Figure 3. The inter-hemispheric coherence of the oxy-hemodynamic fluctuation.

Figure 3

Coherence values were calculated from 0.01 to 0.10 Hz with a spectral resolution of 0.01 Hz. (a) In the oxy-hemodynamic fluctuation, there was a significant difference between ASD and TD children at 0.02 Hz (df = 28, t = −3.59, P = 0.0012). (b) In the deoxy-hemodynamic fluctuation, there were no significant differences between the ASD and TD groups at any frequency point. ASD, autism spectrum disorder; TD, typically developing.
