AP Psychology / Unit 1: Biological Bases of Behavior
1.4 The Brain
Notes
- Frontal lobe: planning, decisions; motor cortex. Parietal: touch (somatosensory cortex). Temporal: hearing. Occipital: vision.
- Limbic system: amygdala (fear), hippocampus (new memories), hypothalamus (drives, hormones).
- Brainstem: medulla (heartbeat, breathing). Cerebellum: balance, coordination.
- Broca's area (speech production), Wernicke's area (understanding).
- Neuroplasticity: the brain can rewire.
Practice
Damage to the hippocampus would most affect:
Memory formation.
Someone can understand speech but struggles to speak. Likely damage:
Speech production.
An fMRI shows:
Functional imaging.
