A group of people who have "superneurons" have been named. They are not afraid of aging

Biologists who have studied the brains of so-called "SuperAgers" have found a set of enlarged

neurons associated with memory. They also appeared to be more resistant to Alzheimer's disease and represent a unique biological signature.

SuperAgers is a group of people over 80 withexceptional episodic memory at least as good as that of people 20 to 30 years younger. Research into what makes the brains of these super-olds different from the typical brains of older adults has led to exciting discoveries over the past few years. They concern not only memory, but also how they contain neurological degeneration.

PET scans show their brains are differentless accumulation of toxic brain plaques and tangles associated with Alzheimer's disease. And MRI scans have shown that its neural network and connections are more in line with younger people. Other visual memory studies in particular have shown that their brain activity is similar to that of a 25-year-old human.

Based on this, a new study by scientists fromNorthwestern University. Biologists have focused on the entorhinal cortex, the region of the brain responsible for memory. She is one of the first to suffer from Alzheimer's disease. The experts studied six post-mortem brains of "super old people" and found larger and healthier neurons in one of the six layers that make up this area. They were compared with those of seven cognitively average older adults, six younger subjects, and five subjects with early Alzheimer's disease. It turned out that these "superneurons" are much larger.
