Attention- and action-related oscillatory dynamics in a visuomotor network.

ABSTRACT: A network model of a "selection-for-action" system was proposed with the primary idea that the functions of stimulus and response selection are carried out within a visuomotor oscillatory network. To examine the network's dynamics under different sensorimotor demands, an electroencephalographic experiment was performed, contrasting visual detection and discrimination variants of a Posner cueing task. In the former, the required response can be prepared before target onset, whereas in the latter-only after target onset. Using the generalized eigenvalue decomposition method for EEG source isolation, we identified four network subcomponents: lateral motor, lateral visual, midfrontal, and midparietal sources. The local and inter-source activity relevant for spatial attention (visual and midpar
