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 |
