Individual variability in the posterior hippocampus 1. In this common variant of posterior hippocampal morphology, the ‘ovoid’ portion of the posterior hippocampus noted in the protocol does not emerge. Rather, the dorsal and ventral portions of the hippocampus close on each other, making delineation of these regions difficult. Here, we offer an example of how we segment in the context of this particular morphological characteristic. ‘a’ represents the anterior-most slice, with each subsequent panel (‘b’–‘p’) representing a contiguous slice in the posterior direction.
