Document Summary
To see a tumor - should use an mri. Hippocampus in charge of memory and emotions. Cortex (occipital lobe) vision problems: primary motor cortex in charge of motor. Both mri and ct scans structural imaging. Mri very precise, detailed picture of the brain. Ct relatively quick, inexpensive, picture of the brain. Pet and fmri functional imaging used to learn how brain function relates: pet uses invasive radioactive tracers fmri non-invasive. Eeg and single cell recording are similar electrodes are used to measure: eeg measures of electrical activity of a population of neurons. Find part of brain responsible for speech production. Invasive often used in animals not in humans: single cell recording - measures electrical activity of a single neuron to cognitive tasks brain activity. Corpus callosum is severed find it in a pile of pictures; does not travel to the right hemisphere.
