Timing independent spatial motor sequence learning is preserved in left hemisphere stroke
Publication date: Available online 28 September 2017 Source:Neuropsychologia Author(s): Anna Dovern, Eva Niessen, Jana M. Ant, Jochen Saliger, Hans Karbe, Gereon R. Fink, Iring Koch, Peter H. Weiss During neurorehabilitation, the re-learning of motor sequences is crucial for patients with motor deficits, enabling them to master again complex movements. A recent study showed that patients with left hemisphere (LH) stroke exhibited preserved motor sequence learning (as assessed by the serial reaction time (SRT) task) when the timing of the stimuli was comparable in the training and later test phase. However, patients showed...

Does it fit? – Impaired affordance perception after stroke
Publication date: 8 January 2018 Source:Neuropsychologia, Volume 108 Author(s): Jennifer Randerath, Lisa Finkel, Cheryl Shigaki, Joe Burris, Ashish Nanda, Peter Hwang, Scott H. Frey Affordance perception comprises the evaluation of whether our given bodily capabilities and properties of the environment allow particular actions. Typical impairments after left brain damage in motor cognition as well as after right brain damage in visuo-spatial abilities may affect the evaluation of whether interactions with objects are possible. Further it is unclear whether deficient motor function is accounted for when deciding upon actio...

Clinical impact of gait training enhanced with visual kinematic biofeedback: Patients with Parkinson’s disease and Patients stable post stroke☆
Publication date: Available online 22 April 2015 Source:Neuropsychologia Author(s): Nancy Byl , Wenlong Zhang , Sophia Coo , Masayoshi Tomizuka As the world’s population ages, falls, physical inactivity, decreased attention and impairments in balance and gait arise as a consequence of decreased sensation, weakness, trauma and degenerative disease. Progressive balance and gait training can facilitate postural righting, safe ambulation and community participation. This small randomized clinical trial evaluated if visual and kinematic feedback provided during supervised gait training would interfere or enhance mobility, e...

Re-learning and remembering in the lesioned brain
We report on two studies that examine whether or not these principles also apply in language re-learning and retention for individuals with acquired deficits in written language production. Study 1 compared distributed vs. clustered training schedules, while Study 2 examined—for the first time in the context of re-learning—the relationship between the spacing of training trials and retention period. This investigation revealed that, despite significant cognitive deficits and brain lesions, remarkably similar principles govern re-learning and retention in the lesioned brain as have been found to apply in neurologically ...

Impaired binocular fusion as a cause of “Flat Vision” after right parietal brain damage – A case study
Publication date: Available online 22 January 2015 Source:Neuropsychologia Author(s): Anna-Katharina Schaadt , Stephan A. Brandt , Antje Kraft , Georg Kerkhoff The complete loss of binocular depth perception (“Flat Vision”) was first thoroughly described by Holmes and Horrax (1919), and has been occasionally reported thereafter in patients with bilateral posterior-parietal lesions. Though partial spontaneous recovery occurred in some cases, the precise cause(s) of this condition remained obscure for almost a century. Here, we describe a unique patient (EH) with a large right-sided occipito-parietal hemorrhage showing...
