Introduction to Eeg Phase

What is/are Eeg Phase?

Eeg Phase - First, the EEG phase synchronization indexes (PSI) of all channel pairs are estimated as features to distinguish different emotions, since certain topographical maps on PSI reveal specific emotion states. ^[1] We compared brain functional connectivity between the two groups by computing EEG phase synchrony during HRI session. ^[2] To develop more effective vibration stimulus methods for consistently enhancing MI, this study proposes an EEG phase-dependent closed-loop mechanical vibration stimulation method. ^[3] MAIN RESULTS Our method showed higher accuracy in predicting the EEG phase than the conventional autoregressive model-based method. ^[4] The results indicated that there were frequency-dependent effects in the relationships between the EEG phase resetting and reaction time. ^[5] This revealed a direct link between 4 Hz EEG phase and power prior to the stimulus and the phase of the rhythmic component of these perceptual weights. ^[6] We demonstrate that the performance of our method shows higher accuracy in predicting the EEG phase than the conventional autoregressive model-based method. ^[7] Cerebral‐acoustic coherence (CACoh) measured EEG phase locking with stimuli envelopes. ^[8] Results TMS led to EEG phase synchronization and evoked time-averaged potentials which were, however, comparable to the effects of peripheral, somatosensory stimulation, especially when combined with auditory stimulation. ^[9] We managed to introduce a new way to analyze EEG phase space. ^[10] To address this question here, we presented word–nonword pairs, each of which was visible for 5 s and measured the effect of EEG phase during stimulus onset on later memory recall. ^[11] Results TMS led to EEG phase synchronization and a pattern of evoked potentials which were comparable with those patterns evoked by sham-stimulation. ^[12] Patients received the TBS treatment every morning, 5 days a week for 1 month, and were clinically and electrophysiologically evaluated (EEG phase synchronization and coherence) before, immediately after (T0), and one (T1), three (T3) and six (T6) months after the end of the TBS treatment. ^[13] Remarkably, the correlation between EEG phase and behavioural report occurred in the absence of concomitant changes in EEG amplitude. ^[14] On representative channels over the cortices encoding the execution information of reaching movements, we show that the low-delta EEG phase representation is characterized by higher signal-to-noise ratio and stronger modulation by the movement tasks, compared to the low-delta EEG amplitude representation. ^[15] The EEG phase space is reconstructed, and some new geometrical features are extracted. ^[16] We further propose a new robust algorithm for delivering real-time EEG phase-specific stimulation based on short prerecorded EEG training data (Educated Temporal Prediction). ^[17] Tests of the instrument with three healthy adults indicate that EEG phase-locked TMS can be administered accurately enough to start testing systematically whether specific stimulation protocols can lead to clinically significant improvements in depression. ^[18] The work presented in this paper extracts the EEG phase synchrony feature called Phase Lock Value (PLV) to decode Motor Imagery (MI) of center-out hand movement in right and left directions. ^[19] OBJECTIVE The objective of this study was to investigate EEG phase clustering in response to transcranial magnetic stimulation (TMS), compare it with photic stimulation in controls, and explore its potential as a biomarker of genetic generalized epilepsy or migraine with aura. ^[20]

eeg phase synchronization

First, the EEG phase synchronization indexes (PSI) of all channel pairs are estimated as features to distinguish different emotions, since certain topographical maps on PSI reveal specific emotion states. ^[1] Results TMS led to EEG phase synchronization and evoked time-averaged potentials which were, however, comparable to the effects of peripheral, somatosensory stimulation, especially when combined with auditory stimulation. ^[2] Results TMS led to EEG phase synchronization and a pattern of evoked potentials which were comparable with those patterns evoked by sham-stimulation. ^[3] Patients received the TBS treatment every morning, 5 days a week for 1 month, and were clinically and electrophysiologically evaluated (EEG phase synchronization and coherence) before, immediately after (T0), and one (T1), three (T3) and six (T6) months after the end of the TBS treatment. ^[4]

eeg phase space

We managed to introduce a new way to analyze EEG phase space. ^[1] The EEG phase space is reconstructed, and some new geometrical features are extracted. ^[2]

eeg phase synchrony

We compared brain functional connectivity between the two groups by computing EEG phase synchrony during HRI session. ^[1] The work presented in this paper extracts the EEG phase synchrony feature called Phase Lock Value (PLV) to decode Motor Imagery (MI) of center-out hand movement in right and left directions. ^[2]
