A fundamental feature of the human brain is the presence of both structural and functional asymmetries between two hemispheres at both macroscopic and microscopic dimensions. Previous studies have revealed the functional lateralization of language network. This kind of functional brain asymmetry was stable among different group of subjects. However, whether it is reliable in the same subject across time, which may be important to a few neuropsychiatric disorders, is still undetermined. In the present study, we examined the test-retest (TRT) reliability of the asymmetry of language network and prove its temporal stability.
