Abstract Implicit motor sequence learning (IMSL) enables us to perform multiple single movements in a specific sequential order and is involved many of our daily activities (e.g., reaching, walking). Acquisition IMSL has been shown be significantly impaired Parkinson’s disease (PD). Research healthy individuals shows the potential for transcranial direct current stimulation (tDCS), non-invasive...

INTRODUCTION Many forms of movements were combined with several motor skills, example for catching and passing skills of baseball infields. From the viewpoint of dynamic system theory, these motor skills might be affected by each motor (Newell & Corcos, 1993). For handball players, the skill of moving body and passing the ball were very important. One of the abilities in passing ball was relate...

Cerebellar contributions to motor learning are well-documented. For example, under some conditions, patients with cerebellar damage are impaired at visuomotor adaptation and at acquiring new action sequences. Moreover, cerebellar activation has been observed in functional MRI (fMRI) investigations of various motor learning tasks. The early phases of motor learning are cognitively demanding, rel...

objectives: the aim of this study was to determine the effect of perceptual-motor training on motor skills of normal preschool children (aged 4-6 years) in esfahan city. methods: this was a quasi-experimental study with intervention and control groups. each group included 30 normal preschool children aged 4 to 6 years. they were selected randomly children of intervention group one empowering ch...

The aim of this paper is to present a new model for the linear induction motor (LIM), which is based on its equivalence with the asymmetrical rotary induction motor. The model uses the theory of positive, negative and zero sequence of symmetrical and asymmetrical components. Experimental and simulation procedures with a LIM prototype allowed the theoretical and experimental validation for this ...

The aim of the present study was to investigate the influence of focal cerebellar lesions on procedural learning. Eight patients with cerebellar lesions and six control subjects were tested in a serial reaction-time task. A four-choice reaction-time task was employed in which the stimuli followed (or not) a sequence repeated 10 times, with the subjects aware (or not) of the item sequence. Learn...

The medial frontal cortex has been thought to be crucially involved in temporal structuring of behavior in monkeys and humans. We examined neuronal activity in the supplementary and presupplementary motor areas of monkeys to investigate how the nervous system deals with the coding of 16 motor sequences resulting from multiple actions involving bilateral use of the arms. We first found in both a...

How do people remember and produce complex sequences like music or speech? Music provides an example of excellent sequence memory under fast performance conditions; novices as well as skilled musicians can perform memorized music rapidly, without making mistakes. In addition, musical pitches repeat often within a melodic sequence in different orders, yet people do not confuse the sequential ord...
