Based on some pilot data, we focussed on two general areas:
the ventral occipital lobe, which contains some of the visual processing regions that are controlled by attention,
and parietal lobe, which is associated in general with shifting and maintenance of attention.
The detailed anatomy of the parietal lobe varies a great deal from person to person.
A common procedure in fMRI is to take individual brain images and stretch them onto a standard template before making comparisons.
The activations that we're looking for are very subtle, and we were concerned that if they were subjected to such spatial averaging they'd be blurred out.
