Abstract(in English) | We elucidate the effect of dendritic backpropagating action potentials on neural interactions. First, we reduce a solvable oscillator model with passive dendrites to phase description. We elucidate that backpropagating action potentials change the stability structure of the system from monstability to bistability. Next, in simulations with the program NEURON, we derive phase response curves of a multi-compartment model with active dendrites. We demonstrate that this realistic model has also such bistability, and then, in the case of active dendrites, the interference between retrograde signal and synaptic input produces a large neural interaction. In such active dendrite models, we show that A-type K channels decrease a degree of interaction, but facilitate the bistability. |
