objective: the cerebellum is a key structure involved in coordinated motor planning, cognition, learning and memory functions. this study presents a permanent model of a toxin produced cerebellar lesion characterized according to contemporary motor and cognitive abnormalities. materials and methods: in this experimental study, slow administration of quinolinic acid (qa, 5 μl of 200 μmol, 1 μl/m...

Objectives: The visual-motor skill is one of the major factors in the learning process. Visual-spatial and visual analysis skills are components of the visual motor skill. Any deficiency in Visual-Motor skills and their components often causes problem in writing and learning processes in children. The aim of this study was to investigate the effect of occupational therapy (O.T.) intervention on...

Abstract Background and Aim: The aim of this study was to investigate the mediating role of executive functions in the relationship between fine motor skills and reading skills in students with reading disorders. Method: This research was descriptive-correlation and structural equation modeling. The research population of the study included all students with reading disorders who referred t...

  Background: Learning disability is one of the most noticed subjects for behavioral specialists. Most of the learning difficulties are caused by senso-motor development and neurological organization. The main purpose of the present research is to examine the role of delayed perceptual-motor development and brain damage in origination of expressive writing disorder (EWD).   Methods: The studi...

Introduction: Aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. Aluminum ions in the brain cause serious problems such as Alzheimer, Parkinson and other degenerative diseases. On the other hand, Zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates wi...

UNLABELLED The generalization of learning offers a unique window for investigating the nature of motor learning. Error-based motor learning reportedly cannot generalize to distant directions because the aftereffects are direction specific. This direction specificity is often regarded as evidence that motor adaptation is model-based learning, and is constrained by neuronal tuning characteristics...

motor imagery is the ability to imagine performing a movement without any action. the time a movement is mentally rehearsed highly correlates with the actual time of motor action. in this study, the effect of voluntary changes in imagery speed on the duration of the actual performance and learning a complex unfamiliar skill, and also the difference between the effects of real-time and fast imag...
