Motor imagination - a model for motor performances?
International Journal of Psychophysiology, 1991The effect of training competition (TC) on central nervous activation was investigated in order to examine whether motor imagination could serve as a model for complex motor skills concerning information processing and motor control. EEG was recorded before and immediately after the TC.

Knowledge and Motor Performance
Perceptual and Motor Skills, 1992Traditionally, motor skill acquisition has implied that the performance of a given individual on a particular skill is dependent on the amount of prior practice of that skill. However, concepts such as schema theory, or kinetic formulae, or the strategic allocation of resources imply that, even when practising specific skills, performers gain knowledge

Motor Performance and Motor Learning in Lurcher Mice
Annals of the New York Academy of Sciences, 2002Abstract: In adult Lurcher mice virtually all cerebellar Purkinje cells have degenerated as a direct consequence of mutant gene action, providing a natural model for studying the effect of cerebellar cortical lesions on the generation of compensatory eye movements. Lurcher mice possess both optokinetic (OKR) and vestibular (VOR) compensatory reflexes.

Motor imagery, performance and motor rehabilitation
2018Motor imagery has been central to adzvances in sport performance and rehabilitation. Neuroscience has provided techniques for measurement which have aided our understanding, conceptualization and theorizing. Challenges remain in the appropriate measurement of motor imagery.

Comprehensive Physiology
Abstract The human sensorimotor control system has exceptional abilities to perform skillful actions. We easily switch between strenuous tasks that involve brute force, such as lifting a heavy sewing machine, and delicate movements such as threading a needle in the same machine.

Infants with Delayed Motor Performance
Pediatric Clinics of North America, 1982In judging an infant’s motor competency, one must consider achievement of motor milestones, quality of motor performance, status of infantile reflexes, tone and strength, and family history. When an infant is found to have abnormal or delayed motor performance, it is essential to use a systematic approach to evaluation that delineates whether the ...

Psychometric schizotypy and motor performance.
Journal of Abnormal Psychology, 2002Motor abnormalities have long been a focus in discussions of schizophrenia. The present study used a newly developed line drawing task to examine fine motor performance and psychometrically assessed schizotypy in a large, randomly ascertained sample of young adults (N = 120) with no history of psychosis. Poor motor performance on the line drawing task,

Performance characteristics of Brownian motors
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2005Brownian motors are nonequilibrium systems that rectify thermal fluctuations to achieve directed motion, using spatial or temporal asymmetry. We provide a tutorial introduction to this basic concept using the well-known example of a flashing ratchet, discussing the micro- to nanoscopic scale on which such motors can operate. Because of the crucial role

Transient performance of induction motors
Electrical Engineering, 1944IT has been the usual practice to solve induction-motor transient problems either on the basis of the familiar steadystate equivalent circuit or by calculations which require simplifying assumptions. These methods neglect important factors determining the performance.

Limb apraxia and motor performance
Brain and Language, 1980Abstract This study was desinged to determine if motor deficits in limb apraxia are task specific. Non-brain-damaged patients and apraxic and nonapraxic patients with left hemisphere damage performed language and limb apraxia tests and six motor tasks with the left hand. Contrary to previous data, no significant group differences occurred on a finger
