It appears that over 80s who are still mind-intelligent have significantly larger than average neurons

We are (on average) getting older, and more and more people are living to 80 or older. In this very old category, you also have people whose brains seem to be forever fit SuperRagers.

Aging goes hand in hand with slow decline in memory function, just as we slowly but surely deteriorate physically. But SuperAgers continue to have an excellent memory, and they can perfectly compete with people under the age of 20-30.

study which is Published in the Journal of Neuroscience, in the case of neurons in the entorhinal cortex or entorhinal cortex (ERC), an area of ​​our brain important for memory and at the same time vulnerable to degeneration. Researchers at Northwestern University were able to examine the brains of SuperAgers who had donated their bodies to science after their death. In the study, they compared 24 brains, including 6 from SuperAgers. The latter lived to an average age of 91 years. Other brains came from “normal” peers, young adults, or peers who had deteriorated cognitively.
