MT+ location


Left MT+



 Right MT+

Problem: # 12 subject

sub#12 has noisy sensor data, but the beamformer reported good MT activation.




(-30    -68    1)



(-35    -66    -3)



Other subjects' RMS can be found here



Scatter plot: outlier sub#12 is in the black box






When sub#12 is excluded :




Individual virtual sensor time course at MT+, please look at sub#12:

Glassbrain movies

[A001] Aligned to [motion stimulus] onset
All movies are made with neurological orientation in Tal coordinates from onset (0 ms) of visual stim to 500 ms after onset.

AB

AK

CM
Left_Fast: weak MT+


DA
Left_Fast: interesting, contraL cuneus -> contraL V3A -> ipsiL MT+ -> contraL MT+


ES

JD
Left_Fast:contraL MT+ then moved to ipsiL MT+

PD
Left_Fast: V3A prior to V1 activation

SL

ST (this subject had no strong V3A activation)

SW
Right_Slow

SX

WW
Left_Fast: V3A prior to cuneus



[B002] Group avg for velocity change onset


[A002] Group avg for GO cue onset

[C] Group avg for button press
Incorrect response

Individual RMS plots for 9 out of the total 12 subjects

Bandpass: 1-30Hz
Motion stim onset: 0 s

In each subject, the first plot is left visual display and second plot is for right. 

Subject: AB



Subject: AK


Subject: CM

 Subject: DA



 Subject: ES



Subject: JD


Subject: PD


Subject: SW 


Subject: SX



There are two markers for the visual stim: (1) one is synchronized with the onset of the motion stim, (2) The second is synched with the onset of the velocity change, which is not shown here.
