Okay, I thought this was interesting, but I have no idea whether she's a zionist. I just didn't know where else to put this.

Nora Volkow in 2009.Nora Volkow (b. 27 March 1956) is director of the National Institute on Drug Abuse (NIDA). She is the great-granddaughter of Russian revolutionary leader and Head of the Fourth International, Leon Trotsky. Her father was the son of Leon Trotsky's elder daughter.[1]

Born in Mexico City, Volkow and her three sisters grew up in the house where Trotsky was killed.[1] She attended the Modern American School, then earned a medical degree from National University of Mexico before going to New York University for psychiatric residency. She chose a career in brain research after reading an article on the use of positron emission tomography in studying brain function. She did research at Brookhaven National Laboratory before becoming director of NIDA in 2003.[1]

[edit] ResearchShe has stated that her imaging studies of the brains of people addicted to drugs have helped to clarify the mechanisms of drug addiction. She also maintains that they have also helped to change the public's view of drug addiction, from that of a moral violation or character flaw to an understanding that pathological changes to brain structure make it very difficult for addicts to give up their addictions.[1] Volkow says that she has shown that abnormalities in the prefrontal cortex of addicts create a feeling of need or craving that addicts know is irrational but cannot prevent. Prefrontal abnormalities also make it difficult to override compulsions to take drugs by exercising cognitive control. The main areas affected are the orbitofrontal cortex, which maintains attention to goals, and the anterior cingulate cortex, that mediates the capacity to monitor and select action plans. Both areas receive stimulation from dopamine centers lower in the brain. A steady influx of dopamine makes it difficult for addicts to shift their attention away from the goal of attaining drugs. It also fastens their attention to the motivational value of drugs, even though these drugs have long stopped providing pleasure. It is now understood that dopamine activation does not signal pleasure. Rather, it signals the importance or relevance of sought-after goals. Addicts have a hard time turning their attention —and their actions— away from the goal of acquiring and consuming drugs. They are caught, she states, in a vicious circle of physical brain changes and the psychological consequences of those changes, leading to further changes.
