The newer systems can sample much faster (10-100 Hz), but they're still limited by the fact that they're measuring a hemodynamic signal that lags behind neural activity.

Which other strong and weak forces could [photonic,] sensors detect?

IIUC, they're shooting for realtime MRI resolution with NIRS; to be used during surgery to assist surgery in realtime.

edit: https://en.wikipedia.org/wiki/Neural_oscillation#Overview says brainwaves are 1-150 Hz? IIRC compassion is acheivable on a bass guitar.
