Reducing attention bias toward negative emotional stimuli with transcranial random noise stimulation: a randomized, double-blind, sham-controlled, crossover study.

Positive associations were observed for both tRNS and tDCS; however, these did not reach statistical significance in the within-subject label-flip permutation test (tRNS: r = 0.844, permuted p = 0.104; tDCS: r = 0.557, permuted p = 0.772).
