Sleep and aging: Two sides of one coin?

Sleep and aging: Two sides of one coin?

A link has been identified between oxidative stress, which has previously been linked to aging and neurodegeneration, and sleep. Oxidative stress activates neurons that control sleep function. The findings could help in the development of treatments for sleep disorders.

Artificial Intelligence Can Predict Premature Death

Artificial Intelligence Can Predict Premature Death

Machine learning significantly improves the accuracy of predicting premature deaths, from all causes, in a middle-aged population compared with more traditional models.

They found this AI system was very accurate in its predictions and performed better than the current standard approach to prediction developed by human experts. The study is published by PLOS ONE in a special collections edition of “Machine Learning in Health and Biomedicine”.

The team used health data from just over half a million people aged between 40 and 69 recruited to the UK Biobank between 2006 and 2010 and followed up until 2016.

So, is everyone already on #Minds?

So, is everyone already on #Minds?

I'm still with little over 200 followers there, a very small percentage from here. I've started my account there end of last year, so far it has been a great experience, very similar to #Google+.

#MeWe is more like #Facebook, didn't like it much for sharing #science and #technology news.

I can have access to most news that interest me ( #robotics #artificialintelligence #technology #science #health #eco etc) directly from my feed on Minds, you just need to follow the right people ;).

Check it out, let's keep in touch!

The Sleeping Brain Remains Attentive to Its Environment

The Sleeping Brain Remains Attentive to Its Environment

Researchers report our brain can track the sounds in its environment while we sleep, and favor the most relevant ones. This aptitude could be one of the mechanisms that allow us to sleep in complete safety and wake up at the right moment.

Epigenetics Contributes to Male and Female Differences in Fear Memories

A new mouse study reveals males recall fearful memories better than females. Researchers attribute the difference to the gene Cdk5, which has previously been implicated in creating fear memories and stress behaviors.

"Neuroscience has drifted off a little bit from the directions that Freud was going in terms of the interpretations of whether your unconscious mind is sending you particular hidden signals and so on. But the idea that there's this massive amount happening under the hood, that part was correct and so Freud really nailed that. And he lived before the blossoming of modern neuroscience, so he was able to do this just by outside observation and looking at how people acted.
Nowadays, we're able to peer noninvasively inside people's heads as they're doing tasks, as they're thinking about things and making decisions, perceiving the world. We're able to go a lot deeper into understanding this massive machinery under the hood."

*Paper proposes new way to understand how the neocortex works
by Numenta*

Scientists at Numenta propose a major new theory about how the human brain works. While neuroscientists have amassed an enormous amount of detailed factual knowledge about the brain, there remains no unifying theory as to what intelligence is and how the brain produces it. In their paper, "A Framework for Intelligence and Cortical Function Based on Grid Cells in the Neocortex," Numenta researchers describe a broad framework for understanding what the neocortex does and how it works. The paper appears in the journal Frontiers in Neural Circuits. The key insight described in the paper relates to a type of neuron called grid cells. Grid cells exist in an older part of the brain that learns maps of environments. As you move, grid cells keep track of the location of your body relative to these maps. Numenta researchers deduced that grid cells also must exist throughout the neocortex. These "cortical grid cells" track the locations of your sensors as they move relative to the objects in the world. The authors propose that cortical grid cells allow the neocortex to learn models of objects similar to how the older part of the brain learns maps of environments. The paper proposes how we learn the structure and behavior of objects based on locations and location spaces defined by cortical grid cells.
