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.

Motor imagery in blind subjects: The influence of the previous visual experience
Neuroscience Letters, 2006Mental 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 ...

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 ...

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,

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 ...

Use of implicit motor imagery for visual shape discrimination as revealed by PET
Nature, 1995Positron emission tomography (PET) can be used to map brain regions that are active when a visual object (for example, a hand) is discriminated from its mirror form. Chronometric studies suggest that viewers 'solve' this visual shape task by mentally modelling it as a reaching task, implicitly moving their left hand into the orientation of any left ...

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.

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 ...

Despite its use in numerous domains, motor imagery (MI) can be less effective than physical practice for learning. One reason for this gap may be a lack of feedback during MI. The current research aimed to determine whether visual feedback in virtual reality (VR) impacted learning of a complex novel skill through MI.
