Functional and effective EEG connectivity patterns in Alzheimer’s disease and mild cognitive impairment: a systematic review by Elizabeth R. Paitel, Christian B. D. Otteman, Mary C. Polking, Henry J. Licht, Kristy A. Nielson, Kristy A. Nielson

“…An overarching pattern emerged of lower connectivity in both MCI and AD compared to healthy controls, which was most prominent in the alpha band, and most consistent in AD. In the minority of studies reporting greater connectivity, theta band was most commonly implicated in both AD and MCI, followed by alpha. …”

Abnormal dynamic features of cortical microstates for detecting early-stage Parkinson's disease by resting-state electroencephalography: Systematic analysis of the influence of eye... by G. Gimenez-Aparisi, E. Guijarro-Estelles, A. Chornet-Lurbe, D. Cerveró-Albert, Dongmei Hao, Guangfei Li, Y. Ye-Lin

“…However, scalp EEG microstate maps tend to underestimate the non-occipital or non-alpha-band networks, which can also be used to detect neuropathological changes. …”

Harmonizing the past: EEG-based brain network unveil modality-specific mechanisms of nostalgia by Hu Shuxiang, Hu Shuxiang, Liu Ying, Liu Ying, Yue Qizong, Yue Qizong, Zhao Huan, Zhao Huan, Zheng Maoping, Zheng Maoping

“…Additionally, nostalgia through the auditory channel induced higher activity intensity in the theta and gamma bands and increased brainwave amplitudes in the alpha bands. The audiovisual channel was capable of triggering stronger alpha-wave responses than the visual channel alone.DiscussionThese findings suggest that nostalgia effectively triggers positive emotional states and enhances cognitive processing. …”
