The role of brain vasculature in neurodegenerative disorders

Posted by in categories: biotech/medical, neuroscience

Adequate supply of blood and structural and functional integrity of blood vessels are key to normal brain functioning. On the other hand, cerebral blood flow shortfalls and blood–brain barrier dysfunction are early findings in neurodegenerative disorders in humans and animal models. Here we first examine molecular definition of cerebral blood vessels, as well as pathways regulating cerebral blood flow and blood–brain barrier integrity. Then we examine the role of cerebral blood flow and blood–brain barrier in the pathogenesis of Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, and multiple sclerosis. We focus on Alzheimer’s disease as a platform of our analysis because more is known about neurovascular dysfunction in this disease than in other neurodegenerative disorders. Finally, we propose a hypothetical model of Alzheimer’s disease biomarkers to include brain vasculature as a factor contributing to the disease onset and progression, and we suggest a common pathway linking brain vascular contributions to neurodegeneration in multiple neurodegenerative disorders.

Implant helps paralysed man walk again

Posted by in categories: biotech/medical, neuroscience

Five years after he was paralysed in a snowmobile accident, a man in the US has learned to walk again aided by an electrical implant, in a potential breakthrough for spinal injury sufferers.

A team of doctors at the Mayo Clinic in Minnesota say the man, using a front-wheeled walker, was able to cover the equivalent of the length of a football pitch, issuing commands from his brain to transfer weight and maintain balance—all previously thought impossible for .

Known Drug Might Prove Effective Against Alzheimer’s Disease

Posted by in categories: biotech/medical, neuroscience

Apparently, amyloid beta drives its own production in a vicious circle.


In a study at King’s College London, scientists have shown that a vicious circle in which the ill-famed amyloid-beta protein stimulates its own production might be a key factor in the etiology of neurodegeneration in Alzheimer’s disease; furthermore, a drug known as fasudil seems to be effective against amyloid-beta in a mice model of the disease [1].

Scientists discover how to ‘upload knowledge to your brain’

Posted by in category: neuroscience

Feeding knowledge directly into your brain, just like in sci-fi classic The Matrix, could soon take as much effort as falling asleep, scientists believe.

Researchers claim to have developed a simulator which can feed information directly into a person’s brain and teach them new skills in a shorter amount of time, comparing it to “life imitating art”.

They believe it could be the first steps in developing advanced software that will make Matrix-style instant learning a reality.

Postdoctoral Fellow in Neuroscience Research and Integrated Research and Training Fellowship in Neuroscience

Posted by in categories: biotech/medical, neuroscience

Announcing Two Ini Postdoctoral Fellowships

Ini Fellowship in Neuroscience Research

The Iowa Neuroscience Institute ( INI ), part of the Carver College of Medicine at the University of Iowa, seeks talented postdoctoral scientists to engage in cutting-edge neuroscience research. The INI was established in January 2017, supported by a transformational $45 million grant to the University of Iowa from The Roy J. Carver Charitable Trust. Led by Director Ted Abel, Ph.D., the INI is a comprehensive and cross-disciplinary neuroscience center spanning 5 colleges and 26 departments, dedicated to finding the causes of — and preventions, treatments, and cures for — the many diseases that affect the brain and nervous system. Successful candidates will join a strong cohort of postdoctoral fellows working in the field of neuroscience, such as those participating in the NIH –funded INSPIRE program. The University of Iowa Postdoctoral Association provides a variety of social and professional development opportunities on campus.

Marijuana Study Explains How Cannabinoids Help People Experiencing Pain

Posted by in categories: biotech/medical, neuroscience

As of June, a total of 31 states and the District of Columbia allow for the use of medical marijuana. Pain is the most common reason people say they need this cannabis and the vast majority of users say that it helps. However, despite the claims of the many individuals who believe that cannabinoids — the chemicals in marijuana — can ease pain, it’s been difficult for scientists to explain why. Researchers published in JAMA Psychiatry now claim to clarify the discrepancy.

In a systematic review and meta-analysis released Wednesday, scientists from Syracuse University explain that while studies can’t currently prove that cannabinoid drugs reduce pain, research does demonstrate that they can help with the experience of feeling pain. An evaluation of 18 studies that included 442 adults revealed that the use of cannabinoid drugs modestly increased people’s threshold for pain and reduced pain’s overall sensation of unpleasantness. This suggests to the researchers that cannabis’ analgesic properties, or ability to relieve pain, affect the mind rather than the body.

“This [result] is especially salient because managing chronic pain is not solely about minimizing pain,” Kevin Boehnke, Ph.D., who was not involved in the study, tells Inverse. Boehnke is currently a part of a University of Michigan study also analyzing the effect of cannabis on chronic pain. “Sleep problems, fatigue, anxiety, depression, and other factors tie into the experience of chronic pain.”

How Cognitive Computing Can Make You a Better Marketer

Posted by in categories: computing, neuroscience

Since cognitive computing can process massive amounts of data that no human could ever digest and imitate the human brain like no computer system ever has, the technology has amazing potential to amplify our abilities — not replace us — and help us make better, data-driven decisions.

As marketers, we always want to get better. Refining our process and strategy to solve our customers’ problems is our mission. But to understand which tactics actually work and which ones don’t, we usually need to analyze huge sets of complex data.

Data analysis can seem like a tall task, especially if you’re more of a creative marketer. But today, cognitive computing can crunch the numbers for you, helping you make better decisions faster, and hone important aspects of your brand, like brand voice, reporting, and customer support.

Healthy Aging Month: How we can all live better longer

Posted by in categories: biotech/medical, life extension, neuroscience

Buck Institute on the elimination of aging diseases for this and further generations:


September is Healthy Aging Month, and here at the Buck Institute for Research on Aging, we are on a mission to end the threat of age-related disease for this and future generations. We believe it is possible for people to enjoy healthy lives at age 95 as much as they do at 25, and to achieve that, we’re seeking a more comprehensive understanding of the biology of aging itself.

Over the last century, average human lifespan has been increasing at a rate of approximately 2 years per decade, primarily due to advancements in antibiotics and other medical treatments, as well as improved public health efforts. The U.S. Census Bureau estimates that by 2035, people over the age of 65 will outnumber people under 18 for the first time in U.S. history. This means that there is an increasing population of older adults who suffer in the later years of life from chronic diseases including diabetes, neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease, and cancer. While basic scientific research has provided a lot of insight into the causes and potential treatments of individual diseases, the root cause of these and many other chronic diseases is the biological process of aging.
