MELINA UNCAPHER - this was quite a good talk ... worth hearing again.

she is now at Anthony Wagner's Lab... the Stnaford Memory Lab.

was a PhD student here.  ? then was at UC Irvine.

Anthony did a famous  1998 paper in Science with Randy Buckner on  Subsequent Memory.

present  Lion    Rock    Lamp    Monkey

            remem  forgot   rem        forgot

now look at what was happening at the time of presentation to look for correlates of

remembering vs forgetting (failure ot encode).

the remembering is all done in the medial temporal lobe  (hippocampus).

There are two attentional networks.

1) The DORSAL ATTENTIONAL Network  works with the FEF  frontal eye field

and is the TOP_DOWN attentional network  (voluntary attention)

this is  above the IPS  (intraparietal sulcus).

This is what is working when your studying a book or reading on your screen.

2)  The VENTRAL ATTENTION NETWORK is the reflex netowrk

say, your name is called or otherwise distracted and you re-orient.

fMRI...   are there parietal encoding effects that correlate with items that are remembered or forgotten.

YES.    Items are remembered when there was doral parietal activity  (top=-down attn).
