This video shows neural activity recorded from a slice of rat cortex (top) and simulated neural activity from three versions of a model calculated from that activity (bottom). The colors represent changes in voltage in the real or simulated neural tissue. In this case, the cortex (top) spontaneously exhibited a spiral pattern of activity. The bottom three movies show three different aspects of the actual neural activity captured by the model. Scientists hope that by learning to mimic those patterns, some of which mimic certain characteristics of a seizure, they can find better ways to inhibit it.
