Branching structure of a bistable dendrite

A branching structure consisting of three bistable cylindrical branches was considered. Both stable and unstable solutions for the voltage distributio n in such a structure, were obtained using the. method developed in our lab oratory. This made it possible to calculate the input current-voltage chara cteristic of the bistable branching structure, including unstable segments of this characteristic. Possible stable states of the structure when its pr oximal end is loaded by a resistance were determined. It is shown that the binary exclusive-OR Could be accomplished by the elementary branching struc ture of a bistable dendrite. A model with overexcitation carried out by Ca- dependent K channels was developed. It is shown that the model parameters d o not fall outside the physiological range of values.
