Activity in the posterior parietal cortex mediates visual dominance over kinesthesia.
When both visual and kinesthetic information of a limb are available, vision is usually the dominant source of information used to perceive the spatial location. In this study, we conducted behavioral and functional magnetic resonance imaging (fMRI) experiments to examine the brain mechanisms underlying the visual dominance over kinesthesia in perceiving the position of a hand. We used tendon v...
متن کاملMaintenance of Visual Stability in the Human Posterior Parietal Cortex
Visual stability refers to our stable visuospatial perceptions despite the unstable visual input caused by saccades. Functional neuroimaging results, studies on patients with posterior parietal cortex (PPC) lesions, and single-unit recordings in the lateral intraparietal sulcus of primates indirectly suggest that the PPC might be a potential locus of visual stability through its involvement wit...
متن کاملHuman posterior parietal cortex mediates hand-specific planning
The processes underlying action planning are fundamental to adaptive behavior and can be influenced by recent motor experience. Here, we used a novel fMRI Repetition Suppression (RS) design to test the hypotheses that action planning unfolds more efficiently for successive actions made with the same hand. More efficient processing was predicted to correspond with both faster response times (RTs...
متن کاملVisual and eye movement functions of the posterior parietal cortex.
Lesions of the posterior parietal area in humans produce interesting spatial-perceptual and spatial-behavioral deficits. Among the more important deficits observed are loss of spatial memories, problems representing spatial relations in models or drawings, disturbances in the spatial distribution of attention, and the inability to localize visual targets. Posterior parietal lesions in nonhuman ...
متن کاملIntention-related activity in the posterior parietal cortex: a review
Over the last few years it is becoming increasingly apparent that an important role of the posterior parietal cortex is to process sensory information for the purpose of planning actions. We review studies showing that a large component of neural activity in area LIP is related to planning saccades and activity in a nearby parietal reach region (PRR) to reaches. This intention related activity ...
