| Basal ganglia (nuclei) | cognition, motor control (initiating and monitoring movements, inhibit antagonistic or unnecessary movements) |
| Cerebellum | coordiantion and balance |
| Thalamus | gateway to the cerebral cortex, mediates sensation, motor activities, cortical arousal and memory, sorting out and editing information |
| Hypothalamus | autonomic control center, emotional response and behavior, body temperature, food intake, water balnce and thirst, sleep-wake cycles, endocrine system functioning |
| Corpora quadrigemina | nuclei that corrdinate head and eye movements, auditory relay, startle reflex |
| Cerebral peduncles | pyramidla motor tracts descending toward the spinal cord, tracts connecting the midbrain to the cerebellum |
| Pons | conduction tracts, pathway between higher brain and centers and the spinal cord, cranial nerves, respiratory rhythm |
| Medulla oblongata | heart beat, blood pressure, respiration |
| Limbic system | fiber tracts and gray matter, emotions, feelings |
| Reticular formation | govern the arousal of the brain as a whole, sensory input filter, muscle tone, coordination, autonomic centers, extend through the medulla, pons and mid-brain |
