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

鲶鱼等夜行性鱼类的摄食行为不仅受味觉的调节，还受其他感官的调节。这项研究揭示了内器官、中枢通路、大脑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，人们发现海鲶鱼（Plotosus japonicus）可以检测到pH值从环境水平瞬时下降~0.05-0.10个单位，这使它们能够检测到海洋蠕虫（多毛虫），这是由于蠕虫的呼吸活动。对海鲶鱼神经节中面部味觉循环神经元的形态和组织结构进行了研究，结果表明，尽管躯干分支和胸鳍分支在体位上分别位于面叶的前外侧和中间内侧区域，但在神经节中没有明显的地形关系。

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.
