Research

Answer 1

McNeal and Cimbolic found that serotonin was linked to depression because it played a role in stabilising our mood. Countless drug trials have shown the link between serotonin and mood.

Question 2

Applications

Answer 2

Antidepressants are being used to treat millions of people. They are made possible due to our understanding of the role of serotonin in mood regulation.

Question 3

Weaknesses

Answer 3
