An increase of local cerebral blood flow or metabolic demands has been detected in those regions. Functional integration of the neuronal circuits that subserve the task performance, based upon the identification of the oscillations and their distributed cerebral sources, has not been accomplished previously. The event\u2010related tonic oscillations within a period of 2,000 msec after the stimulus onset and the probable neural substrate were evaluated in healthy volunteers by variable\u2010resolution brain electrical tomography (VARETA). The WCST induced a significant increase of \u03b4, \u03b8, \u03b2\u20102, and \u03b3 oscillations, but decrease of \u03b1. Areas such as the frontal subregions, temporal, cingulate, parahippocampal, parietal, occipitotemporal cortex, and occipital poles showed modified activity during the task, with EEG spectral band selectivity as well as some overlapping among them. Frontal and temporal regions generated the \u03b4\/\u03b8 oscillations. Additionally, the occipitotemporal and parietal regions were the source of the \u03b4 activity, lacking \u03b8 activation. The parietal region also showed tonic \u03b1, \u03b2\u20102 and \u03b3 changes. These data imply that different processes have been simultaneously mediated during task performance. Relationships among the individual bands, the neural substrata and the specific cognitive process that support the task were established. The selectively distributed \u03b4, \u03b8, \u03b1, \u03b2\u20102 and \u03b3 oscillations reflect communication networks through variable populations of neurons, with functional relations to the working memory functions and the information processing that subserve the WCST performance.
