A major question in the field of sensory substitution concerns the nature of the perception generated by sensory substitution prostheses. Is the perception determined by the nature of the substitutive modality or is it determined by the nature of the information transmitted by the device? Is it a totally new, amodal, perception? This paper reviews the recent neuroimaging studies which have investigated the neural bases of sensory substitution. The detailed analysis of available results led us… Expand

Looking into brain activation using a sensory substitution prosthesis : seeing with sound
This PhD thesis and the scientific papers included in it were intended to provide new knowledge regarding the sensory substitution of vision and the crossmodal recruitment of the visual cortex in… Expand
Guidelines for quantitative and qualitative studies of sensory substitution experience
Information that is normally accessed through a sensory modality (substituted modality, e.g., vision) is provided by sensory substitution devices (SSDs) through an alternative modality such as… Expand
Sensory substitution as an artificially acquired synaesthesia
TLDR
This review argues that sensory substitution does indeed show properties of synaesthesia and proposes two testable predictions: firstly that, in an expert user of a sensory substitution device, the substituting modality should not be lost, and secondly that stimulation within the substitution modality, but by means other than a sensory replacement device, should still produce sensation in the normally substituted modality.

Sensory Substitution and Multimodal Mental Imagery
TLDR
It is claimed that sensory substitution assisted “vision” is neither vision nor tactile perception, because it is not perception at all; it is mental imagery: visual mental imagery triggered by tactile sensory stimulation. Expand
Mixing up the Senses: Sensory Substitution Is Not a Form of Artificially Induced Synaesthesia.
TLDR
It is found that sensory substitution does not fulfil the essential criteria that characterise synaesthesia and thus, the 'artificial synesthesia' view of sensory substitution should be rejected. Expand
The role of visual deprivation and experience on the performance of sensory substitution devices
TLDR
Establishing how experience and different etiologies of vision loss affect the performance of these devices may help to improve existing rehabilitation strategies, formulate effective selection criteria and develop prognostic measures is discussed. Expand
Individual Differences in Sensory Substitution.
TLDR
Those studies that investigated the individual differences at the behavioural, neural, and phenomenological levels when using a sensory substitution device are reviewed to highlight how taking into account individual differences has consequences for the optimization and learning of sensory substitution devices. Expand
Reading the World through the Skin and Ears: A New Perspective on Sensory Substitution
TLDR
It is shown why the analogy with reading provides a better explanation of the actual findings, that is, both of the positive results achieved and of the limitations noticed across the field of research on sensory substitution. Expand
Looking into Task-Specific Activation Using a Prosthesis Substituting Vision with Audition
A visual-to-auditory sensory substitution device initially developed for the blind is known to allow visual-like perception through sequential exploratory strategies. Here we used functional magnetic… Expand
Sensory rehabilitation in the plastic brain.
TLDR
It is stressed that the understanding of the neuroplastic changes that occur in sensory-deprived individuals may help guide the design and the implementation of such rehabilitative methods, and two promising rehabilitative strategies based on opposing theoretical principles will be considered.

The effect of visual experience on the development of functional architecture in hMT+.
TLDR
Results demonstrate that activation of h MT+ and surrounding cortex by tactile flow is not mediated by visual mental imagery and that the functional organization of hMT+ can develop to subserve tactile flow perception in the absence of any visual experience. Expand
Behavioral and neuroplastic changes in the blind: evidence for functionally relevant cross-modal interactions
TLDR
These issues have important implications for the development of visual prosthesis aimed at restoring some degree of vision in the blind, and latent pathways that participate in multisensory percepts in sighted subjects might be unmasked and may be potentiated in the event of complete loss of visual input. Expand
Cross-modal plasticity revealed by electrotactile stimulation of the tongue in the congenitally blind.
TLDR
The data reveal that cross-modal plasticity in the blind develops rapidly and that the occipital cortex is part of a functional neural network for tactile discrimination in conjunction with the posterior parietal cortex, and show that the tongue can act as a portal to convey somatosensory information to visual cortex. Expand
Blindness and brain plasticity: contribution of mental imagery? An fMRI study.
TLDR
This study shows that the primary visual area is activated in early blind subjects, and that activation persists in a mental imagery task involving no sensory input other than verbal instructions, and to the ongoing debate on brain reorganization. Expand
Functional cerebral reorganization for auditory spatial processing and auditory substitution of vision in early blind subjects.
Early blind (EB) individuals can recognize bidimensional shapes using a prosthesis substituting vision with audition (PSVA) and activate right dorsal extrastriate visual cortex during the execution… Expand
Cross-modal activation of visual cortex during depth perception using auditory substitution of vision
TLDR
Activation foci were found in visual association areas during both the target search task, which recruited the occipito-parietal cortex, and the depth perception task,Which indicates that some brain areas of the visual cortex are relatively multimodal and may be recruited for depth processing via a sense other than vision. Expand
Topographical representations of mental images in primary visual cortex
TLDR
Findings resolve a debate in the literature about whether imagery activates early visual cortex and indicate that visual mental imagery involves 'depictive' representations, not solely language-like descriptions12–14. Expand
Vertical-horizontal illusion present for sighted but not early blind humans using auditory substitution of vision
TLDR
The absence of the illusion effect in early blind subjects suggests that the sensory experience influences the nature of perception and that the visual experience plays a crucial role in the vertical-horizontal illusion, in accordance with the size-constancy scaling theory. Expand
Early ‘visual’ cortex activation correlates with superior verbal memory performance in the blind
TLDR
Using functional magnetic resonance imaging (fMRI) in ten congenitally blind human participants, robust occipital activation during a verbal-memory task (in the absence of any sensory input), as well as during verb generation and Braille reading is found. Expand
Auditory Triggered Mental Imagery of Shape Involves Visual Association Areas in Early Blind Humans
TLDR
Since shape imagery by early blind subjects does involve similar visual structures as controls at an adult age, it indicates their developmental crossmodal reorganization to allow perceptual representation in the absence of vision. Expand
