According to Koenig et al., (2005), Alzheimer’s patients showed ______________________.: Decreased synchronization values in Alpha, Beta, and Gamma frequency bands, and increased global field synchrony values in the delta band.; High amplitude delta and theta activity, paired with low amplitude alpha and beta activity.; Disconnection between high density network nodes, indicating dysfunctiona resting state network connections.; Plaques and tangles in the top three layers of pyradimal neurons, creating low voltage beta activity and high amplitude delta activity.
