Figure 1. Magnitude of signal to noise ratio at stimulus frequency in GM and WM.

Figure 1.

(A) The normalized ratio of GM signal magnitude to noise at stimulus frequency (0.025Hz) overlaid on anatomic images. Rows refer to signal magnitude at 4, 8 and 12 Hz on three representative slices containing BA17&18. Color scale represents the variation of subject averaged normalized signal at stimulus frequency (>0.3). (B) Similar WM map overlaid on anatomic images to compare signal magnitudes.
