Controllability of Motor Imagery and Transformation of Visual Imagery
Perceptual and Motor Skills, 1994This 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.

Motor and Visual Imagery in Sports
2012Mental 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.

Visual Training Improves Motor Imagery Ability for Rehabilitation
2021 International Conference on Artificial Intelligence and Mechatronics Systems (AIMS), 2021Motor imagery (MI) is the most favorable brain action exploited in motor deficit rehabilitation. The hemodynamic response (HR) signal is usually weak, which can be enhanced with specific methods. In this research, the improvement in the HR was examined while the participants performed the MI task of right-hand movement.

Postural Control During Visual and Kinesthetic Motor Imagery
Applied Psychophysiology and Biofeedback, 2011Despite 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

Exploring motor and visual imagery in Amyotrophic Lateral Sclerosis
Experimental Brain Research, 2013Amyotrophic 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 ...

On the relation between motor imagery and visual imagery
Behavioral and Brain Sciences, 1994Jeannerod'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.

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, 1967This 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, 2007The 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, 1999Stimulus-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.
