- Hippocampus
- Septal nuclei
What are the 3 different parts of the cerebrum (=forebrain)?
- Limbic system
- Cerebral cortex
- Basal ganglia
What are the overall 4 functions of the hypothalamus?
- homeostatic functions 2. emotional experience during high-arousal stages
- aggressive behavior
- sexual behavior
What are the 3 parts of the hypothalamus and their function?
- Lateral: hunger
- Ventromedial: satiety
- Anterior: sex, sleep (suprachiasmic nucleus), body temp
What are the 3 functions of the amygdala?

What are the 2 overall functions of the parietal lobe of the cerebral cortex?
- somatosensory processing
2. spatial processing
What are the 4 overall functions of the temporal lobe of the cerebral cortex?
- auditory processing
- memory processing
- emotional control
- language
What are the 2 parts of the brainstem?
The midbrain and the hindbrain
What is the role of the septal nuclei?
feelings of pleasure, pleasure-seeking behavior, and addiction
What are the 4 functions of the basal ganglia?
- Coordinate muscle movements
- Smoothen movements
- Maintain posture
- Routes info from the cortex to the brain and spinal cord
What is the role of the reticular formation?
Pain
What are the 3 functions of the pons?
- relays information between the cortex and medulla
- regulates sleep
- carries some motor and sensory info from the head and neck
What are the 4 parts of the hindbrain?
- Medulla oblongata
- Cerebellum
- Reticular formation
- Pons
What are the 3 functions of the medulla oblongata?

- Prefrontal cortex
- Motor cortex
- Broca’s area
What is the role of Broca’s area?
Speech production
What is the role of the occipital love of the cerebral cortex? What part of it carries this function (2 names)?
visual cortex=striate cortex: controls visual processing
