In this week’s videos and papers we discuss the role of biological factors – nature – in the development of mental health problems. We hear again from Professor John Quinn, who outlines some ways in which neurotransmitter activity affects our moods, and is itself affected by events.

To understand at least a little of how biological factors influence our mental health and well-being, you’ll need to read the papers and scientific journal articles (unless you’re already an expert).
