Standard Error (SE). Positive numbers indicate that right centrotemporal spikes induce a greater increase in connectivity from baseline than left centrotemporal spikes; negative numbers indicate that left centrotemporal spikes induce a greater increase in connectivity from baseline than right spikes.
*
Indicates that right and left spikes have significantly different effects on connectivity after Bonferroni correction for multiple comparisons (p < 0.0026).
#
indicates that the differential impact of right vs. left spikes on connectivity trends toward significance after Bonferroni correction (p <0.005).
