Once we fully we understand intelligence it could be essentially increased to nearly infinite levels once everything is quantified like this article talks about 😗😁.

Modern humans have a gene mutation that boosts the growth of neurons in the brain neocortex, a brain region associated with higher intelligence.

The recreation of the human brain is giving clues to essentially how we engineer a super brain someday 😀.

Nobody’s quite sure what it means yet. But we’re sure that it’s important.

This is leading to even better brain engineering 👏 🙌 👌 😀 😄.

Computer-augmented brains, cures to blindness, and rebuilding the brain after injury all sound like science fiction. Today, these disruptive technologies aren’t just for Netflix, “Terminator,” and comic book fodder — in recent years, these advances are closer to reality than some might realize, and they have the ability to revolutionize neurological care.

Neurologic disease is now the world’s leading cause of disability, and upwards of 11 million people have some form of permanent neurological problem from traumatic brain injuries and stroke. For example, if a traumatic brain injury has damaged the motor cortex — the region of the brain involved in voluntary movements — patients could become paralyzed, without hope of regaining full function. Or some stroke patients can suffer from aphasia, the inability to speak or understand language, due to damage to the brain regions that control speech and language comprehension.

Could changing your diet play a role in slowing or even preventing the development of dementia? We’re one step closer to finding out, thanks to a new UNLV study that bolsters the long-suspected link between gut health and Alzheimer’s disease.

The analysis — led by a team of researchers with the Nevada Institute of Personalized Medicine (NIPM) at UNLV and published this spring in the Nature journal Scientific Reports — examined data from dozens of past studies into the belly-brain connection. The results? There’s a strong link between particular kinds of gut bacteria and Alzheimer’s disease.

UNLV study pinpoints 10 bacterial groups associated with Alzheimer’s disease, provides new insights into the relationship between gut makeup and dementia.

The study’s authors compared the influence of two components of the brain’s physical structure: the outer folds of the cerebral cortex — the area where most higher-level brain activity occurs — and the connectome, the web of nerves that links distinct regions of the cerebral cortex. The team found that the shape of the outer surface was a better predictor of brainwave data than was the connectome, contrary to the paradigm that the connectome has the dominant role in driving brain activity. “We use concepts from physics and engineering to study how anatomy determines function,” says study co-author James Pang, a physicist at Monash University in Melbourne, Australia.

A model of the brain’s geometry better explains neuronal activity than a model based on the ‘connectome’.

Opting for olive oil could reduce your risk of fatal dementia, according to a new study.

Participants who included half a tablespoon of olive oil in their daily diet were 28% less likely to die of dementia.

The study authors found that replacing a single teaspoon of margarine or mayonnaise with olive oil reduced the risk of fatal dementia by 8–14%.

Mothers who eat apples and herbs in early pregnancy could be protecting the brain health of their children and grandchildren, a Monash University study using genetic models has found.

The discovery is part of a project that found a mother’s diet can affect not just her child’s brain but also those of her grandchildren.

Published in Nature CellBiology, the Monash Biomedicine Discovery Institute study found that certain foods could help protect against the deterioration of brain function.

Low-grade inflammation contributes to age-related decline and impairment, but the precise pathways responsible for this inflammation and their impact on natural aging have until now remained elusive.

A study headed by researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) has now shown that a molecular signaling pathway known as cGAS/STING plays a critical role in driving chronic inflammation and functional decline during aging. Andrea Ablasser, PhD, and colleagues found that blocking the STING protein suppressed inflammatory responses in human senescent cells and tissues, and reduced aging-related inflammation in multiple peripheral organs and in the brain in mice.

The researchers in addition studied the effects of blocking the STING protein in aged mice. As expected by its central role in driving inflammation, inhibiting STING alleviated markers of inflammation both in the periphery and in the brain. “Notably, various aging-related immune signature genes were significantly attenuated as a result of STING inhibition,” they stated. And importantly, animals receiving STING inhibitors displayed significant enhancements in spatial and associative memory, as well as improved muscle strength and physical endurance.

New research on mice has shed light on how high blood pressure causes changes to arteries in the brain, a process that leads to vascular dementia. The research, led by University of Manchester scientists, funded by the British Heart Foundation and published today in the journal Proceedings of the National Academy of Sciences, ^[1] has uncovered a route to developing the first ever drug treatments for vascular dementia that directly target a cause of the condition.

High blood pressure is the main cause of vascular dementia, a condition characterised by poor blood flow to the brain. The reduced blood supply starves brain cells of nutrients and over time they become damaged and die. Symptoms of vascular dementia include loss of energy, lack of concentration and poor memory.

It’s normal for the brain’s arteries to narrow and widen in response to changes in blood pressure. However, consistently high blood pressure causes arteries to stay narrow and restrict the brain’s blood supply. Until now, it was not known why.
