How supramodal is the language network? The view from sign language


One of the major insights of modern linguistics has been that the human capacity for language is not bound to speech but may also be externalized and perceived in the visuo-spatial modality of sign language. Neuroimaging evidence indicates that signed, spoken and, written language is processed in a partially overlapping primarily left-hemispheric fronto-temporal network (Trettenbrein et al., 2021, Human Brain Mapping). Against this background, this talk will review to what extent and on what grounds anatomical and functional components of the language network can or should reasonably be considered supramodal.
