Figure 3: Traces of simulated membrane potentials of two selected neurons in the neuronal network from F ig. 2. Locations of neurons are indicated by X marks on the left. Panel A shows trace of neuron activated by the depolarizing current (frequency 7Hz, amplitude 0.25 mA) for 2 sec at the beginning of the simulation. Panel B shows the activity of a neuron locate d near the border of network for the time period coincident with panel A. Panel C shows an expanded view of the several bursts in 1 sec period from panel B.
