9 Long-term Memory The theory is that the MTL is temporally involved in declarative memory in normal humans…

13 functional imaging data from “normal” subjects confirms lesion studies be skeptical!

14 Long-term Memory What would it be like to possess the ability to remember everything?

15 Long-term Memory Case study of S. (Solomon Shereshevskii) Russian journalist never took any notes, recalled everything verbatim thought this was “normal”

23 What do you think the brain of someone that has this “super memory” would look like? Long-term Memory

24 What if I told you it looked like this? Long-term Memory Kim Peek

25 Long-term Memory macroencephaly no corpus callosum no anterior/posterior commisure degenerated cerebellum
