One of the most important but challenging questions in neuroscience is how early language experience affects the language-ready brain function and anatomy, i.e., the development of dorsal and ventral streams in the left-hemisphere language network, as spoken language is ubiquitous in the environment of hearing infants. Congenitally profoundly deaf children born into hearing parents often do not receive functional language input until they receive special services or interact with other deaf individuals who use sign language. This presents a unique opportunity to explore how early language experience changes the language-ready brains becoming language-using brains. Here we recruited and compared functional and structural brain data from the following three groups:(1)congenitally profoundly deaf adults(n=31) with rare early sign language experience(congenitally deaf non-native signers, CDNN);(2) congenitally profoundly deaf adults(n=29) who were native signers of Chinese sign Language(congenitally deaf native signers, CDN);(3) hearing speakers(Hs)(n=31). Without early language input, compared with CDN and Hs, CDNN has changed functional connectivity strength(FCs), that is, decreased FCs in left inferior frontal gyrus(Broca’s area) but increased FCs in left angular gyrus(geschwind’sarea), in the dorsal pathway, but not in the ventral pathway. Furthermore, when performing a passive sign language comprehension task, CDNN also activated less in dorsal part of left inferior frontal gyrus compared with CDN and Hs. More important, CDN showed similar FCs and activation pattern as Hs, suggesting general modality-independence of the core language network plasticity in the dorsal pathway might be affected purely by early language experience. We further find the part of superior longitudinal/arcuate fasciculus(sLF/AF) in posterior superior temporal gyrus(Wernicke’s area)showed significantly enhanced fractional anisotropy(FA) in CDNN compared to CDN and Hs,providing a possible str
