Functional classification of “spatial” and “behavioral” cortical sites. Spatial cortical sites have high gamma (75–150Hz) activity that discriminates spatial parameters of the task. Exemplary mean high gamma power, with standard error bars, from two spatial cortical sites discriminating (A) valid from invalid targets and (C) targets that appear contralateral from targets that appear ipsilateral to recording sites. (B) Distribution of spatial cortical sites from all subjects where red dots discriminate validity and blue dots discriminate location. Behavioral cortical sites had high gamma activity that correlated with reaction times (RTs). (D) Exemplary correlation from one behavioral cortical site. (E) The cortical surface distribution of behavioral sites from all subjects. (F) Breakdown of electrode classifications for each participant (left vertical axis) and for all participants (right vertical axis).
