Existence of an optimum radius of fibre is shown, when physical parameters of the intracellular medium and the nonexcitable dendritic membrane are determined and the length and load resistances are fixed. It provides the maximum potential for one end of the fibre if synaptic conductance is determined for another one. Conductance of excitation along the dendritic fibre of changing thickness is optimum for little synaptic conductance when the fibre radius increases and for high conductance when the radius decreases. The formula for calculating an optimum dendritic spine neck radius is proposed.
当确定细胞内介质和非兴奋性树突膜的物理参数，且长度和负载电阻固定时，显示出存在纤维的最佳半径。如果确定了另一端的突触电导，则可为纤维的一端提供最大电位。当纤维半径增加时，对于小的突触电导，沿厚度变化的树突纤维的兴奋传导最佳；而当半径减小时，对于高电导则最佳。提出了计算最佳树突棘颈半径的公式。
