Recommended: Using research evidence, critically discuss the role of the neurotransmitter dopamine upon behaviour

Dr. Nora Volkow from National Institute on Drug Abuse (NIDA) explains why dopamine is a powerful chemical and how it triggers the brain to want substances such as cocaine more. One thing that had me shocked about the way the neurotransmitter dopamine works was compared to food, dopamine never decreases when one consumes drugs such as cocaine. Dr. Volkow explained how food can be presented in front of you after being hungry for some time which makes dopamine increase, but once we are eating, the dopamine decreases therefore one does not want the food anymore. Now, when it comes to drugs such as cocaine, dopamine increases but never decreases therefore they want it more, which then leads to addiction. This meaning that a person can no longer

  • Drug Addiction: A Brain Disease?

    746 Words  | 2 Pages

    Drugs seem to cause surges in dopamine neurotransmitters and other pleasure brain messengers. However, the brain quickly adapts and these circuits desensitize, which allows for withdrawal symptoms to occur (3). Drug addiction works on some of the same neurobiological mechanisms that aid in learning and memories (3). "This new view of dopamine as an aid to learning rather than a pleasure mediator may help explain why many addictive drugs, which unleash massive surges of the neurotransmitter in the brain, can drive continued use without producing pleasure-as when cocaine addicts continue to take hits long after the euphoric effects of the drug have worn off or when smokers smoke after cigarettes become distasteful."

    ...ts the amount of dopamine receptors that are available, which in return diminishes the functions of the reward circuit. They are compelled to abuse drugs to bring their dopamine function back up to normal, which inquires a larger amount to achieve the normal dopamine high (this can be defined as tolerance). There are many changes in neurotransmitters other than dopamine. Long-term drug abuse causes changes in other parts of our brain chemical system, for example the glutamate which is a neurotransmitter that influences the ability to learn and again it influences the reward circuit. When the optimal concentration is altered by the drug abuse the brain tries to compensate which can cause impairment in cognitive functions. One must remember that changes areas of the brain that are critical such as our judgment, memory, learning, behavior control, and decision making.
