Simulation of Code Spectrum and Code Flow of Cultured Neuronal Networks

Figure 6

Arrangement of 8 × 8 multi-electrodes on a simulated 2D mesh neural network. Each electrode acquires spikes of two to nine neurons. For example, “E9” showing 3 × 3 block of neurons (○) indicated with () shows that electrode () collects spikes from nine neurons. In addition, “E3” and “E4” are likewise; “E2” and “E5”–“E8”are not shown. Spectrum, cross-correlation, or probability distribution data obtained from electrode Em is expressed as “” in the text. Connections between eight neighboring neurons are randomly generated with given stochastic characteristics.
