Prenatal evidence of left-right asymmetries in auditory evoked responses using fetal magnetoencephalography.
Auditory evoked responses between right- and left-hemispheric derivations were investigated in 53 recordings from fetuses in the third trimester using fetal magnetoencephalography (fMEG). The side-different latency development of the component P2pm suggests an earlier maturation of certain right than homologous left hemispheric brain areas during fetal brain development.
