Simulation of Code Spectrum and Code Flow of Cultured Neuronal Networks

Instantaneous firing rate (poststimulus time histogram) where the sequence “1101” was observed. Since the timing becomes dispersed within trials, the peak positions and shapes gradually changed as time elapsed. Particularly, there was a tendency of risings and peaks to become faster than the regular timing, which is led by the fastest spike among the dispersed spikes as well as the slowest spike to be cancelled by the succeeding fastest negative spike (effectively supposed; pulling down the tail of peak), and lowering the peak height [16, 17].
