Impaired posterior cingulate cortex–parahippocampus connectivity is associated with episodic memory retrieval problems in amnestic mild cognitive impairment

European Journal of Neuroscience, Volume 53, Issue 9, Page 3125-3141, May 2021., 2021
We show that parahippocampus and posterior cingulate cortex interact via θ–γ coupling that correlates with memory recollection, but this is altered in amnestic mild cognitive impairment patients. Hence, this study revealed novel information concerning concomitant oscillations and differences in a network centered on the posterior cingulate cortex in ...

Global EEG coherence as a marker for cognition in older adults at risk for dementia

Psychophysiology, Volume 57, Issue 4, April 2020., 2020
Abstract Quantitative electroencephalography (EEG) provides useful information about neurophysiological health of the aging brain. Current studies investigating EEG coherence and power for specific brain areas and frequency bands have yielded inconsistent results. This study assessed EEG coherence and power indices at rest measured over the whole skull
