  • Percent signal change (vs passive) within left and right retinotopically mapped IPS0-4 during LTM-guided and stimulus-guided attention to the contralateral and ipsilateral visual field. F-statistics and p-values refer to the significance of the three-way (Hemisphere × Condition × Visual Field) interaction.
