The effects of visual impairment on motor imagery in children and adolescents.

Research in Developmental Disabilities, 2021
BACKGROUND While the development of motor imagery (MI) has been extensively studied in sighted children, it is not clear how children with different severities of visual impairment (VI) represent motor actions by using the motor representations ...

Relationship Between Kinesthetic/Visual Motor Imagery Difficulty and Event-Related Desynchronization/Synchronization

Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2018
Motor imagery (MI) is divided into two types: kinesthetic (KMI) and visual (VMI). To estimate the MI that an examinee performs, event-related desynchronization (ERD) or event-related synchronization (ERS) is used to characterize KMI or VMI via ...

Postural Control During Visual and Kinesthetic Motor Imagery

Applied Psychophysiology and Biofeedback, 2011
Despite the accumulating evidence supporting an interaction between cognitive functions and postural control, little is known about the selective impact of the mental representation of an action, i.e., motor imagery (MI) on postural control. As postural oscillations are reduced during a cognitive task of backward silent counting, a greater stability is

Visually guided motor imagery activates sensorimotor areas in humans

Neuroscience Letters, 1999
Stimulus-related changes in ongoing electroencephalography (EEG) over sensorimotor areas were investigated during a visually cued motor imagery task. Four subjects were instructed to imagine one-sided hand movements in response to visual cue stimuli. The EEG was recorded from central areas using 27 electrodes set at distances of 2.5 cm.

Exploring motor and visual imagery in Amyotrophic Lateral Sclerosis

Experimental Brain Research, 2013
Amyotrophic Lateral Sclerosis (ALS) is a motor neuron disease characterized by the progressive atrophy of both the first and the second motor neurons. Although the cognitive profile of ALS patients has already been defined by the occurrence of language dysfunctions and frontal deficit symptoms, it is less clear whether the degeneration of upper and ...

Testing the Distinctiveness of Visual Imagery and Motor Imagery in a Reach Paradigm

International Journal of Neuroscience, 2009
We examined the distinctiveness of motor imagery (MI) and visual imagery (VI) in the context of perceived reachability. The aim was to explore the notion that the two visual modes have distinctive processing properties tied to the two-visual-system hypothesis.

Controllability of Motor Imagery and Transformation of Visual Imagery

Perceptual and Motor Skills, 1994
This study examined the relation between control of motor imagery and generation and transformation of visual imagery by testing 54 subjects. We used two measures of the Controllability of Motor Imagery test to evaluate the ability to control motor imagery. One was a recognition test on which the subject imagines as if one sees another's movement, and

Motor and Visual Imagery in Sports

2012
Mental practice routines play an important role in many different sports, not only for the acquisition of motor skills but also for preparation prior to competitive events and rehabilitation after sport injuries. Imagery techniques in sport are used for different purposes, as outlined by the Model of Imagery Use in Sports [Martin et al.

The Effects of Visual Distractors on Cognitive Load in a Motor Imagery Brain-Computer Interface.

Behavioural Brain Research, 2020
A brain-computer interface (BCI) is a system that translates neural activity into a practical output. Its functionality, therefore, depends not only on the computer itself, but also on the cognitive system of the user.

On the relation between motor imagery and visual imagery

Behavioral and Brain Sciences, 1994
Jeannerod's target article describes support, through empirical and neurological findings, for the intriguing idea of motor imagery, a form of representation hypothesized to have levels of functional equivalence with motor preparation, while being consciously accessible.
