Overall signal change modulated by spatial attention and attended hemifield, multivoxel pattern classification predicting the direction of attention. (A) Percent signal increase in attend blocks compared with baseline in selected ROIs. The activation from frontal and temporal ROIs is shown for illustration, not statistical purposes, since such analysis would be circular. (B) Contralateral effect = attend contralateral hemifield − attend ipsilateral hemifield). (C) Multivoxel pattern classification accuracy in predicting left versus right attend blocks in the same ROIs.
