Psychobiology explores the intricate relationship between biological processes and behavior, emphasizing how the brain, nervous system, hormones, and genetics influence psychological functions such as perception, emotion, learning, and memory. The course bridges foundational principles of biology with core concepts in psychology, offering an interdisciplinary perspective on topics like neural communication, sensory systems, motivation, and mental health disorders. Through a combination of theoretical frameworks and empirical research, students gain a comprehensive understanding of the biological bases underlying human and animal behavior.
