| A | B |
|---|
| brainstem | oldest part of brain; spinal cord swells; automatic survival functions |
| medulla | base of b-stem; controls breathing and heartbeat |
| reticular formation | nerve network; controls arousal |
| thalamus | sensory switchboard, located above b-stem; directs messages to cortex |
| cerebellum | "little brain" rear of b-stem; coordination |
| case study | study single person or situation |
| CAT scan | x-ray photos taken from different angles |
| MRI | uses magnetic fields and radion waves produce images; see structures within brain |
| EEG | recording of waves; help evaluate brain function |
| PET scan | visual display of brain activity detects a radioactive form of glucose |
| Limbic system | ring structures form border brainstem and cerebral crotex regulates important functions |
| hypothalamus | under thalamus; directs maintenance activities |
| hippocampus | neural center; processes memories for permanent storage |
| amygdala | two almond-shaped structures; linked to emotions |
| cerebral cortex | fabric interconnected neural cells, body's control and process center |
