Biopsychology is a branch of psychology that explores the connection between biological processes and behavior. It examines how the brain, nervous system, hormones, and genetics influence thoughts, emotions, and actions. By studying these relationships, biopsychologists aim to understand how physical factors can affect mental health and behavior. Research in biopsychology often involves techniques like brain imaging and animal studies to investigate how different areas of the brain contribute to various psychological functions. This field helps bridge the gap between biology and psychology, providing insights into conditions such as depression, anxiety, and schizophrenia.
