Physicists studying the brain at Washington University in St. Louis have shown how measuring signals from a single neuron may be as good as capturing information from many neurons at once using big, expensive arrays of electrodes. The new work continues the discussion about how the brain seems to function in a “critical” state. The research was reported in the Journal of Neuroscience.
