In anaesthetized cats the role of the medullary reticular formation in discriminative functions was studied. We analysed (1). variability of collective reactions of the reticular neurons (extracellular potential gradients recorded bipolarly in three directions by a tetrad of micropipettes with closely-positioned tips in a small volume of the reticular formation) to the same stimulus, and (2). reactions to heterotopic stimuli. The pattern of the potential gradients generated by the stimulation (electrical, natural) of the same spot on the body surface was constant during the time periods studied (up to 30 min). Responses evoked from reciprocally remote receptor areas were manifestly different, at least in one of the depth profiles investigated. It can be concluded that the reticular formation, through its reactions, can differentiate heterotopic stimuli; in this respect it does not operate as a 'nonspecific' system.
在麻醉猫身上，研究了延髓网状结构在辨别功能中的作用。我们分析了：（1）网状神经元的集体反应（通过四极微电极在小体积网状结构中从三个方向双极记录细胞外电位梯度）对相同刺激的变异性，以及（2）对异位刺激的反应。在研究期间（长达30分钟），体表同一点受到刺激（电刺激、自然刺激）所产生的电位梯度模式是恒定的。从相互远离的感受器区域诱发的反应明显不同，至少在所研究的深度剖面之一中是如此。可以得出结论，网状结构通过其反应能够区分异位刺激；在这方面，它并非作为一个“非特异性”系统起作用。
