Abstract(in English) | It has been observed that action potentials generated at the axon are propagated through the soma and dendrite reversely. We analyzed two neural oscillator models which mimic the action potential invasion upon the dendrite. One is a solvable model that enable us to extract the effect of the dendritic backpropagation only. The other is a realistic model with Type I membrane oscillators. We compared invasion case and non-inversion case in both two models, and then, we demonstrated that at the synapse, a collision of excitation waves from pre-synapse neuron with excitation ones back-propagated through the dendrite of post-synapse neuron induces bistable states which consist of in-phase locking and anti-phase one. Such kind of the bistability causes the multiple phase clustering of the neural population. The phase clustering is one of cogent hypothesis for information representation binding distributed codes in the brain. |
