An anatomicophysiological analysis was made to elucidate afferent connections of the neurons in the Forel's field of H (FFH) by horseradish peroxidase retrograde tracing technique and by evoked potential technique.1) The FFH neurons receive fibers from the neocortex (layerV) and brainstem reticular formations.2) Physiological projections from the mesencephalic reticular formation to the FFH as well as to the motor cortex were ipsilateral, but those from the pons and medulla oblongata were bilateral.3) These data will suggest that the FFH neurons are in junction of the corticoreticular connections and play an important role in the maintenance of an epileptic excitability of the neocortical system as suggested by Jinnai and Mukawa.

通过辣根过氧化物酶逆行示踪技术和诱发电位技术进行解剖生理学分析，以阐明 Forel 区 H (FFH) 神经元的传入连接。1) FFH 神经元接收来自新皮质（V 层）和脑干网状结构的纤维。2) 从中脑网状结构到中脑网状结构的生理投射 FFH 以及运动皮层是同侧的，但来自脑桥和延髓的神经元是双侧的。3）这些数据表明，FFH 神经元位于皮质网状连接的交界处，并在维持新皮质系统的癫痫兴奋性中发挥重要作用，正如 Jinnai 和 Mukawa 所建议的那样。
