Biopsychology, Global Edition, 11th Edition by John P.J. Pinel and Steven J. Barnes provides an engaging introduction to the biological foundations of behavior and mental processes. The book examines how the brain and nervous system influence perception, emotion, learning, memory, sleep, motivation, neurological disorders, and psychological health. It covers the anatomy of the nervous system, neural conduction and synaptic transmission, research methods in biopsychology, sensory systems, motor control, brain development, hormones, genetics, lateralization, and neuroplasticity. This edition also expands discussion of emerging topics such as epigenetics and consciousness while integrating clinical case studies and real-world examples throughout the text. Designed for psychology, neuroscience, and behavioral-science students, it helps readers connect biological mechanisms with human behavior and understand how modern neuroscience investigates the relationship between the brain, body, and mind.
