This "neuroscientific revolution," with its focus on the biological basis of behavior, has led to several mental illnesses now being considered as physical disorders resulting from malfunctions and / or malformations of the brain. That some behaviors and psychiatric illnesses can be traced to biological causes does not imply that psychosocial and sociocultural influences are totally discounted. For example, there is evidence that psychologi,cal interventions have an influence on brain activity that is similar to psychopharmacologic intervention (Furmark et al., 2002), and evidence exists that lifestyle choices, such as marijuana use, can precipitate mental illness (psychosis) in individuals with genetic vulnerability (NIH, 2015). Ongoing research will build a better understanding of the complex interplay of neural activities within the brain and in interaction with one's environment. The systems of biology, psychology, and sociology are not mutually exclusive-they are interacting systems. This interaction is clearly indicated by the fact that individuals experience biological changes in response to various environmental events. Indeed, one or several of these systems may, at various times, explain behavioral phenomena. This chapter focuses on the role of neurophysiological, neurochemical, genetic, and endocrine influences on psychiatric illness. [Show More]
