Individual variability in the posterior hippocampus 2. In this common variant of posterior hippocampal morphology, the ‘ovoid’ portion of the posterior hippocampus separates to become an island in a comparatively anterior portion of the hippocampus when compared with that noted in our protocol. 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’–‘l’) representing a contiguous slice in the posterior direction.
