But there has never been a good explanation for this connection.
“It’s been known for a long time that sleep is really important for brain health,” Lewis says, “but why it is was more mysterious.”
Lewis and a team of researchers wanted to solve the mystery.
By the age of eight, a new study has shown.
Scientists at University College London (UCL) tested the memory and thinking skills of Britons in their late 60s and 70s and compared the results to similar cognitive tests that they took as schoolchildren in 1954.
They found that someone whose cognitive performance was in the top 25 percent as a child, was likely to remain in the top 25 percent at age 70.
After reading the new book “The Case Against Reality: Why evolution hid the truth from our eyes” by cognitive scientist Donald D. Hoffman, many academics and general readers alike may conclude that the Interface Theory of Perception well might be regarded as the most advanced theory of consciousness to date. If you dare to glance outside the paradigmatic square of neuroscience and neurophilosophy, then this book opens up a brand new perspective shedding light on the most probable future venue of scientific endeavor for the theory of everything with computational underpinnings and revolving around phenomenal consciousness.
Challenging the orthodoxy of still-predominant physicalism with undeniable logic and recent epistemological discoveries, Donald Hoffman crafts out his new Interface Theory of Perception which, for some inexplicable reason has been overlooked for so long and is but self-evident: Each conscious agent inhabits their own virtual bubble-universe while using species-specific sensory-cognitive modality in interfacing with objective reality.
In my recently-published book The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution (2019) I go a step further by submitting to you that “that something in objective reality” (in the words of Hoffman) is nothing less than non-local consciousness, or the Universal Mind if you prefer, co-creating each and every observer timeline. My ‘Experiential Realism’ is Hoffman’s Conscious Realism.
Higher serum levels of elaidic acid, an objective biomarker for industrial trans fat, are associated with an increased risk for developing all-cause dementia and Alzheimer disease, according to a study published online Oct. 23 in Neurology.
Takanori Honda, Ph.D., from Kyushu University in Fukuoka, Japan, and colleagues examined the prospective correlation between serum elaidic acid (trans 18:1 n-9) levels and incident dementia in 1,628 Japanese community residents aged 60 years and older without dementia. Participants underwent screening examination in 2002 to 2003 and were followed prospectively to November 2012.
The researchers found that 377 participants developed some type of dementia during follow-up. After adjustment for traditional risk factors, significant correlations were seen for higher serum elaidic acid levels with greater risk for developing all-cause dementia and Alzheimer disease. After adjustment for dietary factors, including total energy intake and intakes of saturated and polyunsaturated fatty acids, these associations remained significant. There was no significant correlation noted for serum elaidic acid levels and vascular dementia.
Here’s something you don’t hear every day: two theories of consciousness are about to face off in the scientific fight of the century.
Backed by top neuroscientist theorists of today, including Christof Koch, head of the formidable Allen Institute for Brain Research in Seattle, Washington, the fight hopes to put two rival ideas of consciousness to the test in a $20 million project. Briefly, volunteers will have their brain activity scanned while performing a series of cleverly-designed tasks targeted to suss out the brain’s physical origin of conscious thought. The first phase was launched this week at the Society for Neuroscience annual conference in Chicago, a brainy extravaganza that draws over 20,000 neuroscientists each year.
Both sides agree to make the fight as fair as possible: they’ll collaborate on the task design, pre-register their predictions on public ledgers, and if the data supports only one idea, the other acknowledges defeat.
The calls started pouring in soon after word spread that Dr. Valerie Taylor was testing fecal microbiota transplantation — transferring poop from one body to another — for bipolar disorder.
The mental health condition is different from depression. It comes with mania, the “up” swings that can make people feel superhuman. “But so many people with depression called wanting to take part in the study we felt we had an obligation to try,” said Taylor, chief of psychiatry at the University of Calgary.
Two years after spearheading the bipolar study, the first of its kind in the world, Taylor has now launched a second study testing fecal transplants in people with depression, as well as a third for depression in people who also have irritable bowel syndrome.
Correlations between pain phenotypes and psychiatric traits such as depression and the personality trait of neuroticism are not fully understood. In this study, we estimated the genetic correlations of eight pain phenotypes (defined by the UK Biobank, n = 151,922–226,683) with depressive symptoms, major depressive disorders and neuroticism using the cross-trait linkage disequilibrium score regression (LDSC) method integrated in the LD Hub. We also used the LDSC software to calculate the genetic correlations among pain phenotypes. All pain phenotypes, except hip pain and knee pain, had significant and positive genetic correlations with depressive symptoms, major depressive disorders and neuroticism. All pain phenotypes were heritable, with pain all over the body showing the highest heritability (h2 = 0.31, standard error = 0.072). Many pain phenotypes had positive and significant genetic correlations with each other indicating shared genetic mechanisms. Our results suggest that pain, neuroticism and depression share partially overlapping genetic risk factors.
Alzheimer’s and diabetes could be connected in ways we’re only beginning to identify, say scientists presenting the latest research on links between blood sugar metabolism and dementia.
