Studies on the neural mechanism for releasing the feeding behavior of fish

叉尾鱼等夜间活动鱼类的摄食行为不仅受味觉的影响，还受其他感官的影响。这项研究揭示了大脑的内脏、中央通路、初级中枢和大脑中嗅觉、侧线、内耳和内脏感官的高级通路。在味觉方面，研究发现，由于海洋蠕虫(多毛类)的呼吸活动，海豚能从周围环境水平检测到约0.05-0.10个pH单位的瞬时下降，从而能够检测到海洋蠕虫(多毛类)。本文研究了面神经递归神经元的形态及其在神经节内的组织结构。结果表明，尽管躯干和胸鳍支分别位于面叶的前外侧区和中间内侧区，但在神经节内没有明显的解剖关系。

Feeding behavior of nocturnal fish such as catfish is mediatedby not only taste but also other senses. This studies revealed endorgans, central pathways, primary center of the brain and higher pathways in the brain for the olfactory, lateral line and inner ear and visceral senses. For the taste sense, the sea catfish, Plotosus japonicus, was found to detect transient drops of ~0.05-0.10 pH unit from ambient levels that enable them to detect marine worms (polychaets), due to the worm’s respiratory activities. The morphology of the recurrent facial taste neurons and their organization in the ganglion of the sea catfish were studies and the results show that no distinct topographical relationship of the trunk and pectoral-fin branches occurs in the ganglion although the two branches somatotopically in the anterolateral and intermediate medial regions of the facial lobe, respectively.
