abstract = {AbstractEarly auditory deprivation leads to a
reorganization of large-scale brain networks involving and
extending beyond the auditory system. It has been documented
that visuomotor transformation is impaired after early
deafness, associated with a hyper-crosstalk between the
task-critical frontoparietal network and the default-mode
network. However, it remains unknown whether and how the
reorganized large-scale brain networks involving the
auditory cortex contribute to impaired visuomotor
transformation after early deafness. Here, we asked deaf and
early hard of hearing participants and normal hearing
controls to judge the spatial location of a visual target.
Compared with normal hearing controls, the superior temporal
gyrus showed significantly increased functional connectivity
with the frontoparietal network and the default-mode network
in deaf and early hard of hearing participants, specifically
during egocentric judgments. However, increased superior
temporal gyrus-frontoparietal network and superior temporal
gyrus-default-mode network coupling showed antagonistic
effects on egocentric judgments. In deaf and early hard of
hearing participants, increased superior temporal
gyrus-frontoparietal network connectivity was associated
with improved egocentric judgments, whereas increased
superior temporal gyrus-default-mode network connectivity
was associated with deteriorated performance in the
egocentric task. Therefore, the data suggest that the
auditory cortex exhibits compensatory neuroplasticity (i.e.
increased functional connectivity with the task-critical
frontoparietal network) to mitigate impaired visuomotor
transformation after early auditory deprivation.Keywords:
