Figure 3From: White versus gray matter: fMRI hemodynamic responses show similar characteristics, but differ in peak amplitude(a) Hemodynamic response function (HRF) data (arbitrary units; AU) for the raw isolates (n = 8 averaged). The horizontal axis depicts time in TRs (2 second repetition time). Data were extracted from ROIs in the corpus callosum, cingulate, and parietal areas. (b) HRF data (AU) for the finite impulse response analysis from all three ROIs. All other details as per Figure 3a.Back to article page
