SUMMARY:Towards a whole brain account of decisions for actions using high 
 precision MEG - Sven Bestmann\, University College London

CONTACT:Paula Kaanders
DESCRIPTION:The physiological mechanisms through which our decisions are t
 urned into actions still remain largely undetermined. I will present some 
 ongoing (and preliminary) work that leverages our recent advances in high-
 precision MEG (hpMEG) and promises to shed new light on this problem. I wi
 ll focus briefly on the approach we employ for hpMEG\, and show that this 
 in principle allows for reliable assessment of deep (thalamic and BG) sour
 ces – a key requirement for fully understanding decision to action trans
 formations. I will then present data showing how high and low frequency os
 cillations map onto deep and superficial cortical laminae during simple se
 nsorimotor decisions\, and furthermore scale with the degree of expectatio
 n about the forthcoming action.
