There is some evidence, mostly fMRI-based as far as I'm aware, of slow (~10s period) fluctuations between functional coupling of brain regions on a macroscopic level. The associated networks are often referred to as resting state or default-mode networks. See e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3596417/ I am not aware of 15-40s period transitions that are "accompanied by transitions of levels of consciousness", but would be interested in case anyone knows what these refer to. |
