目前有关与海马结构相关的研究，尤其是癫痫的研究，均集中于背侧海马。大量的研究表明背、腹侧海马在功能上存在着显著的差异，尤其在癫痫的急性发作、发作的前驱症状以及癫痫反复发作的形成机制研究中，均证实腹侧海马可能比背侧海马更重要。 Currently, studies related to the hippocampal formation, especially epilepsy, focus on the dorsal hippocampus. A large number of studies have shown that there are significant differences in function between the dorsal and ventral hippocampus, especially in the acute seizures, the prodromal symptoms and the mechanism of recurrent epileptic seizures, confirming that the ventral hippocampus may be more than the dorsal hippocampus important.
