Best Post of November '09" Finally, a simple cartoon depicting the anatomic location of the transentorhinal cortex

The next in our series of "Best Posts of the Month" is from November 17, 2009: In our teaching and in our autopsy reports, we neuropathologists often make reference to the transentorhinal cortex as it is -- in the Braak and Braak staging system -- the region where the earliest Alzheimer pathology appears. I have found it difficult to find a clear illustration of the anatomic location of the transentorhinal cortex in texts or on the internet. However, I came across a nice cartoon of the divisions of the parahippocampal gyrus, including the transentorhinal cortex, in an online presentation by Prof. Jillian Kril of the Pathology Department at the University of Sydney, NSW . Prof. Kril kindly emailed me a copy of the illustration, which is depicted above with the addition of a label for the presubiculum. Feel free to use this cartoon for teaching purposes with the following credit: Adapted from Harding AJ, Halliday GM, Kril JJ. Variation in hippocampal neuron number with age and brain volume. Cerebral Cortex (December, 1998) 8:710-718.
