Behavioral and morphological identification of the teleost hippocampus using mudskipper.

在本研究中，我们发现弹涂鱼在进行物体识别学习后，表现出cFos免疫反应性的神经元位于背端脑外侧。由于物体识别是空间学习中最重要的能力之一，而且该功能在哺乳动物的海马体和邻近区域进行，因此鱼类背端脑的外侧区域可能与哺乳动物的海马体相当。

In this study, we found that neurons showing cFos immunoreactivity were localized in the lateral part of the dorsal telencephalon in the mudskipper following the object discrimination learning. Since object discrimination is one of the most important abilities for spatial learning and since the function is undertaken in the hippocampus and the adjacent region in mammals, the lateral region of the dorsal telencephalon in fish may be comparable to the mammalian hippocampus.
