Retinotopically Specific Reorganization of Visual Cortex for Tactile Pattern Recognition
Although previous studies have shown that Braille reading and other tactile discrimination tasks activate the visual cortex of blind and sighted people, it is not known whether this kind of crossmodal reorganization is influenced by retinotopic organization. We have addressed this question by studying "S," a visually impaired adult with the rare ability to read print visually and Braille by tou...
متن کاملLocalizing Non-Retinotopically Moving Objects
How does the brain determine the position of moving objects? It turns out to be rather complex to answer this question when we realize that the brain has to solve the motion correspondence problem in two kinds of reference frames: Retinotopic and non-retinotopic ones. We show that visual objects are mislocalized along a non-retinotopic motion direction. Observers viewed two successive movie fra...
متن کاملAnticipatory Biasing of Visuospatial Attention Indexed by Retinotopically Specific a-Band Electroencephalography Increases over Occipital Cortex
a-Band (8–14 Hz) oscillatory EEG activity was examined with high-density scalp electrical recording during the cue–stimulus interval of an endogenous spatial cueing paradigm. In different blocks, cued spatial locations (left or right) were in either the upper or lower visual field, and attended stimuli were either oriented Ts or moving dots. Distractor stimuli were equally likely in the uncued ...
متن کاملFlexible Scale Use 1 Running head: FLEXIBLE SCALE USE IN SCENE PERCEPTION Top-down Attentional Modulation of Spatial Frequency Processing in Scene Perception
Recent evidence suggests that spatial frequency (SF) processing of simple and complex visual patterns is flexible. The use of spatial scale in scene perception seems to be influenced by people’s expectations. However as yet there is no direct evidence for top-down attentional effects on flexible scale use in scene perception. In two experiments we provide such evidence. We presented participant...
متن کاملAnticipatory biasing of visuospatial attention indexed by retinotopically specific alpha-band electroencephalography increases over occipital cortex.
Alpha-band (8-14 Hz) oscillatory EEG activity was examined with high-density scalp electrical recording during the cue-stimulus interval of an endogenous spatial cueing paradigm. In different blocks, cued spatial locations (left or right) were in either the upper or lower visual field, and attended stimuli were either oriented Ts or moving dots. Distractor stimuli were equally likely in the unc...
