This episode explores biopsychology, the field that studies how biology shapes the mind and behavior. It explains how the nervous system works, from the central and peripheral systems to the role of neurons and neurotransmitters like dopamine, serotonin, and acetylcholine. The episode highlights how brain regions—from the frontal lobe to the limbic system—govern decision-making, memory, emotions, and survival functions.

We also look at the endocrine system, showing how hormones like cortisol, oxytocin, and adrenaline influence stress, bonding, and energy. Genetics and epigenetics are discussed, emphasizing the interaction of heredity and environment in shaping traits and mental health. Everyday applications include understanding addiction, depression, stress, and memory disorders.

The central message: mind and body are inseparable. Every thought, feeling, and action has a biological foundation, and by studying it, we open doors to deeper understanding and better treatments for psychological challenges.
