| Abstract(in English) | We propose a neuronal network model that is made of three dynamic systems: neuron-dynamics, synapse-dynamics and neurotransmitter-dynamics. The model consists of a cortical neuron (CN) network and a locus coeruleus (LC) network. Depending on neuronal activity, LC neurons release neurotransmitter norepinephrine (NE) into the CN network. We let the CN network carry out feature recognition tasks. When the CN network recognized an input feature, a certain cell ssembly relevant to the input feature was selectively activated. NE release into the CN network enhanced the cognitive performance of the CN network. The key process for the enhancement of the performance was the amplification of the membrane potentials of the CN neurons under the ongoing spontaneous neuronal activity state. |
