A technique based on genetic bar codes can easily map the connections of individual brain cells in unprecedented numbers. Unexpected complexity in the visual system is only the first secret it has revealed.

Cryonics pioneer Linda Chamberlain could become a virtually immortal superwoman, but she must choose how: There’s more than one way.

A company called Nectome is developing a technology designed to preserve the brain so the human mind can be uploaded to supercomputers in the future.

A study suggests problems with mental ability and memory with old age are not down to neuron loss, but rather a failure of cells to communicate with each other.

An algorithm tailored to individual brain activity shows it can boost memory with electrical zaps.

Cutting calories by 15% may help protect us against age-related diseases, suggests a new report of a landmark calorie restriction trial with adults. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

The landmark CALERIE study reports that cutting calories by 15 percent slows down an aging metabolism and may help protect against age-related diseases, such as Alzheimer’s, Parkinson’s, type 2 diabetes, cancer and other ailments. The researchers published their results on March 22 in the journal Cell Metabolism.

The researchers found that calorie restriction decreased systemic oxidative stress, one of the nine hallmarks of aging linked to age-related diseases.

How can we help educate the general public?

___ Why you shouldn’t bother with memory or brain health supplements (Consumer Reports): The signs of memory loss can be bewildering and scary: misplaced keys, a forgotten street name, that task you suddenly can’t remember. It’s no wonder that, according to the Nutrition Business Journal, sales of supplements touted.

A new study has confirmed that humankind’s capacity for love and friendship sets us apart from all other species. Researchers at University of Virginia have found that humans are hardwired to empathize with those close to them at a neural level.

Interestingly, the ability to put yourselves in another person’s shoes depends drastically on whether the person is a stranger or someone you know. The study titled “Familiarity Promotes the Blurring of Self and Other in the Neural Representation of Threat” appears in the August issue of the journal Social Cognitive and Affective Neuroscien ce.

According to researchers, the human brain puts strangers in one bin and the people we know in another compartment. People in your social network literally become entwined with your sense of self at a neural level. “With familiarity, other people become part of ourselves,” said James Coan, a psychology professor in University of Virginia’s College of Arts & Sciences who used functional magnetic resonance imaging brain (fMRI) scans to find that people closely correlate people to whom they are attached to themselves.

The first human brain balls—aka cortical spheroids, aka neural organoids—agglomerated into existence just a few short years ago. In the beginning, they were almost comically crude: just stem cells, chemically coerced into proto-neurons and then swirled into blobs in a salty-sweet bath. But still, they were useful for studying some of the most dramatic brain disorders, like the microcephaly caused by the Zika virus.

Then they started growing up. The simple spheres matured into 3D structures, fusing with other types of brain balls and sparking with electricity. The more like real brains they became, the more useful they were for studying complex behaviors and neurological diseases beyond the reach of animal models. And now, in their most human act yet, they’re starting to bleed.

Neural organoids don’t yet, even remotely, resemble adult brains; developmentally, they’re just pushing second trimester tissue organization. But the way Ben Waldau sees it, brain balls might be the best chance his stroke patients have at making a full recovery—and a homegrown blood supply is a big step toward that far-off goal. A blood supply carries oxygen and nutrients, allowing brain balls to grow bigger, complex networks of tissues, those that a doctor could someday use to shore up malfunctioning neurons.
