The
entorhinal cortex, shown below in red, is the layer of grey matter
tissue on a specific subregion of the parahippocampal gyrus of the
temporal lobe.
Our
tracing method measures the bilateral entorhinal cortex volumes
using standard T2 images and atlas-based boundaries. Our results
suggest that the entorhinal cortex volume has greater variability
(see graph below) than the hippocampal body volume and therefore
is not as powerful for detecting dementia as the hippocampus.
