“…EEG Off-Line Analysis and Region of Interest (ROI) EEG data off-line analysis and ROI were previously described in details by ( Yu et al 2011). Briefly, all EG-data were filtered with a 0.5-100 Hz band pass filter off-line and were subjected to epoching (2-s each), linear-detrend, and artifact rejection (?80 lV) preprocessing.…”

The aim of this study was to investigate the effect of 400 ml whole blood donation on the human electroencephalogram (EEG) and hematology, not earlier reported in the literature. EEG activity was recorded from ten male blood donors (experiment group) before, during and after blood donation (i.e., 400 ml whole blood withdrawal). EEG topography and regional spectral field powers analyses were carried out via fast Fourier transformation. The venous hemoglobin (Hb) concentration was measured with a hematology analyzer. In the control investigation, 12 male age-matched volunteers (control group) were kept in semi-sitting position for the duration of a blood donation without actually vena puncture. The volunteers had no prior experiences of blood donation. Within the experiment group, post-donation Hb concentration decreased by 3.7% compared with the pre-donation Hb values (P < 0.01). Before blood donation, Hb concentration in control group was significantly higher compared to the experiment group (P < 0.05). For the experiment group, the field power of alpha-1 (7.5-9.5 Hz) EEG during blood withdrawal was significantly lower compared to that after blood withdrawal (P < 0.05). In contrast for the control group, all seven bands of regional spectral field powers showed no significantly discrepancies in the three periods. Blood donation attenuates the alpha-1 at the parietal-frontal area on human EEG-DMN transiently with no lasting effect at post-donation period. The blood donation-related effects on brain function may be of little consequence due to slight hemodynamic change and the results may facilitate the opinion that blood donation is a safe process and that should not discourage volunteers.

“…According to our previous research, when oxygen is inhaled for 20 min in a hyperbaric chamber, changes in patients' EEG microstates can be observed, reflecting the impact of HBO on brain function (Yu et al, 2011(Yu et al, , 2014. Referring to the research of Britz et al (2010), we analyzed the EEG microstates of 41 patients with DOC by applying a clustering algorithm to fit four microstate topographic maps before HBO therapy and 20 min after HBO therapy; these microstates were designated A, B, C and D (Figure 1).…”

Hyperbaric oxygen (HBO) therapy is an effective treatment for patients with disorders of consciousness (DOC). In this study, real-time electroencephalogram (EEG) recordings were obtained from patients with DOC during HBO therapy. EEG microstate indicators including mean microstate duration (MMD), ratio of total time covered (RTT), global explained variance (GEV), transition probability, mean occurrence, and mean global field power (GFP) were compared before and during HBO therapy. The results showed that the duration of microstate C in all patients with DOC increased after 20 min of HBO therapy (p < 0.05). Further statistical analysis found that the duration of microstate C was longer in the higher CRS-R group (≥8, 17 cases) than in the lower group (<8, 24 cases) during HBO treatment. In the higher CRS-R group, the transition probabilities from microstate A to microstate C and from microstate C to microstate A also increased significantly compared with the probability before treatment (p < 0.05). Microstate C is generally considered to be related to a salience network; an increase in the transition probability between microstate A and microstate C indicates increased information exchange between the auditory network and the salience network. The results of this study show that HBO therapy has a specific activating effect on attention and cognitive control in patients and causes increased activity in the primary sensory cortex (temporal lobe and occipital lobe). This study demonstrates that real-time EEG detection and analysis during HBO is a clinically feasible method for assessing brain function in patients with DOC. During HBO therapy, some EEG microstate indicators show significant changes related to the state of consciousness in patients with chronic DOC. This will be complementary to important electrophysiological indicators for assessing consciousness and may also provide an objective foundation for the precise treatment of patients with DOC.

Objective: Vertebral stenting is a valid treatment for posterior stroke. However, the outcome and prognostic factors in the Asian population of vertebral stent are not clear. This study was performed to investigate the quick effect and plasticity alterations of left vertebral artery stenting treatment and to explore the underlying electroencephalogram biomarkers for the prognosis. Method: Electroencephalogram default mode network activity, serum brain-derived neurotrophic factor, and basic neuropsychology estimations were obtained from nine male left vertebral artery stenosis patients who underwent left vertebral artery stenting 24 h before and after left vertebral artery stenting therapy. Result: The beta-1 (13–24 Hz) electroencephalogram field power of the pre–left vertebral artery stenting group was significantly higher compared to that of the post–left vertebral artery stenting and control group ( p < 0.05). The significant different standardized low-resolution brain electromagnetic tomography brain areas of beta-1 band Brodmann areas are 17R, 17L, 18R, 18L, 22R, 22L, 37R, and 37L. The nonliner lag ratio–based functional connectivity analysis showed global increase of connectivity in beta-1 standardized low resolution brain electromagnetic tomography network. Serum brain-derived neurotrophic factor did not show statistically significant changes during groups. Conclusion: Electroencephalogram default mode network provided a functional aspect of left vertebral artery stenting patients, and the beta-1 band power and distribution alterations could be candidate measurements for the plasticity alterations and prognosis evaluation.
