Dopamine: a neurotransmitter responsible for stimulating the brain to create an urge for an action. These urges are typically followed by a feeling that triggers an action. We have a drop in blood glucose levels, resulting in hunger. We have an urge for sex we lust after our mate.
This ‘action’ is then rewarded with positive feelings of pleasure. We are thirsty, we then drink and now we feel satisfied. This creates a feeling of contentment or fulfillment.
When there is a breakdown in the brain and an individual isn’t able to have the neurotransmitter when it is needed it can be devastating. In the motor area of the brain it creates conditions such as Parkinson’s affecting the ability to create purposeful movements. When the higher brain functions are affected the result, although more subtle, might be to lose the urge for self-protection and take higher risks.
However, if too much Dopamine is present, the person my never feel satisfied once they have completed their ‘action’ and therefore are in a constant state of ‘desire’. This produces a constant hunger, or an inability to quench their sexual needs an anxiety that continues even when no threat is present.
Here is a graphic displaying the high and low levels of Dopamine and the effects that this Neurotransmitter can have on our body.
