Amplitude and Phase Analysis of EEG Signal by Complex Demodulation
Analysis of amplitude and phase characteristics for delta, theta, and alpha bands at localized time instant from EEG signals is important for the characterizing information processing in the brain. In this paper, complex demodulation method was used to analyze EEG (Electroencephalographic) signal, particularly for auditory evoked potential response signal, with sufficient time resolution and de...

متن کاملAutomatic Sleep Spindle Detection with EEG Based on Complex Demodulation Method and Decision Tree Model
Sleep spindle is the characteristic waveform of electroencephalogram (EEG) which is important for clinical diagnosis. In this study, an automatic sleep spindle detection method was developed. The EEG signals were recorded based on the standard polysomnogram (PSG) measurement. A preprocessing procedure is introduced to exclude the unnecessary data segments and normalized the necessary data segme...
متن کاملSuicide Seasonality: Complex Demodulation as a Novel Approach in Epidemiologic Analysis
BACKGROUND Seasonality of suicides is well-known and nearly ubiquitous, but recent evidence showed inconsistent patterns of decreasing or increasing seasonality in different countries. Furthermore, strength of seasonality was hypothesized to be associated with suicide prevalence. This study aimed at pointing out methodological difficulties in examining changes in suicide seasonality. METHODODOL...
متن کاملComplex demodulation of cardiorespiratory dynamics preceding vasovagal syncope.
BACKGROUND The dynamic autonomic processes leading to vasovagal syncope are poorly understood. METHODS AND RESULTS We used complex demodulation to continuously assess changes in respiration, R-R interval, and arterial pressure (blood pressure) variability during 60 degree head-up tilt in 25 healthy subjects with tilt-induced vasovagal syncope and 25 age-matched nonsyncopal control subjects. C...
