Document Summary
Some send signals to our senses, others send them to our motor apparatuses: the brain isn"t just a tunnel for neurons. 300 billion stars in the milky way galaxy: you have 100 billion neurons. Third birthday: you solved it in your head when you sang it to yourself, when you listen to something else, it"s hard to sing to yourself. People have experimented crudely frontal lobotomy: detaches frontal lobe and decreases anxiety. Shows how luxuries get added to necessities: the forebrain and its cortex frontal lobe, temporal lobe, parietal lobe, and occipital lobe. Parietal lobe on the back top: where things are in space, spatial thinking, damage can cause spatial neglect ignoring the left side of something a model of clock is only copied with the right half. Somatosensory cortex sensitive and taking information: hands mostly, and tongue and feet. If you learn braille, your somatosensory cortex devotes more to the fingers.
