Biological Basis of Behavior: Introduction to Biopsychology

How does a physical organ like the brain generate complex thoughts, emotions, and behaviors? Understanding the biological underpinnings of the mind is essential for anyone studying psychology, neuroscience, or human behavior. This course guides you through the biological systems that govern human action. You will move from foundational cellular concepts to the complex neural networks that drive memory, emotion, and perception, gaining a clear scientific perspective on how the physical body influences the mind. What you will learn: Understand the structure and function of neurons, neurotransmitters, and synapses; Map the major divisions of the nervous system and the functions of key brain regions; Explore the endocrine system and how hormones regulate stress, growth, and behavior; Analyze the role of genetics and evolutionary psychology in shaping individual differences; Examine modern neuroplasticity and how environmental factors physically alter brain structure; Discover contemporary research areas, including the gut-brain axis and its impact on mental health. Starting with essential terminology and the anatomy of a single nerve cell, this text-only course systematically builds your knowledge up to complex behavioral systems and modern cognitive science. It is designed for beginners, psychology students, and curious learners with no prior background in biology or neuroscience. Start reading today to uncover the biological mechanisms behind why we think, feel, and act the way we do.
