Neurosurgical mapping (1850-1980)- lay wires on top of brains during someone"s brain surgery in order to find which parts of the brain make things happen (can be used to find which part of brain is epileptic center) Electroencephalogram (eeg)-hairnet with sensors which senses dendritic potentials. Mri almost always don"t show alzheimer"s fmri diffusion tensor imaging links one area of brain to another and shows pathways between the two forebrain, midbrain, hindbrain. Cerebellum (means little brain) like a cauliflower: inner cerebellum old cerebellum. Balance, linked to semicircular canals of ears, and trochlear nerve that moves the eyeballs. Damage causes cerebellar ataxia (drunk people walk) Pons (means bridge, bridge of left brain controls right side) and medulla (means heart: protective reflexes vomiting/reverse peristalses, coughing/tussis, sneezing/sternutation. Sneezing and coughing are the fasted movement the human body can do. Babinski reflex (foot gets lightly touched, toes spread and curl down)
