Quanta Magazine(@QuantaMagazine):Cognitive neuroscientist Earl K. Miller describes neurons in the cortex as “Humpty Dumpty sitting on a wall,” teetering right on the edge of firing. Oscillating electrical activity can alter the voltage gradient at the synapses that connect neurons, making them more or less likely to fire in the future.
