Scalp and Source Power Topography in Sleepwalking and Sleep Terrors: A High-Density EEG Study.

ABSTRACT:

Study objectives

To examine scalp and source power topography in sleep arousals disorders (SADs) using high-density EEG (hdEEG).

Methods

Fifteen adult subjects with sleep arousal disorders (SADs) and 15 age- and gender-matched good sleeping healthy controls were recorded in a sleep laboratory setting using a 256 channel EEG system.

Results

Scalp EEG analysis of all night NREM sleep revealed a localized decrease in slow wave activity (SWA) power (1-4 Hz) over centro-parietal regions relative to the rest of the brain in SADs compared to good sleeping healthy controls. Source modelling analysis of 5-minute segments taken from N3 during the first half of the night revealed that the local decrease in SWA power was prominent at the level of the cingulate, motor, and sensori
