Scientists propose new theory on Alzheimer’s, amyloid connection

Posted by in categories: biotech/medical, neuroscience

Worldwide, 50 million people are living with Alzheimer’s disease and other dementias. According to the Alzheimer’s Association, every 65 seconds someone in the United States develops this disease, which causes problems with memory, thinking and behavior.

It has been more than 100 years since Alois Alzheimer, M.D., a German psychiatrist and neuropathologist, first reported the presence of senile plaques in an Alzheimer’s patient brain. It led to the discovery of that produces deposits or plaques of fragments in the brain, the suspected culprit of Alzheimer’s disease. Since then, amyloid has been extensively studied because of its association with Alzheimer’s disease. However, amyloid precursor protein distribution within and on neurons and its function in these cells remain unclear.

A team of neuroscientists led by Florida Atlantic University’s Brain Institute sought to answer a fundamental question in their quest to combat Alzheimer’s disease—” Is amyloid precursor protein the mastermind behind Alzheimer’s disease or is it just an accomplice?”

A woman has regained full consciousness after 28 years in a vegetative state. Munira Abdulla suffered a severe brain injury a car crash in the United Arab Emirates (UAE) in 1991 – when she was 32. “I never gave up on her because I always had a feeling that one day she will wake up,” her son Omar Webair.

Synthetic molecule shows promise as multiple sclerosis treatment

Posted by in categories: biotech/medical, neuroscience

In multiple sclerosis, the body’s immune system attacks and damages myelin, which is the insulating layer on nerves in the spinal cord, brain and optic nerve. This causes the nerves to short-circuit and cease functioning properly. In “a potential game-changer,” scientists have now demonstrated that a synthetic molecule can restore compromised myelin.

The Origins of Us: Evolutionary Emergence and The Omega Point Cosmology — A New Book That Makes You Question The Nature of Reality but Provides You with Surprising Answers | Press Release

Posted by in categories: cosmology, evolution, neuroscience, physics

Ecstadelic Media Group releases a new non-fiction book The Origins of Us: Evolutionary Emergence and The Omega Point Cosmology by Alex M. Vikoulov as a Kindle ebook (Press Release, San Francisco, CA, USA, April 22, 2019 01.00 PM PST)

The Science and Philosophy of Information book series is adapted for general audience and based on the previously published grand volume titled The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution” by digital philosopher Alex Vikoulov on the ultimate nature of reality, consciousness, the physics of time, and philosophy of mind. In this book one of the series, the author addresses some of the most flaming questions in science and philosophy: Where do we come from? What are the origins of us? What is our role in the grand scheme of things?

# 1 Hot New Release” in Amazon charts in Cosmology and Evolution, the book starts with a story that happened almost exactly 400 years ago that has had a tremendous “butterfly” effect on us modern humans.

Scientists Discovered Where Anesthesia Works On the Brain

Posted by in categories: biotech/medical, neuroscience

A medical miracle happened about 170 years ago when scientists discovered general anesthesia that enables millions of patients to undergo invasive, life-saving surgeries without pain. However, in spite of decades of research, scientists cannot understand why general anesthesia works.

In a new study published online in Neuron, scientists believe they have discovered the part of the answer. A team of researchers from a Duke University found that several different general anesthesia drugs knock out the patient by hijacking the neural circuitry that the person falls asleep.

They traced this neural circuitry to a tiny cluster of cells at the base of the brain responsible for churning out hormones to regulate bodily functions, moods, and sleep. The discovery is one of the first to indicate a role for the hormones in maintaining the state of general anesthesia and provides valuable insights for generating newer drugs that could put people to sleep with fewer side effects.

A psychology experiment unexpectedly discovered a man who can’t cooperate because of brain damage

Posted by in category: neuroscience

When someone’s especially cooperative, don’t thank their easy-going nature, but give credit to their brain. A team of New York University psychologists hypothesized that cooperation depends on the dorsolateral prefrontal cortex (DPC), an area of the brain in the frontal lobe involved in regulation control and goal pursuit; after all, cooperation often requires reigning in one’s naughty impulses to take everything for themselves. To test their theory, the researchers conducted an experiment involving participants with brain damage to the DPC—and discovered someone who would not cooperate at all.

For the study, published last year in the journal Social Cognitive and Affective Neuroscience, the researchers recruited 26 healthy control participants alongside 33 participants with brain damage: eight who had frontal-lobe damage, 14 with amygdala damage, and 11 with damage in other areas of the brain. The participants were split into groups of four, and then put through 20 rounds of a decision-making scenario where each person was given $8 and told they could keep it for themselves, or share it equally with the group. After each round, the participants saw whether the others in their group chose to share. Overall, participants cooperated by sharing their money 38.5% of the time.

More interestingly, participants with damage to their DPC were more likely to keep the $8 for themselves. “Overcoming that intuition to be selfish requires them to regulate their response,” says Jay Van Bavel, a professor of psychology at NYU, and one of the study authors. “You just reach and grab for the money whenever you can take it. As people had more damage to their DPC, they were more likely to be selfish.”
