Do you think something like fMRI would have enough resolution? Can’t pick up activity directly of course, but perhaps by picking up fluid flow differentials?

- PetitPrince 6y agoAs mentioned by a sibling comment, fMRI have a sufficient spatial resolution (i.e. you can watch the activity of a few number of neuron at a time instead of grouping them by batch of hhundreds of them), but the temporal resolution is low (order of magnitude is seconds; a single action potential is 5ms). Here's a graph that summarize the temporal/spatial tradeoff of the different BMI tech: https://www.researchgate.net/figure/The-various-neural-recording-and-imaging-techniques-comparing-their-temporal-and-spatial_fig2_322549090 https://www.researchgate.net/figure/The-various-neural-recor...
