• Write analysis that combines across hemispheres.
• Sort out mauro's retinotopy
• Write stimulus program for orientation task
• Stimulus program for popout threshold
• Train subject on task - collect psychophysics data

First experiment run. Ran two distractor contrasts (0.1 and 1) and 3 target contrasts (0.1 0.5 and 1) with target on either location. Hoping to maybe see that at high target contrast, that responses for low contrast pop-out stimulus would show a large response in V4 but not other areas. Didn't really find this, but found that the distractor response was modulated by the patch on the opposite side.

Analysis done with _every_ stimulus and then shown with spatconPlot.

Here is the r^2 map. Note that the ROIs that Mauro made don't seem to project correctly onto the surface. Also the data appear to modulate with contrast only in one half of cortext (left side), which probably means there is some problem with the alignment for the right side.

Here is a single voxel's spatconPlot which shows the effect

Here are two oddball ROI's:

Here are two distractor ROI's:

Ran 3 contrasts on the target (either on left or right). Contrasts chosen to be equal log units away from he distractor contrast of 0.5. One higher contrast (0.85) and two lower contrasts. Also ran the spatcon localizer. Spatcon localizer was run with too many volumes (200 instead of 168) but worked fine once the appropriate frames were dropped.

Analysis was done using event-related processing setting stimulus type to “_every_” and then displaying with spatconPlot

Didn't check left side very much since I didn't have the ROIs.

Here is one for the target:

and one for the distractors:
