Automating the sleep laboratory: Implementation and validation of digital recording and analysis

Diurnal Variation in Regional Brain Glucose Metabolism in Depression

“…Procedures for EEG sleep recording, monitoring, and data processing and definitions for visually scored sleep variables have been provided elsewhere (Doman et al 1995).…”

Electroencephalographic Sleep Profiles Before and After Cognitive Behavior Therapy of Depression

“…36 Four representative automated measures were used: the average delta count for the whole night, the delta ratio (a ratio of average delta counts from the first and second non-REM periods), the average REM counts for the whole night, and the average REM count for the first REM period. Four patients (2 at T 1 and 2 at T 2 ) had technically poor automated data that could not be used in the analyses.…”

Effects of Prior Fluoxetine Treatment on ? Sleep in Women with Recurrent Depression

“…Polysomnographic data were collected through Grass Model 78 amplifiers with filter settings of 100 Hz and 0.3 Hz for EEG and EOG, and 90 Hz and 10 Hz for EMG, and a sensitivity of 5 V/mm. Data were also digitized on-line at 256 Hz, recorded and stored on PCs as previously described (Doman et al 1995). Patients were not routinely screened for periodic limb movements or sleep apnea.…”

“…In addition, quantitative analyses of sleep data were conducted using period-amplitude analysis for EEG delta activity and a separate computer algorithm for identification of rapid eye movements during REM sleep (Doman et al 1995).…”
