^#Significant difference from corresponding apical group (T-test; P < 0.05)

^*Significant difference from corresponding DUS group (T-test; P < 0.05)

^**Significant difference from corresponding DUS group (Chi-squared test; P < 0.05)

^†Significant difference in latency between groups (ANOVA; P <0.05), and no significant interaction

"E Points": recording sites on the gyrus that are responsive to ICES but not acoustic stimulation
