| Abstract(in English) | The previous studies have reported that the neural network model with connections following a lognormal distribution reproduces the irregular spontaneous activity. On the other hand, neurons exhibit rich evoked activities in vivo driven by sensory stimulus or top-down signals from higher cortical area. In this study, we reveal that the Teramae's model generates input driven gamma population oscillation. Moreover, when the inhibitory external inputs were injected to the model, there were firing-silent bistable regions in the input parameter space according to initial firing state. The bimodal membrane potential distribution was obtained under such conditions, and the model enables the physiologically reported up-down state. From these results, we can conclude that the SSWD model displays various evoked activities by the external input, and is biologically plausible. |
