A neural mechanism for coordinate transformation predicts pre-saccadic remapping

Tactile remapping: from coordinate transformation to integration in sensorimotor processing.

Tactile localization entails the transformation of the initial skin-based location into an external reference frame that accounts for body posture and subsequent flexible integration of these two reference frames. The mechanisms underlying this tactile remapping are not well understood. Notably, there is a gap between the principles uncovered by psychophysical research and the mechanistic expla...

a new method for coordinate transformation between conformal map projections

geospatial information system (gis) has emerged as a very powerful tool for capturing, storing, analyzing, managing, and presenting data that is linked to location. the location information, which is usually obtained from existing maps or the global positioning systems (gps), refers to different coordinate and map projection systems. therefore, unification of the coordinate and mapping systems ...

Parietal lobe lesions disrupt saccadic remapping of inhibitory location tagging.

Maintaining a coherent percept of the visual scene while eye position continuously changes requires that saccades be accompanied by remapping of the visual environment. We studied saccadic remapping in patients with unilateral lesions in the intraparietal sulcus and healthy controls, using inhibition of return (IOR)-an inhibitory tag that enables efficient visual search. In healthy controls, IO...

Temporal dynamics of remapping captured by peri-saccadic continuous motion.

Different attention and saccade control areas contribute to space constancy by remapping target activity onto their expected post-saccadic locations. To visualize this dynamic remapping, we used a technique developed by Honda (2006) where a probe moved vertically while participants made a saccade across the motion path. Observers do not report any large excursions of the trace at the time of th...
