Understanding the Link Between Neural Activity and Immune Function

This chapter investigates the intricate connections between neural activity and immune function, drawing on insights from both neuropsychology and psychoneuroimmunology. A better understanding of the role of the brain and mental health in regulating immunological responses and general wellbeing is the overarching goal. In order to determine the role of neuronal circuits and neurotransmitter systems in controlling emotional reactions and stress, we begin by going over basic ideas in neuropsychology. This chapter delves into the ways in which these brain systems influence immune function, incorporating insights from psychoneuroimmunology. It examines the mediating functions of neurotransmitters and hormones in the immune system's response to stress, among other topics. The consequences of mental health issues on immunological function, including persistent stress, anxiety, and depression, are highlighted in particular. We highlight the two way nature of the connections by discussing how changes in immune function might impact brain activity and mental health.
