analysis allows for the examination of sequence effects as well as comparisons between trials that were not preceded by a need to adapt behavior (i.e., when a STOP follows a GO) versus trials that were preceded by a need to adapt behavior (i.e., when a STOP follows a STOP). For analysis of single units, we computed distributions of difference scores based on the raw firing rates (spikes) for each neuron. Distributions were deemed significant if they differed from either zero or one another via Wilcoxon sign-rank and rank sum/Mann–Whitney U tests, respectively.
