Accuracy at smaller separations. As both groups completed the SND condition at a relatively high level of accuracy, a separation challenge was conducted where one block was given of each smaller separation (sessions cycled through separations, punctuated with sessions of all separations). While smaller separations were more difficult, there was no difference between sham and lesion. Separation shows the number of horizontal locations in between the active choice locations (0 being adjacent). Data presented as block means ± 1SEM.
