Transmission of the reticulofugal activity via the interneurons localized in the ventromedial grey matter of the lumbar region and monosynaptically activated from the reticulospinal fibres was studied in anaesthetized immobilized cats. Interneurons usually generated stationary discharges when reticulospinal pathways were rhythmically stimulated with relatively low frequencies (up to 80-100/s); with further increase of stimulation frequency the discharges became non-stationary (initial high-frequency phase was followed by partial or complete discharge suppression). Maximal firing rate at the initial phase could not exceed 180-230 imp./s. The "transfer function" (the ratio of response frequency to stimulation frequency) reached 0.7-0.8 at low stimulation frequencies and decreased substantially at higher ones. Using mathematical modelling of the excitatory and post-activation inhibitory actions in these neurons, the parameters have been estimated which determine the transfer properties, of the interneuronal population relaying reticulofugal activity.
在麻醉固定的猫身上，研究了通过位于腰段腹内侧灰质中的中间神经元传递网状离心活动的情况，这些中间神经元由网状脊髓纤维单突触激活。当以相对较低频率（高达80 - 100次/秒）有节奏地刺激网状脊髓通路时，中间神经元通常会产生平稳放电；随着刺激频率进一步增加，放电变得不平稳（最初的高频阶段之后是部分或完全放电抑制）。初始阶段的最大放电频率不超过180 - 230次/秒。在低刺激频率下，“传递函数”（反应频率与刺激频率之比）达到0.7 - 0.8，而在较高频率下则大幅下降。通过对这些神经元中兴奋性和激活后抑制作用进行数学建模，估计了决定传递网状离心活动的中间神经元群体传递特性的参数。
