be sure to discuss the difference between the ec label thats included in the aparc atlas versus this new ec label. Please note that there two entorhinal labels exist in FreeSurfer 1) the EC label included in the aparc atlas and the cytoarchitecturally-defined entorhinal label (i.e., the ex vivo one).

or if you have freesurfer, run this to map from surface space to volume space and then this is how you view it.

Entorhinal Cortex

flateconlyinflated2014.jpg

The entorhinal cortex is located on the crown of the anterior parahippocampal gyrus. Brodmann assigned the number 28 to entorhinal cortex (Brodmann’s area 28). Entorhinal cortex displays a unique cytoarchitecture with large neurons in layer II that form clusters. The entorhinal cortex is the gateway to the hippocampus. In Alzheimer’s disease (AD), neurons in the entorhinal cortex, particularly those in layer II, begin to die and some leave behind a pathological marker – the neurofibrillary tangle. Neurofibrillary tangles and significant cell death characterize the neuronal loss in AD where neurofibrillary tangles and subsequent atrophy have been correlated with dementia.

Please note that there two entorhinal labels exist in FreeSurfer 1) the EC label included in the aparc atlas and the cytoarchitecturally-defined entorhinal label (i.e., the ex vivo one).
