Join us on CSS Breakdown: Book by Book, Season 07, Episode 02, as we delve into Chapter 2 of Atkinson & Hilgard's 'Introduction to Psychology 15th Edition': 'Biological Foundations of Psychology'. In this episode, we'll journey deep into the human body to uncover the intricate biological underpinnings of our perceptions, experiences, and behaviors. Discover how our nervous system, from individual neurons to complex brain structures, processes information and regulates our actions. We will explore:

o Neurons and Neural Communication: The fundamental building blocks of the nervous system, including dendrites, axons, and terminal buttons, and how they communicate through electrochemical impulses called action potentials and chemical messengers known as neurotransmitters.

o Key Neurotransmitters: Learn about the roles of vital neurotransmitters like acetylcholine, norepinephrine, dopamine, serotonin, glutamate, and GABA in various psychological phenomena, from memory to mood regulation.

o Brain Organization: A detailed look at the brain's main regions—the hindbrain, midbrain, and forebrain—and their specialized functions, including the central core, limbic system, and the highly developed cerebral cortex with its distinct lobes.

o Hemispheric Specialization: Understand how the left and right hemispheres of the brain divide labor for functions like language and spatial processing, and insights from split-brain research.

o The Autonomic Nervous System: Explore the sympathetic and parasympathetic divisions and their roles in arousal and rest.

o The Endocrine System: Uncover how hormones, secreted by glands like the pituitary and adrenal glands, influence mood, energy, and stress responses.

o Evolution, Genes, and Behavior: Examine the profound impact of natural selection, heredity, and genetics on our psychological and physical characteristics, including insights from selective breeding and twin studies. Tune in to unravel the complex biological machinery that shapes who we are.
