Abstract

In addition to the corpus callosum and anterior commissure, there are three other fiber systems that link the ventral limbic and paralimbic regions across the hemispheres. In the present study, only Case 13 showed fibers in one of these commissures. This chapter focuses on hippocampal commissures. It theorizes that their role may be related, at least in part, to declarative learning and memory, which have been shown to depend on the integrity of structures in the medial temporal lobe that are linked by these commissures.
