The study of the correlation between biological and psychological health is known as behavioral neuroscience, biological psychology, psychobiology or biopsychology. Often, behavioral neuroscience research projects are centered on animal models, which are used to emulate potential human responses. Human subjects are also used to test hypotheses.

Genetic, environmental and developmental mechanisms are all taken into account as behavioral neuroscientists create experiments and analyze results. Reliable data is obtained by manipulating a particular attribute within a living subject or in an experimental atmosphere. The living subject's reaction to the change, whether it is internal or external, is measured, and the results are evaluated.

Electrical, chemical and magnetic stimulation are all used during biopsychology research projects. Quite often, test subjects' reactions are measured and recorded via EEG, fMRI, single-unit or multielectrode recording techniques.

By investigating the relationships between physiological and psychological responses, psychologists and scientists gain a greater understanding of human pathology as a whole. In turn, more extensive comprehension leads to advancements in evidence-based practice and also to the development of better treatment options.
