Document Summary
Cerebellum involves in sensory motor integration. Medulla responsible for basic life processes. Taking sensory information to integrate motor information. Reticular formation controlling sleep/wakefulness cycle (circadian rhythm) Involve the most basic aspect of the circadian rhythm. Hypothalamus hormone regulation, hunger/thirst behavior, territoriality (fight their territory), sexual behavior. 4f finding, feeding, fighting, and fucking (sexual reproduction) Cerebral cortex (neocortex) the most evolved part of the human brain. Limbic system system for emotion and emotionality. Emotionality is a big component for human for emotional repertoire. Nuclei formed in the anterior portion of the nervous system form the brain. The more intelligent the species, the larger the cortex for the species. However, it need to be compared for brain size and body size. Human is number 2, while dolphins have the largest brain relative to their body size. The size of the brain structure is directly related to the function to that particular species.
