WebbWhen alpha slows and theta increases in frequency, it is often an indicator of pathologically slowed high-amplitude alpha, which is associated with Parkinson’s disease and cognitive decline. This indicates degradation of myelination and cell death in the cortex, and reflects growing metabolic inefficiency.

However, the effect of normal aging on these oscillations is not known, especially for elderly subjects (>49 years) for which AD is most prevalent. Webb17 feb. 2024 · While the power of the ripple band was relatively similar to control, the slow-γ band was increased in recordings from these mice. Multicellular imaging in 5xFAD mice crossed with Thy1-GCaMP6f mice, in which a calcium indicator is expressed in a subset of CA1 neurons, revealed differences in the ensembles of activated cells during SWR activity. small saltwater aquarium sharks

Webb7 dec. 2016 · We find that strong mutual inhibition between the interneuron populations permits distinct fast and slow gamma states, whereas weak mutual inhibition generates mixed gamma states. We develop... Webbgamma oscillations in both monkeys and humans (Murty et al., 2024), called slow [20-35 Hz] and fast gamma [36-66 Hz]. We estimated reliability of power in alpha and both gamma bands using a widely used measure called Intra Class Correlation (ICC; (Shrout and Fleiss, 1979)). We examined the test-retest reliability of SSVEPs at 32 Hz as well.
