Hello! Because we see significant changes in CSF that can be induced by respiration, and meditation is known to decrease the frequency of respiration, I would expect there to be significant effects of CSF flow with meditation [1]. Beyond this, we know that with individuals who are good at meditating seem to induce theta waves in EEG [2]. Because there is a coupling between EEG/fMRI global hemodynamic signal/CSF flow, I would also expect there to be a change in CSF that may be coupled with the EEG rhythms. 1. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3895787/pdf/2045-8118-10-36.pdf https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3895787/pdf/204... 2. https://pubmed.ncbi.nlm.nih.gov/19922249/ https://pubmed.ncbi.nlm.nih.gov/19922249/
