Understanding the Connection Between Brain and Behavior

The biological bases of behavior focus on how our brain, nervous system, and body influence everything we think, feel, and do. This area explores the intricate workings of neurons, neurotransmitters, and the structure of the brain.

Key Concepts

• Neurons: The building blocks of the nervous system, transmitting information through electrical and chemical signals.
• Neurotransmitters: Chemicals like dopamine and serotonin that help neurons communicate.
• Brain Structures: Regions such as the hippocampus (memory formation), amygdala (emotion), and frontal lobe (decision-making).

Real-World Impact

Understanding biological bases can explain why people react differently to stress, why some develop mental illnesses, and how medications like antidepressants work.
