WebJul 23, 2024 · Introduction. The coupling between theta phase (4–12 Hz) and the amplitude of gamma (30–160 Hz) has been perhaps the most studied case of cross-frequency coupling between neuronal network oscillations to date [].This phase-amplitude coupling is thought to serve as a means of integrating locally generated gamma assemblies across … WebMar 30, 2024 · Effects of sTMS stimulation on brain function. On average, patients with MDD exhibit a pattern of highly synchronous theta and alpha activity seen broadly over most brain regions (A).The low-amplitude sinusoidal stimulation provided by the neodymium magnets rotating at the IAF entrains brain oscillatory activity to the frequency of stimulation for the …

WebApr 1, 2024 · A fundamental, yet unresolved, problem of modern neuroscience is how this coordination is achieved. One possibility is that neural oscillations at low- (theta, alpha) and high- (beta/gamma) frequency ranges facilitate the transient formation of large-scale networks that represent the neural correlates of a cognitive content or a motor program.
