Fig. 1 Arrangement of optical fibers of the OT and measurement channels over the occipital and frontal cortex of infants. Pathophysiology 2004 10, 277-281DOI: (10.1016/j.pathophys.2004.01.022)

Fig. 2 Hemodynamic response to the visual stimulation. Epoch-averaged time series of [oxy-Hb] (solid line) and [deoxy-Hb] (dash line) at channel 12 of the occipital cortex and channel 13 of the frontal cortex are illustrated. Zero second of each panel is set at 1s after the termination of the stimulation. The unit of [oxy-Hb] is a relative change from an arbitrary zero baseline at the start of the measurement period. (a) Occipital activation; (b) occipital and frontal activation; (c) frontal activation. Pathophysiology 2004 10, 277-281DOI: (10.1016/j.pathophys.2004.01.022)

Fig. 3 Locations of significant changes in [oxy-Hb] that were consistently observed among the subjects. The relative size of each circle represents number of the subjects who showed significant changes (P<0.01) at the corresponding channel.
