Synchrony: Synchronous activity is defined as simultaneous EEG activity in homologous regions of each hemisphere. Synchrony is assessed during TA and NREM sleep. In well-established TA in healthy FT infants, the bursting activities between hemispheres occur almost simultaneously. In younger infants (32-38 weeks' postconceptional age), these bursts occur with less synchrony. In even younger PT infants (27-28 weeks' postconceptional age), the bursts of TD are synchronous between hemispheres.
