Parts of the brain
| Term | Definition |
|---|---|
| Brainstem | Automatic survival functions; begins where spinal cord swells |
| Medulla | Heartbeat, breathing; base of brainstem |
| Reticular Formation | Controls arousal; nerve network in brainstem |
| Thalamus | Directs/transmits messages to cortex from cerebelum/medulla |
| Cerebelum | "Little brain", coordinates voluntary movement/balance; base of brainstem |
| Hippocampus | Memory; Limbic system |
| Amygdala | Emotion; two almond-shaped clusters, Limbic system |
| Hypothalamus | Eating, drinking, body temp, linked to emotion; below thalamus, connected to pituitary gland, Limbic system |
| Cerebral Cortex | Ultimate control center/information processing center, linked with choice/humanity; intricate fiber, covers cerebral hemispheres |
| Glial cells | Protect neurons, support/nourish neurons |
| Frontal lobes | Speaking, muscle movement (motor cortex), planning/judgment (individuality); Cortex |
| Parietal lobes | Sensory cortex receives visual information; Cortex, behind frontal lobes |
| Temporal lobes | Auditory perception; Cortex, lateral portion of brain |
| Occipital lobes | Receive visual information; Cortex |
| Motor cortex | Voluntary movement; Cortex, rear of frontal lobes |
| Sensory cortex | Registers/processes sensation; Cortex, front of parietal lobes |
| Association area | "Uncommitted" area of cortex |
