Document Summary
Colors only the soma and different parts inside it (rna, ribosomes, etc. ) Broadman used nissl stain to do broadman"s areas, to determine the brain has cells of different structure. Only produced the syllable tan , although comprehension was good. Post-mortem exam revealed lesion in inferior frontal cortex. Are associated with language production (broca"s area) Hippocampus damage, unable to create new memories. Damage to the hippocampus, unable to create new memories. Electrodes stimulate one part of the brain to see what it does. How penfield map was created, mapped out motorisensory homunculus. Em radiation (direct measure of brain activity) Measures the difference in voltage between inside and outside. Electrical field created by neurons is detected by gyri of cortex. The fields are perpendicular to the cortex. Records data from a lot of cell, good temporal resolution, bad spatial resolution. Uses: distinguishing epileptic seizures, characterize seizures for treatment, test for. Brain dead , if in a coma, monitor the effects of anesthesia.
