Overview

Chemical formula for dopamine

As dopamine plays an important role which can affect people's memory, motivation, behaviour and cognition, the topic of dopamine's effect on decision making has been studied to gain a better understanding.

  Suggestions for this section:

  • Engage the reader with a scenario, example, or case study, and an accompanying image
  • Explain the problem and why it is important
  • Outline how psychological science can help
  • Present focus questions

What is dopamine?

edit

Dopamine is a chemical messenger, known as a neurotransmitter, working in the brain to help nerve cells transmit messages in the brain and the rest of the body. Dopamine plays a role in numerous body functions including: motivation, memory, attention and more (Health Direct Australia, 2023).

  • The Conclusion is arguably the most important section
  • Suggested word count: 150 to 330 words
