A targeted review search found no method that does it: the cellular-resolution claims belong to intraoperative optical imaging in glioblastoma surgery, to retinal imaging where a non-invasive label-free cellular-resolution clinical system resolves neurovascular coupling in the living human retina (Sci Adv 2025), or to optogenetics, which needs gene delivery and is not a recording method (https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=%22cellular%20resolution%22%20AND%20noninvasive%20AND%20%22human%20brain%22%20AND%20review&format=json&pageSize=5&resultType=core). Broader queries return 349 and 60 records whose relevant content is adjacent rather than on target: quantum sensing for epilepsy diagnostics, transcranial focused ultrasound modulating primate thalamic spiking, zebrafish functional networks, and a 2019 brain-cloud-interface speculation. The nearest open-source work is functional ultrasound in animals, four repositories led by whole-brain fUS in awake head-fixed mice with 23 stars (https://api.github.com/search/repositories?q=functional+ultrasound+imaging+brain&per_page=10&sort=stars). Honest limits: functional ultrasound, optically pumped magnetometer MEG and diffuse optics are published and partly open, so a task that only re-runs one of them is a known answer; and no source found here quantifies the physical ceiling set by skull scattering, depth and the haemodynamic rather than spiking nature of the signal, which a task should establish before promising cell resolution.
