Doing taking home exam right now, due on Friday...

[B002] Change onset, Correct vs Error activations

Download the comparison of activations after the change of speed (B002) for correct and error trials.

Movies avg for both left and right hemifield display

B002: speed change onset @ 0 ms, the change last 200 ms

Correct trials   vs.   Error trials

A002: GO cue @ 2200 ms, Stimulus onset @ 0 ms

Correct trials   vs.   Error trials

C002: Key pressing

Correct trials   vs.   Error trials

Comparison of correct and error activations

Will try to get individual glassbrain, and search for early premotor activation

After B (speed change)

 

After A002 (GO cue)

Early motor premotor response after speed change

Have stats class tomorrow, but will look at the permute_tfr program follow Paul's hint in the afternoon.  Try to fix the error in the code.


50 ms after speed change in correct trials, superior temporal activation, then @ 120 ms motor & premotor, parallel network the activation of motor response even before the change was perceived?  Need to look at individual data for this effect?

@ 210 ms

 

 @ 220 ms

@ 250 ms

@ 280 ms

Left Superior Temporal/IPL peak picked from 220 ms

Left SMC peak picked from 120 ms after B onset.  There is signal in Left SMC after the change onset, but power increase in error around key pressing are large -- can't get the induced TFR due to error in TFR plotting code.

[B] 230 ms after change onset, pre SMA (or ACC), lower band show powe difference

Correct trials glass brain img

A list of regions show activation after speed change onset

latency: ms


running TFR permutation, hope to be done by noon.
