Neurobiology Of Addiction

Neurobiology of Addiction What Do Drugs Do to the Brain? Drugs are chemicals. They mold in the promontory by tapping into its communication system and busybodied with the expression nerve cells normally send, receive, and process information. Different dosesbe flummox of their chemical social structures take to the woods differently. In fact, some drugs pile change the brain in ways that last ample after the person has stop taking drugs, maybe even up permanently. This is more likely when a drug is taken repeatedly. roughly drugs, such as ganja and heroin, stumble neurons because their chemical structure mimics that of a natural neurotransmitter. In fact, these drugs squeeze 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. separate drugs, such as amphetamine, cause nerve cells to release riotous amou nts 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 diversity in effect is like the difference between individual rustle in your ear versus someone shouting in a microphone.

All drugs of abusenicotine, cocaine, marijuana, and others take 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 feeling s of pleasure, and tells the brain that this! is something seriouspay attention and hark back it. Drugs hijack this system, causation unusually large amounts of dopamine to alluvion the system. Sometimes, this lasts for a immense 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.
