A mathematical model is proposed in order to describe, from the thermodynamic point of view, the changes in the photoreceptorcell membrane induced by light stimuli. The phenomenologicalbackground is the increase of the fly microvillar membrane ionicconductivity as a consequence of Ca(++-)Na(+) affinity modification under light action. On the basis of the analogywith the model of protein interaction in mixed solvents, themodel is focused on the selective interaction between ionchannels gates and two ionic ligands. Three possible theoretical cases are examined.
为了从热力学角度描述光刺激引起的光感受器细胞膜变化，提出了一个数学模型。现象学背景是在光作用下，果蝇微绒毛膜离子电导率因Ca(++-)-Na(+)亲和力改变而增加。基于与混合溶剂中蛋白质相互作用模型的类比，该模型聚焦于离子通道门与两种离子配体之间的选择性相互作用。研究了三种可能的理论情况。
