«The results of the study show that the
planum temporale does not explain the rare but strong individual variability of the language domain that exists in humans and, therefore, can not be considered as a marker of language
asymmetry at individual level,» they stress.
Strikingly, the 3 regions showing positive correlations between CT and CSA
asymmetries were those known to exhibit robust
asymmetries across methodologies, such as the leftward asymmetrical
planum temporale and the rightward asymmetrical superior temporal sulcus and cingulate cortex.
