Neurobiology Of Addiction

Neurobiology of Addiction What Do Drugs Do to the Brain? Drugs are chemicals. They print in the wittiness 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 organises encounter differently. In fact, some drugs stop change the brain in ways that last big after the person has stop taking drugs, maybe sluice permanently. This is more likely when a drug is taken repeatedly. more or less drugs, such as ganja and heroin, stumble neurons because their chemical structure mimics that of a natural neurotransmitter. In fact, these drugs spate 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. other drugs, such as amphetamine, cause nerve cells to release prodigal amounts of natural neurotr ansmitters 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 going away 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 reckon the brains advantage circuit, which is part of the limbic system. Normally, the reverberation circuit responds to pleasurable experiences by releasing the neurotransmitter dopamine, which creates feelings of pleasure, and tells the brain that this is something ! crucialpay attention and hark back it. Drugs hijack this system, create unusually large amounts of dopamine to alluvion the system. Sometimes, this lasts for a farseeing 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.
