Assigned neurotransmitter: Dopamine
1. Write a 3-5 sentence paraphrased summary of the assigned
neurotransmitters' purposeand function
Dopamine is a monoamine neurotransmitter in the brain that acts as a
chemical messenger between the nerve cells of the brain and the rest of
the body.
Dopamine plays a role in the “reward center” of the brain and in
other functions such as movement, memory, pleasure and reward,
motivation, attention, sleep, mood, and learning. It is often referred to
as the “feel-good” neurotransmitter as it gives a sense of pleasure
, and the motivation to do something when experiencing the
pleasurable feeling. As part of the “reward system”, it is thought that,
from an evolutionary standpoint, dopamine provides a good feeling
as a reward for doing things necessary for survival such as eating,
drinking, reproducing, and competing for survival. When a person
does something perceived as pleasurable, a large amount of
dopamine is released from the brain causing the “feel good” feeling
that causes you to seek more of that feeling, something that may play
a role in addiction (Cleveland Clinic, 2020).
2. Link dopamine to a psychiatric diagnosis
