Table 1. Participants with In-scanner Sleep-stage Monitoring.

Seven subjects participated in this study, ranging in age from 24 to 58 months.

Age = post-natal months. All seven subjects contributed to sleep-stage analysis. All seven participants underwent in-scanner sleep-stage monitoring with EEG, EOG and video monitoring. Acquisition time = minutes of fMRI data acquired in NREM3 sleep for Session 1 (S1) and Session 2 (S2). Sessions = number of scanning session per child. Sequences = number of image-acquisition epochs initiated per child. Arousals = number of confirmed arousals, either brief (B) or full (F). Arousal Cause = cause of full arousals, where P = subject preparation; ASL = ASL pulse-sequence acquisition; T2* = T2* pulse-sequence acquisition.

^†= subject excluded from ICN analysis due to insufficient T2* data.
