For decades, neuroscientists have focused on neuron firing—tiny "spikes" of voltage—as the way information is transmitted in the brain. These spikes are thought to play a foundational role in generating…
I had an anatomy instructor who insisted that neural activity was a purely chemical process and that the electromagnetic stuff was just a byproduct that got all the attention because it was easy to detect. His central argument was that nerve transmission speeds are no faster than 150m/s which is somewhat slower than the speed of light you’d expect if neurons were little wires transmitting signals.
