Right ACC following B (speed change)- Change P = .01

R ACC (13 12  45)  mag. = 0.71   @230 ms






Look up



What is the lower resolutaion in time of the low freq domain... (previous figure)

------------------------

What is happening at the medial activation 60 ms - what is at medial/cingulate activation?
V. van Veen & Carter 2002: following impulsive errors (response made why stimulus evaluation is imcomplete), a large negative deflection (ERN, the detection that an error was made)
==> We did not exclude the correct trials that might be impulsive responses (small response latency)
Caudal ACC:
* frontalcentral N2 prior to the response on correct trials with stimulus conflict, 340 - 380 ms after onset. (response latency 450 - 500 ms)
* ERN immediately following error response (40 - 80 ms)

Rostral area of ACC:
* error related positivity peaking at 200 -250 ms following ERN


ACC is also strongly activated during "guilty knowledge" & "lies" 


Actually the medial frontal/ACC activation magnitude at 50 ms is higher (reported as superior frontal gyrus, more medial 2 voxel superior to the peak found at 60 ms, spatial resolution 2.5 mm):
@50 ms (-10 11 55) mag = 0.73
@60 ms (-18 10 50) mag = 0.68 








HBM - do  methods section...


Write abstract - than make figures that prove the story.
