The goal of this set of readings is to hopefully answer the following two questions:
1. How focal to the ATL is the atrophy in semantic dementia?
2. Do semantic deficits correlate specifically with atrophy or hypoperfusion in the ATL?
The answer to these questions will determine how strong the evidence is regarding the link between semantic deficits and ATL dysfunction.
I've included a bunch of papers because I'd like to get as complete a picture as we can. But no need to rush through all of them this weekend, as our next class meeting isn't until Jan. 28th. In the meantime, if I've left off any critical papers, please send me a note, either on- or off-line. I've already heard from Murray Grossman's group (via Jonathan Peelle) in this respect, and this led me to some interesting papers. Any suggestions from the London Group? I noticed a couple of hits from UCL, so I know someone over there is watching... Would very much like input from all the SD experts!
