Siyuan Zhou, Shi Chen, Shuang Wang, Qingbai Zhao, Zhijin Zhou, Chunming L. Temporal and Spatial Patterns of Neural Activity Associated with Information Selection in Open-ended Creativity. Neuroscience. vol 371. 2018-11-09. PMID:29247775. |
the results showed that (1) novel solutions induced a higher lower alpha power in the temporal area, which might be associated with the automatic, unconscious mental process of retrieving extensive semantic information, and (2) upper alpha power in both frontal and temporal areas and frontal-temporal alpha coherence were higher in novel solutions than in normal solutions, which might reflect the selective inhibition of semantic information. |

finally, interpretation of the results has led us to propose two distinct physiological mechanisms for defense: one, unconscious defense, by alpha synchronization in connection with the drive derivatives, and another, repression, based on the indications of reality in connection with the ego. |

[An Assessment Method of Electroencephalograph Signals in Severe Disorders of Consciousness Based on Entropy]. Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi. vol 33. issue 5. 2018-06-15. PMID:29714932. |
this paper explores a methodology used to discriminate the electroencephalograph(eeg)signals of patients with vegetative state(vs)and those with minimally conscious state(mcs).the model was derived from the eeg data of 33 patients in a calling name stimulation paradigm.the preprocessing algorithm was applied to remove the noises in the eeg data.two types of features including sample entropy and multiscale entropy were chosen.multiple kernel support vector machine was investigated to perform the training and classification.the experimental results showed that the alpha rhythm features of eeg signals in severe disorders of consciousness were significant.we achieved the average classification accuracy of 88.24%.it was concluded that the proposed method for the eeg signal classification for vs and mcs patients was effective.the approach in this study may eventually lead to a reliable tool for identifying severe disorder states of consciousness quantitatively.it would also provide the auxiliary basis of clinical assessment for the consciousness disorder degree. |

especially for raw eeg contaminated by artifacts, when the bis index is used to indicate the consciousness level, the improvement is 7.37% (p < 0.05), 9.04% (p < 0.05), 18.46% (p < 0.05), 27.73% (p < 0.05), 14.65% (p < 0.05), 2.52%, 5.38% and 6.24% (p < 0.05) for relative alpha and beta power, power ratio, total power, mf, sef, re and se, respectively. |

Seul-Ki Yeom, Dong-Ok Won, Seong In Chi, Kwang-Suk Seo, Hyun Jeong Kim, Klaus-Robert Müller, Seong-Whan Le. Spatio-temporal dynamics of multimodal EEG-fNIRS signals in the loss and recovery of consciousness under sedation using midazolam and propofol. PloS one. vol 12. issue 11. 2017-11-22. PMID:29121108. |
once consciousness was lost via sedatives, we observed gradually increasing eeg power at lower frequencies (<15 hz) and decreasing power at higher frequencies (>15 hz), as well as spatially increased eeg powers in the delta and lower alpha bands, and particularly also in the upper alpha rhythm, at the frontal and parieto-occipital areas over time. |

specifically, oscillations in the alpha frequency range (alpha rhythms) are prevalent in the awake, conscious brain and play an important role in supporting perceptual, cognitive, and social processes. |

PMID:26408799. |
in addition, we show for the first time for the auditory modality that local excitability, measured by decreased alpha power in the auditory cortex, increases prior to conscious percepts. |

Magnetoencephalographic alpha band connectivity reveals differential default mode network interactions during focused attention and open monitoring meditation. Frontiers in human neuroscience. vol 8. 2014-10-31. PMID:25360102. |
our findings showed a state dependent coupling of posterior cingulate cortex (pcc) to nodes of the dmn and of the executive control brain network in the alpha frequency band (8-12 hz), related to different attentional and cognitive control processes in fa and om meditation, consistently with the putative role of alpha band synchronization in the functional mechanisms for attention and consciousness. |

furthermore, the difference in neural interactions between conscious and unconscious states could be represented in 4 frequency-specific large-scale networks with unique interaction patterns: 2 networks were related to consciousness and showed peaks in alpha and beta bands, while the other 2 networks were related to unconsciousness and showed peaks in theta and gamma bands. |
