Effects of Delayed Visual Feedback on Grooved Pegboard Test Performance
Using four experiments, this study investigates what amount of delay brings about maximal impairment under delayed visual feedback and whether a critical interval, such as that in audition, also exists in vision. The first experiment measured the Grooved Pegboard test performance as a function of visual feedback delays from 120 to 2120 ms in 16 steps. Performance sharply decreased until about 4...
متن کاملRole of microRNA as a biomarker in Alzheimer’s disease
Introduction: MicroRNAs are small, non-coding, and protected RNA molecules that regulate gene expression after transcription by mRNA degradation or inhibition of protein synthesis. The function of these molecules is critical to many cellular processes, including growth, development, differentiation, homeostasis, apoptosis, aging, stress resistance. In addition, some diseases including cancer, a...
متن کاملImaging muscle as a potential biomarker of denervation in motor neuron disease
OBJECTIVE To assess clinical, electrophysiological and whole-body muscle MRI measurements of progression in patients with motor neuron disease (MND), as tools for future clinical trials, and to probe pathophysiological mechanisms in vivo. METHODS A prospective, longitudinal, observational, clinicoelectrophysiological and radiological cohort study was performed. Twenty-nine patients with MND a...
متن کاملThe Influence of Parkinson's Disease Motor Symptom Asymmetry on Hand Performance: An Examination of the Grooved Pegboard Task.
This study examined the influence of motor symptom asymmetry in Parkinson's disease (PD) on Grooved Pegboard (GP) performance in right-handed participants. The Unified Parkinson's Disease Rating Scale was used to assess motor symptoms and separate participants with PD into two groups (right-arm affected, left-arm affected) for comparison with a group of healthy older adults. Participants comple...
متن کاملthe significance of conjunction as a cohesive device in teaching writing
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
