[B002] Permutation: starting from MT+? @220 ms ==> right IPL @250 ==> left IPL @ 280

Aligned to Event B 

(speed change onset)

The permutation test for the glass brain should be done by Monday noon for the event of B, A002 (GO cue) and C (key down), then the permutation threshold for each time slice will be used to search activation peaks in Tal. space for all the three events.

Correct Trials

@220 ms activation at left MT+

250 ms peak reported at right IPL

@280 ms, left IPL

 

Error trials 

at the same time slice

@220 ms

@230 ms

@250 ms

@280 ms

[A002] Permutation: 40 ms after "Go" cue, parietal and frontal activation

All the averaged figs shown here are based on both left and right visual field display.  The label at the bottom of the fig indicates the event of interest (e.g. A002), the condition(correct or error), the time slice(2240 ms)

Note: A002 event (GO cue, the stimulus offset) always happens 2200 ms after the stimulus onset.

Robust right IPL, and possible interaction between bilateral premotor regions,

 

error trials: IPL activation moves around

Right premotor activated again @ 170 ms after GO, but correct trials has precuneus (KO?) activation.
