Abstract

An extraordinary development of the paired medullary facial taste nuclei, the facial lobes, occurs in the sea catfish, Plotosus lineatus. Each of the facial lobes is divided by fiber fascicles into 5 highly distinct lobules or subnuclei, constituting 5 longitudinal columns through the lobe. Extracellular, electrophysiological recordings of neurons within the respective subnuclei of the facial lobe indicate superimposable taste and tactile neural maps organized in a somatotopic manner.

摘要

海鲶鱼（Plotosus lineatus）的成对延髓面部味觉核——面神经叶出现了非凡的发育。每个面神经叶被纤维束分成5个高度不同的小叶或亚核，在整个叶中构成5个纵列。对面神经叶各亚核内神经元的细胞外电生理记录表明，味觉和触觉神经图谱以躯体定位的方式叠加排列。
