  • Ictal EEG recorded at a sampling rate of 10kHz (Patient 1). (A) Ictal EEG shown using conventional filter settings (low-pass filter 120Hz, time constant 0.1s). Only 10 channels are shown. Ictal EEG shows initial spike burst at HI1–4/HS1–4 and spike-and-waves at A5–6, followed by electrodecremental pattern and low amplitude fast activities at HI1–3/HS1. Filled circle and straight line indicate the presence of VHFO. The EEG at B, C, and D is shown using VHFO filter settings. (B and C) Preictal VHFO detected visually using low-pass filter of 3kHz and time constant of 0.001s. Preictal VHFO of 1000–2500Hz are observed at HI1 and HI2 electrodes (underlined). They appear intermittently before the start of seizures, and are interrupted by spikes. The amplitudes are 3.5–22.1μV (note the calibrations), and the durations were 12–27ms. These activities are not observed at other electrodes. HFO of 350–550Hz are seen at HS1–2 and HI1–2 electrodes, with durations of HFO of 10–14ms and the amplitudes of 22.6–234.7μV. Representative HFO peaks are marked by triangles (B). (D) VHFO recorded at HI1, HI2 (both electrodes also record preictal VHFO) and HS1 electrodes become sustained at the start of seizure. The frequencies of VHFO are 1000–2000Hz and the amplitudes are around 8.8–14.1μV. These activities superimpose on the slower rhythmic activities (70–90Hz) (marked by triangles). Sustained VHFO lasted approximately 10s. Again, these activities are not observed at other electrodes, although rhythmic activities are recorded. ... Very high frequency oscillations

  • Brain regions showing significant group and frequency (slow-4 and slow-5) interaction effects on ALFF. ... The group and frequency (slow-4 and slow-5) interaction effects on ALFF. The regions showing significant group and frequency interaction effects on ALFF (hot colors): the left ventromedial prefrontal cortex (a), the left inferior frontal gyrus/precentral gyrus (b), and the bilateral posterior cingulate cortex/precuneus (c). The bar maps show the mean ALFF values for these regions. ... Low-frequency oscillation... Frequency dependence... Main effects of group and frequency on ALFF. (a) The group main effects on ALFF. Hot colors represent increased ALFF in the MDD group compared with HC, while the blue colors represent the opposite. (b) Frequency main effects on ALFF. Hot colors represent increased ALFF in the slow-5 as compared to slow-4 band, while the blue colors represent the opposite.
