- 1. Psychobiology, also known as biopsychology or behavioral neuroscience, is a field of study that examines the relationship between behavior and biology. It explores how the brain and nervous system influence our thoughts, feelings, and actions. Psychobiologists investigate topics such as brain development, the role of neurotransmitters in behavior, and the effects of stress on mental health. By studying the biological underpinnings of behavior, psychobiology helps us better understand various aspects of human cognition and emotion.
