Brain waves are a repetition of a pause and an activity

Abstract

Brain waves still cannot reliably distinguish between awake and asleep states. Here, I present new original indices, voltage subthreshold wave τ\tau and abovethreshold wave burst, for advanced LFP/EEG readings. Assuming that τ\tau is a microwave that fluctuates every sample such as the equipotential, the total number of τ\tau (NτN\tau) is inferred to be the maximum, and the amplitude of burst (Abst) is inferred to be the minimum. In fact, they invariably had a mean τ\tau duration (MτM\tau) of 2-3 sample intervals in any case. In addition, τ\tau and burst exhibited self-similarity for sample frequency while occupying approximately 30% and 70% of LFP in the natural state, respectively. Its threshold and Abst were correlated with the vigilance state and decreased to 70% by doubling the sample frequency. The dose of sevoflurane, which inhibits and synchronizes neural activity, was linearly correlated with decreases in the threshold and NτN\tau. Thus, τ\tau could reflect the uncertainty of the membrane potential. I propose that τ\tau and burst represent a pause and an activity such as the rhythm of the brain.
