Figure 2.
Examples of extracted time series. Time series from top to bottom are: tachograms (BBI); systograms (SYS); the mean power PEEG(i) of the BBI-related EEG intervals EEG(i); and the mean power PEEGδ(i) of the BBI-related EEG-delta band intervals EEGδ(i) from a control subject (a), and a patient with paranoid schizophrenia (b). Note the typical lower variability in BBI sequences and the lower mean power PEEG and PEEGδ in the patient suffering from paranoid schizophrenia. The plot scaling of the PEEGδ(i) time series was different to guarantee for a higher degree of visual clarity.
