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.

Imagery of motor actions: Differential effects of kinesthetic and visual–motor mode of imagery in single-trial EEG

Cognitive Brain Research, 2005
Single-trial motor imagery classification is an integral part of a number of brain-computer interface (BCI) systems. The possible significance of the kind of imagery, involving rather kinesthetic or visual representations of actions, was addressed using the following experimental conditions: kinesthetic motor imagery (MIK), visual-motor imagery (MIV ...

Visual Imagery and Motor Phenomena in Acute Schizophrenia

British Journal of Psychiatry, 1967
This paper deals briefly with a few clinical observations made in the course of studies of changes in subjective experience reported by young patients in the early stages of schizophrenia. These studies aimed at delineating the early schizophrenic clinical picture in as specific a manner as possible with a view to later experimental validation, and the

Adolescent development of motor imagery in a visually guided pointing task

Consciousness and Cognition, 2007
The development of action representation during adolescence was investigated using a visually guided pointing motor task (VGPT) to test motor imagery. Forty adolescents (24 males; mean age 13.1 years) and 33 adults (15 males; mean age 27.5 years) were instructed to both execute and imagine hand movements from a starting point to a target of varying ...

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.

Multisensory approach in Mental Imagery: ALE meta-analyses comparing Motor, Visual and Auditory Imagery

Neuroscience and Biobehavioral Reviews
Abstract Mental Imagery is a topic of longstanding and widespread scientific interest. Individual studies have typically focused on a single modality (e.g. Motor, Visual, Auditory) of Mental Imagery. Relatively little work has considered directly comparing and contrasting the brain networks associated with these different modalities of ...

Motor imagery in blind subjects: The influence of the previous visual experience

Neuroscience Letters, 2006
Mental simulation of movements has been widely used to infer about representational aspects of action. On a daily basis, motor planning and execution depends crucially both upon vision and kinesthesia. What if the former is lost? In this study we investigate the physiological changes induced during a mental simulation task in subjects with early and ...

Motor imagery beyond the motor repertoire: Activity in the primary visual cortex during kinesthetic motor imagery of difficult whole body movements

Neuroscience, 2016
To elucidate the neural substrate associated with capabilities for kinesthetic motor imagery of difficult whole-body movements, we measured brain activity during a trial involving both kinesthetic motor imagery and action observation as well as during a trial with action observation alone.

Evidence for the online operation of imagery: Visual imagery modulates motor production in drawing

Behavioral and Brain Sciences, 2004
One property of the emulator framework presented by Grush is that imagery operates off-line. Contrary to this viewpoint, we present evidence showing that mental rotation of a simple figure modulates low-level features of drawing articulation. This effect is dependent upon the type of rotation, suggesting a more integrative online role for imagery than ...

Enhancement of motor cortex EEG during motor imagery: a visual feedback training study

2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA), 2019
There are some limitations for the motor imagery Electroencephalogram (EEG) including low-spatial resolution, non-stationary and susceptible to noise interference. This study aims to enhance the EEG features via an visual feedback training process by improving the visual feedback training paradigm design, EEG signal acquisition and EEG signal analysis,
