I can't speak for your brain lighting up. But you may find some useful information about visualizing electromagnetic radiation within the visible spectrum from this thread:fredreload said:Yes well, I've been thinking about ways to visualize the actual electrical synapses inside a person's head. Well, I got an idea of lighting up the sodium ion with wavelength 589nm, or the solar roof technique, but both requires looking inside the brain. I swear I saw my brain light up one night, I'm just not sure how people retrieve that signal(through the eyes?). We know MRI can retrieve radio signal because it passes through, but the resolution is low. So, I'd like some idea on how to visualize electrical synapses
