Single Trial Simulated Data




Elekta Neuromag Vectorview (306 channels), Subject #1


Four cortical sites were activated for this simulation of a visual working memory task: 1) V1; 2) inferior lateral occipital gyrus (I.LOG); 3) IPS; and 4) dorsolateral prefrontal cortex (DLPFC). The cortical patch current strengths were assigned values similar (15-66 nAm) to what we find in our studies, using the MRIVIEW Forward Simulator. Patch strengths were then randomly jittered about those values by up to +/- 50% across the single trials. Peak latencies were jittered across each trial by a randomly selected value up to +/- FWHM/2.
100 single trials, along with the average of those single trials in:

The same active areas as above, with the addition of oscillations; Gamma band oscillations added to v1, IPS, amd ILOG; Beta band oscillations added to IPS and DLPF.
