Adaptation to the prismatic effects of refractive lenses
Adaptation to the simple visual displacement of prisms was compared to that for refractive lenses, which have a varied prismatic effect. Subjects were made myopic using contact lenses, then corrected using spectacle lenses. The effect on the perceived direction of a randomly located target was assessed from pointing behavior. Prism adaptation showed a negative directional aftereffect but lacked...
متن کاملLimited Plasticity of Prismatic Visuomotor Adaptation
Movements toward an object displaced optically through prisms adapt quickly, a striking example for the plasticity of neuronal visuomotor programs. We investigated the degree and time course of this system's plasticity. Participants performed goal-directed throwing or pointing movements with terminal feedback before, during, and after wearing prism goggles shifting the visual world laterally ei...
متن کاملPrismatic adaptation under scotopic and photopic conditions.
Prismatic rearrangement experiments were performed under scotopic and photopic conditions by suitably darkor light-adapted .S's. Adaptation to prismatic displacement was highly significant when exposure and test procedures were carried out under scotopic as well as photopic conditions. Transfer experiments suggest that scotopically induced adaptation can be demonstrated under both scotopic and ...
متن کاملPrismatic adaptation changes visuospatial representation in the inferior parietal lobule.
Prismatic adaptation has been shown to induce a realignment of visuoproprioceptive representations and to involve parietocerebellar networks. We have investigated in humans how far other types of functions known to involve the parietal cortex are influenced by a brief exposure to prismatic adaptation. Normal subjects underwent an fMRI evaluation before and after a brief session of prismatic ada...
متن کاملOctahedral to trigonal prismatic distortion driven by subjacent orbital π antibonding interactions and modulated by ligand redox noninnocence.
Ru(ONO)2 and Os(ONO)2 distort from octahedral towards trigonal prismatic geometry in order to relieve π antibonding due to donation from the second-highest ligand orbital to the metal. Increasing oxidation of the ONO ligand suppresses distortion by increasing σ* interactions in the trigonal prism.
