Влияние деполяризации мембраны нейронов супрахиазматического ядра на спайковую активность in vitro

Abstract

На переживающих срезах гипоталамуса крыс исследованы особенности спайковой активности нейронов супрахиазматического ядра в условиях деполяризации их мембраны in vitro. Деполяризация мембраны приводила к росту активности клеток и снижению энтропии логарифма распределения межспайковых интервалов, являющейся мерой нерегулярности генерации спайков. Обсуждаются возможные механизмы, лежащие в основе данных эффектов.

The properties of spike activity of neurons of the suprachiasmatic nucleus during their membrane depolarisation in vitro are investigated on rat hypothalamic slices. Depolarisation of membrane caused an increase in activity of cells and a decrease in entropy log interspike interval distribution were used as a measure of spikes irregularity generation. Possible mechanisms of the effects are discussed.
