Document Summary
50% of cortex that penfield wanted to look at, he couldn"t sulcus (can"t get to it); restricted to surface. Face representation in humans is inverted (area representing chin is higher than area representing forehead). V1: moving vs. stationary images = v1 treats them as the same thing fires at moving and stationary dots. Mt: moving vs. stationary = doesn"t respond to stationary dots, cares only about motion. Event-related fmri study showing memory failure as a problem of encoding. Standard task present people with simple words, one every 3sec (e. g. ) You use single events image bold response when they"re seeing the word. Next, write down as many words as you can remember (usually about 30-40/100). If you look at bold response (signal change %) when they"re seeing each of the words, you can predict which words they"re going to forget and which words they"re going to remember.
