Prism adaptation theory in unilateral neglect: motor and perceptual components
Striemer and Danckert (2010a) suggest that prism adaptation (PA) has beneficial effects primarily on spatial attention and the motor components of neglect, and that the direct effects on visual neglect are insignificant. The main support for their influential hypothesis (e.g., Saj et al., 2013) comes from their own study (Striemer and Danckert, 2010b), but Saevarsson and Kristjánsson (2013) cri...
متن کاملSpatial Compression Impairs Prism Adaptation in Healthy Individuals
Neglect patients typically present with gross inattention to one side of space following damage to the contralateral hemisphere. While prism-adaptation (PA) is effective in ameliorating some neglect behaviors, the mechanisms involved and their relationship to neglect remain unclear. Recent studies have shown that conscious strategic control (SC) processes in PA may be impaired in neglect patien...
متن کاملEffects of prism adaptation on motor-intentional spatial bias in neglect.
Prism adaptation may alleviate some symptoms of spatial neglect. However, the mechanism through which this technique works is still unclear. This study investigated whether prism adaptation differentially affects dysfunction in perceptual-attentional 'where' bias versus motor-intentional 'aiming' bias. Five neglect patients performed a line bisection task in which lines were viewed under both n...
متن کاملBeyond the Sensorimotor Plasticity: Cognitive Expansion of Prism Adaptation in Healthy Individuals
Sensorimotor plasticity allows us to maintain an efficient motor behavior in reaction to environmental changes. One of the classical models for the study of sensorimotor plasticity is prism adaptation. It consists of pointing to visual targets while wearing prismatic lenses that shift the visual field laterally. The conditions of the development of the plasticity and the sensorimotor after-effe...
متن کاملPrism adaptation alters spatial remapping in healthy individuals: evidence from double-step saccades.
The visual system is able to represent and integrate large amounts of information as we move our gaze across a scene. This process, called spatial remapping, enables the construction of a stable representation of our visual environment despite constantly changing retinal images. Converging evidence implicates the parietal lobes in this process, with the right hemisphere having a dominant role. ...
