Fig. 26 - Top is the spontaneous <strong>EEG</strong> from O2. Bottom is the complex demodulation<br />
(JTFA) time series (x’ t ) of the instantaneous power between 25 - 30 Hz. Peaks in the<br />
JTFA time series represent integrations or the instantaneous envelope of burst activity in<br />
the hi-beta frequency b<strong>and</strong>. Bi-coherence between the two JTFA time series in fig. 20<br />
<strong>and</strong> fig. 21 measure the phase synchrony of burst activity in the theta <strong>and</strong> beta frequency<br />
b<strong>and</strong>s. Bi-phase measures the average time differences between theta <strong>and</strong> beta burst<br />
activity. Analyses were produced using the NeuroGuide Lexicor demo from the<br />
