EEG/EOG/EMG data from a cross sectional study on psychophysiological insomnia and normal sleep subjects

Abstract

The data presented here had been originally collected for a research project entitled 'Sleep EEG spectral analysis in psychophysiological insomnia and normal sleep subjects'. This article describes the data of 11 subjects, referred to Sleep Disorders Research Center (SDRC) in Kermanshah, Iran. The data includes 14 EEG, 6 EOG, and 3 EMG channels, with a sampling ratio of 256 Hz. It includes power spectral features in segments of 30 s for each channel, and nonlinear analysis parameter. Also, the complete demographic and polysomnography specifications are attached.

Keywords: EEG; Insomnia; Psychophysiological; Sleep dataset.

6 EEG channels sampled at 256 Hz using SOMNOscreen PSG (SOMNOscreen TM plus PSG+, SOMNOmedics GmbH, Germany). This shows the voltage in microvolts on each channel referenced to the left or right earlobe (A1, A2) over a 4 s window.

A typical Poincare plot. The horizontal axes demonstrate the illustrating the statics result at a specific epoch (x(k)) and the vertical axis illustrating the statics result after a specified epoch delay (x(k+1)). An ellipse is fitted to the data points and the Poincare plot descriptors are measured by estimating the SD perpendicular to the diametric line was defined as SD₁, and the SD along the diametric line was defined as SD₂ and ratio of the SD₁/SD₂ of the fitted ellipse.
