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. |
