“…Overall, results from this study suggest different responses in deaf "auditory" temporal areas for executive and language processing. We have previously observed these shared functions, describing an overlap between working memory and language processing in superior temporal areas of deaf adults (Cardin et al, 2020b). By understanding the developmental trajectories of these changes we can move towards a unified theory of crossmodal plasticity.…”

“…where these regions maintain their original computation but adapt to respond to a different sensory input (Lomber et al, 2010;Cardin et al, 2013;Bola et al, 2017;Benetti et al, 2017Benetti et al, , 2021. Other studies have suggested that sensory-deprived auditory regions are involved in higher-order cognitive functions, suggesting a functional change (see for a review Cardin et al, 2020b). Taking into account different mechanisms that can support all these findings…”

“…For example, previous studies have shown recruitment for visual working memory in the posterior superior temporal cortex (pSTC) of deaf individuals (Buchsbaum et al, 2005;Ding et al, 2015;Cardin et al, 2018), suggesting a change in function in this area from auditory to cognitive processing as a consequence of deafness. While crossmodal plasticity usually refers to the adaptation of sensory brain regions to processing information from a different sensory modality (Rauschecker, 1995(Rauschecker, , 2002Kral, 2007;Merabet and Pascual-Leone, 2010;Frasnelli et al, 2011;Heimler et al, 2015;Cardin et al, 2020aCardin et al, , 2020bRicciardi et al, 2020), these working memory responses in pSTC seem to suggest that in the absence of early sensory stimulation, a sensory region can change its function as well as the sensory modality to which it responds (Bedny, 2017;Cardin et al, 2020b). In addition, evidence suggests that auditory areas in deaf people are functionally connected to frontal regions involved in working memory, potentially being part of the same cortical network for EF and cognitive control (Ding et al, 2016;Cardin et al, 2018).…”

“…While crossmodal plasticity has been consistently found in higher-order auditory areas,), results from the primary auditory cortex are less consistent (see for a review Kral, 2007;Butler and Lomber, 2013;Cardin et al, 2020b). Using fMRI, somatosensory stimulation has been shown to strongly recruit primary auditory areas in deaf individuals (Karns et al, 2012), but activations elicited by visual tasks are generally modest or absent, and in many cases, differences between deaf and hearing groups are driven by deactivations in the hearing group (Karns et al, 2012;Scott et al, 2014;Cardin et al, 2016;Retter et al, 2019).…”

“…Cardin et al, 2020b), as well as considering different developmental trajectories can contribute to more dynamic accounts of plasticity that depart from the dichotomy of preservation or change of function. This could include considering our choice of frame of reference, as "change" or "preservation" is usually defined with the developed neurotypical adult brain as the normative or reference comparison point.…”

Crossmodal plasticity refers to the reorganisation of sensory cortices in the absence of their main sensory input. Understanding this phenomenon provides insights into brain function and its potential for change and enhancement. Using fMRI, we investigated how early deafness and consequent varied language experience influence crossmodal plasticity and the organisation of executive functions (EF) in the adult brain. Results from four visual EF tasks (working memory, switching, planning, inhibition) show that, as a function of the degree of deafness, deaf individuals specifically recruit 'auditory' regions during switching. This recruitment correlates with performance, highlighting its functional relevance. We also observed recruitment of auditory temporal regions during planning, but only in deaf individuals with the highest language scores, suggesting differential use of linguistic skills to support EF. Our results show executive processing in typically sensory regions, suggesting that the development and ultimate role of brain regions are influenced by perceptual environmental experience.

The linguistic counting system of deaf signers consists of a manual counting format that uses specific structures for number words. Interestingly, the number signs from 1 to 4 in the Belgian sign languages correspond to the finger‐montring habits of hearing individuals. These hand configurations could therefore be considered as signs (i.e., part of a language system) for deaf, while they would simply be number gestures (not linguistic) for hearing controls. A Fast Periodic Visual Stimulation design was used with electroencephalography recordings to examine whether these finger‐number configurations are differently processed by the brain when they are signs (in deaf signers) as compared to when they are gestures (in hearing controls). Results showed that deaf signers show stronger discrimination responses to canonical finger‐montring configurations compared to hearing controls. A second control experiment furthermore demonstrated that this finding was not merely due to the experience deaf signers have with the processing of hand configurations, as brain responses did not differ between groups for finger‐counting configurations. Number configurations are therefore processed differently by deaf signers, but only when these configurations are part of their language system.

Congenital sensory deprivation induces significant changes in the structural and functional organisation of the brain. These are well‐characterised by cross‐modal plasticity, in which deprived cortical areas are recruited to process information from non‐affected sensory modalities, as well as by other neuroplastic alterations within regions dedicated to the remaining senses. Here, we analysed visual and auditory networks of congenitally deaf and hearing individuals during different visual tasks to assess changes in network community structure and connectivity patterns due to congenital deafness. In the hearing group, the nodes are clearly divided into three communities (visual, auditory and subcortical), whereas in the deaf group a fourth community consisting mainly of bilateral superior temporal sulcus and temporo‐insular regions is present. Perhaps more importantly, the right lateral geniculate body, as well as bilateral thalamus and pulvinar joined the auditory community of the deaf. Moreover, there is stronger connectivity between bilateral thalamic and pulvinar and auditory areas in the deaf group, when compared to the hearing group. No differences were found in the number of connections of these nodes to visual areas. Our findings reveal substantial neuroplastic changes occurring within the auditory and visual networks caused by deafness, emphasising the dynamic nature of the sensory systems in response to congenital deafness. Specifically, these results indicate that in the deaf but not the hearing group, subcortical thalamic nuclei are highly connected to auditory areas during processing of visual information, suggesting that these relay areas may be responsible for rerouting visual information to the auditory cortex under congenital deafness.
