Dopamine and Drugs
Dopamine
By: Jade Allen
What is Dopamine?
The Impacts of Dopamine on Society
Dopamine impacts society in both positive and negative ways.
What Does Dopamine Do?
Dopamine is a neurotransmitter responsible for motor behaviors, such as moving your arms or walking, and also for your ability to engage in rewarding tasks. When you preform a task that your body perceives as good your dopamine transmitters send pleasure signals to your brain that make you feel good about the decision you made.

Dopamine and Your Body
Improper levels of dopamine can take a toll on an individuals body. The major disease that is directly linked to low levels of dopamine is Parkinson's Disease. When dopamine levels are too low they cause the individual to shake and become weak and confused with Parkinson's Disease the individual loses a lot of control over their body. Other major disorders associated with dopamine are schizophrenia, psychosis, and ADD.

I thought this was a cute way to look at how your body reacts to signals of dopamine after repetition!

The Neurotransmitter Dopamine, discovered in Sweden in 1952, is used by the brain to stimulate motivation and to give the body a sense of reward. When dopamine is released into the brain it makes you feel pleasure or satisfaction with any task that you have just preformed. Dopamine is also heavily related to drug addictions because when using drugs it enhances your levels of dopamine which causes a euphoric feeling.

I have always been a highly motivated person. I feel like my dopamine levels help me pursue my dreams and goals. Without the proper amounts of dopamine I would not be motivated to perform my everyday tasks.
My mother does suffer from depression which has been linked to low levels of dopamine. Her depression has also led to many addictions. She becomes addicted to things to stimulate the dopamine she is not receiving. Having to grow up around this
has been very hard on me.
Cocaine is one of the most notorious drugs when discussing dopamine. The reason cocaine is so addictive is because when used it takes away dopamine's ability to recycle itself. Cocaine creates a block in the dopamine transmitting nueron that would regularly recycle the dopamine for a later use. When blocked the dopamine builds up causing a greater feeling of pleasure. Once the cocaine wears off the user is left with nothing and has a sense of longing for that same feeling of euphoria which creates their cycle of addiction.
Dopamine relates to behavior
because it affects emotion very directly. Dopamine is the driving force behind both goals and motor behaviors. When we do something that our body believes is good it will make dopamine transmitters send us a "congratulations" of sorts. This positive reinforcement makes us want to do those same tasks again.

The same is true about depression. When we are not receiving the proper amounts of dopamine for a task we have preformed it can cause us
to feel depressed or upset.

Dopamine and Your Behavior
This neurotransmitter also has some medicinal purposes! For example, dopamine can be put into a patients blood stream to act as a diuretic, increase kidney output or even raise blood pressure.

Dopamine Used for Treatment

(Adelson, 2005)
Dopamine plays a large roll in terms of thought and feeling. With your previous knowledge that something you do will increase your levels of dopamine (or make you happy) you will be thinking about when you can do that task again in order to feel that pleasure. A lot of the time this leads to addiction because an individual wants that feeling so bad they continue to repeat that action continuously so that they always feel the pleasure. However, the result of repeating the action again and again causes your body to not be so excited about it which results in a less intense rush each time.

Dopamine and Your Mind
Gambling is one task that many people can preform over and over yet still get the same amount of high dopamine levels each time. This phenomena is because the individual is partaking in a risk yet there is no guarantee of reward each time. This variability makes the experience enthralling and addicting.
