(A) Component contributions of factors identified by factor analysis of the DC/StimDur data. Bars with a positive (filled) or negative (open) loading greater than 0.4 indicate primary components of that factor. (B) Two-way ANOVA of factor scores separated by LDC (blue) and HDC (red) with short (open bar) and long (filled bar) stimulation duration for each factor (means ± s.d.). * indicates significant main effect of DC, # indicates a main effect of StimDur and ^ indicates a significant interaction of DC × StimDur.
