Event-Related Neural Oscillation Changes Following Reasoning Training in Individuals with Mild Cognitive Impairment.

Event-Related Neural Oscillation Changes Following Reasoning Training in Individuals with Mild Cognitive Impairment. Brain Res. 2018 Oct 17;: Authors: Mudar RA, Nguyen LT, Eroh J, Chiang HS, Rackley A, Chapman SB Abstract Emerging evidence suggests cognitive training programs targeting higher-order reasoning may strengthen not only cognitive, but also neural functions in individuals with Mild Cognitive Impairment (MCI). However, research on direct measures of training-induced neural changes, derivable from electroencephalography (EEG), is limited. The current pilot study examined effects of Gist Reasoning training (n=16) compared to New Learning training (n=16) in older adults with amnestic MCI on measures of event-related neural oscillations (theta and alpha band power) corresponding to Go/NoGo tasks during basic and superordinate semantic categorization. EEG data were recorded while participants performed the Go/NoGo task pre- and post-training, and power in theta and alpha frequency bands was examined. Both groups were comparable at pre-training on all measures and both groups showed greater event-related theta synchronization post-training. Furthermore, the Gist Reasoning group had enhanced event-related desynchronization in low-frequency alpha band (8-10 Hz) on response inhibition (NoGo) trials and high-frequency alpha band (11-13 Hz) on response execution (Go) trials during superordinate categorization, relative to the New Lear...
