Connectivity analysis of novelty process in habitual short sleepers

► Dynamic causal modeling is used to study impairments in short sleepers. ► 8 normal sleepers (NS) and 9 short sleepers (SS) participated in this study. ► ERP data was collected using the oddball auditory “IGNORE” and “ATTEND” tasks. ► Right-STG to right-IFG connection for NS was significantly different compared to SS. ► One week of extended time in bed was not enough to normalize impairments in SS.
