Prism adaptation in Parkinson's disease. [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1988 Prism adaptation is impaired by lesions in the basal ganglia in non-human primates, suggesting that this area is involved in this form of visuomotor learning. We investigated the ability of patients with Parkinson's disease to prism adapt. Patients and controls wore prisms which deflected vision laterally by 11 degrees.

Using remarkability to define coastal flooding thresholds. [PDF]
, 2020 Coastal flooding is increasingly common in many areas. However, the degree of inundation and associated disruption depend on local topography as well as the distribution of people, infrastructure and economic activity along the coast.

The effects of prior exposure to prism lenses on de novo motor skill learning.
PLoS ONE, 2023 Motor learning involves plasticity in a network of brain areas across the cortex and cerebellum. Such traces of learning have the potential to affect subsequent learning of other tasks. In some cases, prior learning can interfere with subsequent learning,

Improvement of Mental Imagery after Prism Exposure in Neglect: A Case Study
Behavioural Neurology, 1999 Previous work has shown that various symptoms of unilateral neglect, including the pathological shift of the subjective midline to the right, may be improved by a short adaptation period to a prismatic shift of the visual field to the right.

The Effect of a Complex Intervention Program for Unilateral Neglect in Patients with Acute-Phase Stroke: A Randomized Controlled Trial [PDF]
Osong Public Health and Research Perspectives, 2019 Objectives The purpose of this study was to examine the combined effects of Prism Adaptation (PA) plus functional electrical stimulation (FES) on stroke patients with unilateral neglect, and suggest a new intervention method for acute-phase stroke ...

Adaptive electrowetting lens-prism element
Optics Express, 2015 An adaptive electrowetting-based element with focusing and steering capability has been demonstrated in a monolithic design. Curvature and tip-tilt variation have been demonstrated using low voltages. A steering range of up to 4.3° and lens tuning of 18 diopters have been measured at 30 V DC and 21 V DC, respectively.

Three timescales in prism adaptation
Journal of Neurophysiology, 2015 It has been proposed that motor adaptation depends on at least two learning systems, one that learns fast but with poor retention and another that learns slowly but with better retention (Smith MA, Ghazizadeh A, Shadmehr R. PLoS Biol 4: e179, 2006). This two-state model has been shown to account for a range of behavior in the force field adaptation ...

Induced prismatic effects due to poorly fitting spectacle frames
African Vision and Eye Health, 2011 To provide patients with the best vision possible practitioners undertake comprehensive visual examinations and optical dispensing procedures. Ensuring proper frame alignment is an important part of the spectacle dispensing process.

Influence of Visual Prism Adaptation on Auditory Space Representation
i-Perception, 2017 Prisms shifting the visual input sideways produce a mismatch between the visual versus felt position of one’s hand. Prism adaptation eliminates this mismatch, realigning hand proprioception with visual input. Whether this realignment concerns exclusively
