M-sequence family from cultured neural circuits

摘要

We have already shown its feasibility by computer simulations that show a loop circuit can be copied to another area by back-propagation leaning algorithm; this is a key function of brain intelligence, which includes functions such as memory, association, reasoning, and abstraction. We also have found M-sequences in spike trains of cultured neuronal networks. In this paper, we report that we found family or fragment of M-sequence responses also in the instantaneous firing rates (PSTH's) from cultured neural networks of published data and our own data, which suggest the existence of loop circuits with a feedback link composed of 3 to 5 neuron cells or equivalent circuits.
