Indeed, the brain has many devious tricks for ensuring that the irrational act of taking drugs, deemed "good" because it enhances dopamine, will be repeated. pet-scan images taken by Volkow and her colleagues reveal that the absorption of a cocaine-like chemical by neurons is profoundly reduced in cocaine addicts in contrast to normal subjects. One explanation: the addicts' neurons, assaulted by abnormally high levels of dopamine, have responded defensively and reduced the number of sites (or receptors) to which dopamine can bind. In the absence of drugs, these nerve cells probably experience a dopamine deficit, Volkow speculates...
...PET-SCAN images of the brains of recovering cocaine addicts reveal other striking changes, including a dramatically impaired ability to process glucose, the primary energy source for working neurons. Moreover, this impairment--which persists for up to 100 days after withdrawal--is greatest in the prefrontal cortex, a dopamine-rich area of the brain that controls impulsive and irrational behavior. Addicts, in fact, display many of the symptoms shown by patients who have suffered strokes or injuries to the prefrontal cortex. Damage to this region, University of Iowa neurologist Antonio Damasio and his colleagues have demonstrated, destroys the emotional compass...
