“…abnormalities of function were associated, for the majority of the areas, with abnormalities of structure within the visual and auditory cortices. A recent single-case study showed extensively increased structural connections between the auditory and secondary somatosensory cortex in the lesioned hemisphere of a patient with acquired auditory-tactile synesthesia [Ro et al, 2012].…”

In PN, RS FC modifications extend beyond the sensorimotor network and involve other sensory and cognitive networks. The correlations between RS FC patterns and disease duration in patients as well as with clinical impairment in patients with APN suggest that modifications of FC might reflect an adaptive mechanism, which takes time to occur and helps to limit the clinical consequences of peripheral damage.

“…However, some supporting human evidence is found in prior reports. Ro, Ellmore, and Beauchamp (2013) used DTI and showed direct connectivity in humans between primary auditory cortex and primary somatosensory cortex. Eickhoff et al (2010) showed both structural and functional connections between primary motor cortex and operculum parietal (OP) 4, and functionally linked OP 4 to more basic sensorimotor as opposed to somatosensory processing.…”

What adaptations allow humans to produce and perceive speech so effortlessly? We show that speech is supported by a largely undocumented core of structural and functional connectivity between the central sulcus (CS or primary motor and somatosensory cortex) and the transverse temporal gyrus (TTG or primary auditory cortex). Anatomically, we show that CS and TTG cortical thickness covary across individuals and that they are connected by white matter tracts. Neuroimaging network analyses confirm the functional relevance and specificity of these structural relationships. Specifically, the CS and TTG are functionally connected at rest, during natural audiovisual speech perception, and are coactive over a large variety of linguistic stimuli and tasks. Importantly, across structural and functional analyses, connectivity of regions immediately adjacent to the TTG are with premotor and prefrontal regions rather than the CS. Finally, we show that this structural/functional CS-TTG relationship is mediated by a constellation of genes associated with vocal learning and disorders of efference copy. We propose that this core circuit constitutes an interface for rapidly exchanging articulatory and acoustic information and discuss implications for current models of speech.

“…Anecdotally, there are a number of widely experienced sensations that appear to involve both audition and touch (e.g., the physical sensation on your skin from hearing nails scratching on a chalkboard or an insect buzzing; Kitagawa & Spence, 2006). Supporting this observation, there is also evidence of a patient with a form of synaesthesia that results in auditory stimuli producing tactile sensations (Ro, Ellmore, & Beauchamp, 2013). This patient has a right ventrolateral thalmic lesion, which deprives her somatosensory cortex of normal somatosensory input.…”

Sensitivity to auditory‐tactile colocation in early infancy

An ability to detect the common location of multisensory stimulation is essential for us to perceive a coherent environment, to represent the interface between the body and the external world, and to act on sensory information. Regarding the tactile environment "at hand", we need to represent somatosensory stimuli impinging on the skin surface in the same spatial reference frame as distal stimuli, such as those transduced by vision and audition. Across two experiments we investigated whether 6- (n = 14; Experiment 1) and 4-month-old (n = 14; Experiment 2) infants were sensitive to the colocation of tactile and auditory signals delivered to the hands. We recorded infants' visual preferences for spatially congruent and incongruent auditory-tactile events delivered to their hands. At 6 months, infants looked longer toward incongruent stimuli, whilst at 4 months infants looked longer toward congruent stimuli. Thus, even from 4 months of age, infants are sensitive to the colocation of simultaneously presented auditory and tactile stimuli. We conclude that 4- and 6-month-old infants can represent auditory and tactile stimuli in a common spatial frame of reference. We explain the age-wise shift in infants' preferences from congruent to incongruent in terms of an increased preference for novel crossmodal spatial relations based on the accumulation of experience. A comparison of looking preferences across the congruent and incongruent conditions with a unisensory control condition indicates that the ability to perceive auditory-tactile colocation is based on a crossmodal rather than a supramodal spatial code by 6 months of age at least.
