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.

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

Visual and Motor Mental Imagery After Brain Damage
2012This chapter presents evidence from brain-damaged patients relevant to the debate concerning the neural underpinnings of visual and motor mental imagery capacities. For visual mental imagery, the domains of object shape and color, orthographic material, and spatial imagery (imaginal neglect) are examined.

Visual motor imagery predominance in professional Spanish dancers.
Somatosensory & motor research, 2020Purpose: The main objectives of the study were to analyse the predominant motor imagery modality used by professional Spanish dancers and to compare Spanish dancers' ability to perform mental motor imagery with that of non-dancers, and to analyse differences between male and female dancers.

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 ...

Task-dependent engagements of the primary visual cortex during kinesthetic and visual motor imagery
Neuroscience Letters, 2017Motor imagery can be divided into kinesthetic and visual aspects. In the present study, we investigated excitability in the corticospinal tract and primary visual cortex (V1) during kinesthetic and visual motor imagery. To accomplish this, we measured motor evoked potentials (MEPs) and probability of phosphene occurrence during the two types of motor ...

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), 2019There 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,

Evidence for the online operation of imagery: Visual imagery modulates motor production in drawing
Behavioral and Brain Sciences, 2004One 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 ...

Laterality in Parkinson's disease may predict motor and visual imagery abilities.
Functional neurology, 2018Experimental evidence suggests that motor imagery (MI) engages the same neural substrates supporting actual motor activities and is likely impaired when such substrates are damaged, as in Parkinson's disease (PD). MI intuitively relies on visual imagery (VI), because mental simulations of physical movements depend on the visual retrieval of these ...
