“Spot” center surround activation in 1680 detailed biophysical network model. Note the top square (slightly larger) over the band is the Golgi cell. With a short burst through mossy fibers, the cells in the center are first activated and then the periphery. The center detects burst on a broader band and emits bursts with shorter lag, higher frequency and longer duration [1]. We also simulated the “spot” on the AdEx spiking neuron based network model. The speed in Adex model (data not shown) and detailed biophysical model are different. However, AdEx network model could reproduce the spiking patterns whereas the detailed model could reproduce both firing and ionic channel properties such as extracellular evoked potentials (see Fig. 7).
