| Research Abstract |
Isolated cortical neurons have known to respond to fluctuating inputs with high temporal precision about few milliseconds. The reliable responses of neurons, however, may be influenced local network structure in cortex. Here, we provided theories which clarify relationship between response reliability of neurons and potential factors including network structure, intrinsic properties of neurons, EPSP (excitatory-postsynaptic potentiation) distribution, and statistics of input signals. We have also reveals possible generation mechanism of fluctuating input to cortical neurons and computational role of them.
