Such findings had no counterparts in the right hemisphere, and the subject's handedness and sex were found to have no significant effect or interaction with FS on the left PT size.  ...  The FS1 subjects also exhibited increased gray matter volume, reduced hemispheric gray matter leftward asymmetry, and, in LHs, reduced strength of hand preference.  ...  Indeed, we previously reported that brain volume interacts with handedness and left PT surface on the interindividual variability in the functional lateralization for language comprehension and production  ...

2020 Journal of Neuroscience  
, lateralisation for language comprehension was highly variable across individuals, and (ii) with increasing non-native language proficiency, reading and speech comprehension displayed substantial changes  ...  A multi-pronged analytic approach revealed converging evidence for striking differences in hemispheric specialisation and plasticity between the language systems.  ...  Thus, the convergent results in the present work indicate that interindividual variability in lateralization for language comprehension is not an artifact of task or methodology, but that instead, language  ...
