Sensory-Motor Integration: More Variability Reduces Individuality
Motor neural networks and muscles produce identifiably common outputs, such as a trot or gallop, despite varations in intrinsic properties across individuals. New work shows that sensory input can induce the requisite decrease in across-individual variability even as it increases within-individual variability.
متن کاملSensory Feedback Reduces Individuality by Increasing Variability within Subjects
Behavioral variability is ubiquitous [1-6], yet variability is more than just noise. Indeed, humans exploit their individual motor variability to improve tracing and reaching tasks [7]. What controls motor variability? Increasing the variability of sensory input, or applying force perturbations during a task, increases task variability [8, 9]. Sensory feedback may also increase task-irrelevant ...
متن کاملMotor learning reduces eye movement variability through reweighting of sensory inputs.
Motor learning can improve both the accuracy and precision of motor performance. We analyzed changes in the average trajectory and the variability of smooth eye movements during motor learning in rhesus monkeys. Training with a compound visual-vestibular stimulus could reduce the variability of the eye movement responses without altering the average responses. This improvement of eye movement p...
متن کاملSensory-Motor Integration in the Medial Medulla
The rostromedial medulla, including the nucleus gigantocellularis (NGC) and magnocellularis (NMC), plays a role as a relay nucleus for both the sensory and motor systems. The NGC/NMC is important in the modulation of somatic and visceral activities. Electrophysiological and pharmacological studies have shown that the NGC/NMC is involved in nociception, locomotion, regulation of basal muscle ton...
متن کاملThe Effect of Sensory Integration on the Attention and Motor Skills of Students With Down Syndrome
Objectives: Sensory integration training plays a crucial role on the attention span and motor skills of students with Down syndrome. The present research aimed to investigate the effect of sensory integration training on the attention span and motor skills of students with Down syndrome. Methods: This was a quasi-experimental research with a pretest, posttest design and control group. Partici...
