Document Summary
Karl ashley and the engram trained rats and picked at their brains (lesions) until he saw when they forgot their training i. The rats never forgot anything until he took about 40% of the brain out. It didn"t matter which of the parts he took out, the rat still forgot- law of mass action a) Memory is distributed along the brain, there is no set place b. Brenda did somethings with this dude named henry mollison who suffers from epilepsy (inhibitory neurons don"t do their jobs) Dude named dr. scoville- says that his seizures originate from his temporal lobe so he takes out the temporal lobe. Henry remembers everything except for his immediate memory. He knows that he"s going to have surgery, but after the surgery occurs he has no problem recalling things from right before the surgery. But he has no ability to make new long term memory c. Retrograde amnesia- can"t remember anything about right before the accident.
