刺激と因果性のニューロン間伝達の数理モデル : シナプスにおける2つのポテンシャルバリアの記述による同期化,脱同期化機構のモデル  [in Japanese] A mathematical model of the inter neuronal transmissions of signals and causalities : A model which describes the 2-potential barriers on synapse, with synchronizing and de-synchronizing mechanisms  [in Japanese]

脳の局部電位から励起された空間モードと位相の状態を調べ,刺激の受け手側と送り手側で位相の特性が異なることを示す.この観点から,一つのシナプスの前後にその内因性によって相互に引き込みが起こり得るという一つの仮説を置く.刺激の受け手側から送り手側に位相を引き込む信号が不安定に作用するモデルを組み立てる.シナプス前後においてポテンシャルバリアを定義し,後膜部には不安定な開口放出機構を仮定する.シナプス前後で局部的なエネルギー発生によってシナプス小胞活性の制御因子か開放され,それが位相の引き込みに関わるバリアに作用し,発火の因果性か伝えられる.

Different phenomena are found in the phase characteristics between pre-synapse neuronal activities and post-synapse activities, that is observed from human EEG, appeared in the states of its spacial mode and the instantaneous alternations of phase states. It is assumed that there would be a mutual interaction by the internal mechanism between two neurons, passing through the only one synapse. We put forward a model, in which the event is caused by making the synaptic connection temporally and spontaneous1y, that is the trigger of the mutual interaction on phase states with transmitting a signal from the post-synapse to pre-synapse. Two potential barriers are described on the synapse, with being supposed that the opening and emitting mechanism for transmitters a1so exists in the post-synapse. If the energy is 1ocally induced, the control factors related to the activities of synaptic vesiculars are released, this factor acts on the barriers and the causality over neuronal activities are spontaneously emerged.
