Deep Sleep is Critical For Visual Learning

Remember those "Magic Eye" posters from the 1990s? You let your eyes relax, and out of the tessellating structures, a 3-D image of a dolphin or a yin yang or a shark would emerge.

The research is in PNAS. (full open access)

Ok para pessoas que tiram fotos só para registros.

Para quem tem "olhos de fotografo" seré interessante ter "outros olhos" olhando por ele?

'Ideal biomarker' detects Alzheimer's disease before the onset of symptoms

Absence of prefrontal activation during sensory gating of simple tones predicts Alzheimer's disease (AD) before the occurrence of the first symptoms. Sanja Josef Golubic Ph.D., physicist at the Department of Physics, Faculty of Science, University of Zagreb, reports the high potential of this non-invasive biomarker of AD pathology in a new study published in Human Brain Mapping.

Any Blade Runner fan who doesn’t have mixed feelings about the Blade Runner 2049 sequel probably isn’t much of a fan. Hollywood sequels have a bad track record of course. And while the presence of Harrison Ford might encourage some to hope for a sequel as mighty as Star Wars: The Force Awakens, many of us also (vaguely) remember Indiana Jones and Crystal Skullymajig.

But let’s be crystal clear about one thing. Blade Runner has a strong claim to greatest ever scifi movie ever (with only 2001: A Space Odyssey really in contention for that crown). It also has a good shot at greatest ever movie, no exceptions. Agree with those claims or not, Blade Runner is a profoundly important story, with a place in our cultural life that only a very few works of art will ever reach. The chance to revisit that story is profoundly exciting.

These are my personal questions, going into Blade Runner 2049, that will act as a bellwether of the story’s quality. If the answers to these questions are absent, I suspect the film will be an empty, pretty husk. If they are present, even if the film is not the masterpiece of the original, there will be something there to satisfy me.

New class of molecules may protect brain from stroke, neurodegenerative diseases

Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered a new class of molecules in the brain that synchronize cell-to-cell communication and neuroinflammation/immune activity in response to injury or diseases. Elovanoids (ELVs) are bioactive chemical messengers made from omega-3 very long chain polyunsaturated fatty acids (VLC-PUFAs,n-3). They are released on demand when cells are damaged or stressed. "Although we knew about messengers from omega-3 fatty acids such as neuroprotectin D1 (22 carbons) before, the novelty of the present discovery is that elovanoids are made of 32 to 34 carbon atoms in length," notes Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans. "We expect that these structures will profoundly increase our understanding of cellular cross talk to sustain neuronal circuitry and particularly to restore cell equilibrium after pathological insults." Working in neuronal cell cultures from the cerebral cortex and from the hippocampus and a model of ischemic stroke, the researchers found that elovanoids not only protected neuronal cells and promoted their survival, but helped maintain their integrity and stability. The work is published in Science Advances.
