Biopsychology aims to uncover explanations for behavior through brain activity, the nervous system, physical factors, genetic makeup, the endocrine system, bio-chemistry, and evolution (Robins, Gosling & Craik, 1999).

He pioneered the study of anatomy and based on animal observations and vivisection, was able to identify and describe cranial nerves.

These ideas were later challenged and altered by philosophers and psychologists who were at the forefront of the development of biopsychology. Theorists of Biopsychology
