Basic Concepts

Biological Bases of Behavior

How Does the Body Influence Behavior?

Our brains and bodies work together to shape everything we do, from reflexes to emotions.

The Nervous System

  • Central Nervous System (CNS): The brain and spinal cord.
  • Peripheral Nervous System (PNS): All nerves outside the CNS.

The Brain

  • Cerebral Cortex: Controls thinking, memory, and decision-making.
  • Limbic System: Handles emotions and motivation.

Neurotransmitters

Chemical messengers like dopamine and serotonin influence mood, movement, and learning.

Genetics

Inherited traits can affect intelligence, personality, and even vulnerability to mental disorders.

Everyday Impact

Understanding biology helps explain mental illnesses, brain injuries, and how substances like caffeine affect us.

Examples

  • A person feels happier after exercising due to increased endorphins.

  • Brain scans reveal changes in someone with a concussion.

In a Nutshell

Behavior is influenced by the brain, nervous system, and genetics.
