Figure Lengend Snippet: Comparison of subthreshold and suprathreshold SEP. Grand average SEPs (n = 39 subjects) resulting from subthreshold (top) and suprathreshold (bottom) stimulation in EEG session 1. Time is expressed relative to stimulus onset. Gray shaded areas indicate significant differences compared with mean baseline activity (paired t test, Bonferroni corrected pBC < 0.0005, baseline: 200 ms segment prestimulus).

Article Snippet: Electrical finger nerve stimulation was performed with a constant-current stimulator (DS7; Digitimer) using single square wave pulses with a duration of 200 μs, triggered with the stimulation software Presentation (Neurobehavioral Systems).

Techniques: Comparison, Activity Assay

The oscillatory activity to subthreshold and suprathreshold stimulation is contralateralized. Grand average (n = 39) head plot of the SEP (blue curve) and the oscillatory activity (color-coded time-frequency plots) for subthreshold (top) and suprathreshold stimulation (bottom) in EEG session 1, after selection of central ICA components. Time is expressed relative to stimulation onset, and oscillatory activity is expressed relative to mean baseline power (baseline: 200 ms segment prestimulus).

Subthreshold stimulation increases Rolandic rhythms. Grand average time-frequency plots (contralateral to stimulation side) for subthreshold (A, EEG session 1, electrode C4, n = 39; B, EEG session 2, electrode CP4, n = 37) and suprathreshold (C, EEG session 1, electrode C4, n = 39) stimulation after selection of central ICA components. Time is expressed relative to stimulation onset, and oscillatory activity is expressed relative to baseline power (baseline: 200 ms prestimulus). The green line on the left of the time-frequency plots indicates mean baseline power. Bottom plots indicate p values derived from the permutation statistics.

Reduced connectivity of SI during subthreshold stimulation revealed by ECM. Results of a paired t test are shown for contrasting the conditions subthreshold versus rest (top), suprathreshold versus rest (middle), and subthreshold versus suprathreshold (bottom). Warm colors indicate an increase, and cold colors indicate a decrease in centrality (slice coordinates x = 143, y = 121, z = 67).

Techniques:

Reduced connectivity of SI to frontoparietal areas revealed by seed-based functional connectivity. The area described by the ECM result (Fig. 4 top, reduced eigenvector centrality during subthreshold stimulation) was used as seed. Blue areas indicate decreased correlation to the seed region, resulting from a paired t test contrasting functional connectivity maps of the subthreshold stimulation block versus rest block (fMRI session 1). Dark blue to light blue means −min to −max (slice coordinates x = 87, y = 166, z = 76).
