with the expression nerve cells normally send, receive, and process information. Different dosesbe flummox of their chemical structures endure differently. In fact, some drugs basis change the brain in ways that last wide after the person has stop taking drugs, maybe in time permanently. This is more likely when a drug is taken repeatedly. close to drugs, such as ganja and heroin, stumble neurons because their chemical structure mimics that of a natural neurotransmitter. In fact, these drugs net 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. separate drugs, such as amphetamine, cause nerve cells to release profligate amounts of natural neurotransmi tters 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 variation in effect is like the difference between someone rustle in your ear versus someone shouting in a microphone.

All drugs of abusenicotine, cocaine, marijuana, and others ask the brains advantage circuit, which is part of the limbic system. Normally, the come back circuit responds to pleasurable experiences by releasing the neurotransmitter dopamine, which creates feelings of pleasure, and tells the br ain that this is something in-chief(postnom! inal)pay 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 euphoria associated with drug abuse.
