Neurons (IMAGE) Simons Foundation Caption Principal neurons of the entorhinal cortex layer II assist with memory and navigation and are among the most vulnerable to Alzheimer's. Researchers generated a line of mice for studying ECII neurons (highlighted using a green fluorescent protein). The neurons are at such high risk because they frequently remodel, making them prone to fatal dysfunctions, the researchers found. Credit J.-P.
