Biological psychology, or biopsychology, is a field in which the mind-body connection is explored through scientific research and clinical practice.
Defining Biological Psychology. Alternative names of biopsychology, such as behavioral neuroscience and physiological biology, indicate a preliminary definition. Researchers in this field examine not only how biology-particularly the nervous system-affects behavior, but also how behaviors affect the brain.They conduct experiments, often using lab animals as a model for humans, to explore the interactions between the environment, behavior and physiology.esearchers in this field examine not only how biology-particularly the nervous system-affects behavior, but also how behaviors affect the brain.
