Adaptation in reaching - gradual improvement of motor control in response to a perturbation - is a central issue in motor neuroscience.However, even the cortical origin of errors that drive adaptation has remained elusive. In a new paper Inoue, Uchimura and Kitazawa have shown that error signals encoded by motor cortical neurons drive adaptation in reaching.
In a startling discovery that raises fundamental questions about human behavior, researchers at the University of Virginia School of Medicine have determined that the immune system directly affects – and even controls – creatures’ social behavior, such as their desire to interact with others. So could immune system problems contribute to an inability to have normal social interactions? The…
The age of exploration has long passed, but there is at least one area still largely uncharted: the human brain. Now, a detailed new map by researchers at Washington University School of Medicine in St. Louis lays out the landscape of the cerebral cortex – the outermost layer of the brain and the dominant structure involved in sensory perception and attention, as well as distinctly human…
A European study led by Umeå University Professor Lars Nyberg, has shown that the dopamine D2 receptor is linked to the long-term episodic memory, which function often reduces with age and due to dementia. This new insight can contribute to the understanding of why some but not others are affected by memory impairment.
A new nano-fabricated platform for observing brain cancer cells provides a much more detailed look at how the cells migrate and a more accurate post-surgery prognosis for brain cancer (glioblastoma) patients.
First the good news: the most severe Ebola outbreak ever has been contained. Last December, Guinea, where the first infection was reported in late 2013, was declared free of Ebola cases. Liberia was considered free of Ebola in mid-January after no new case had been reported for 42 days (the WHO criterion for ‘free of Ebola’).
Cooperation on Artificial Intelligence complements its initiatives on Enterprise Imaging, Big Data and Clinical Analytics, to provide an e-Health platform for Integrated Care and Population Health Management.
CarThera, a French company based at the Brain and Spine Institute (ICM), that designs and develops innovative ultrasound-based medical devices to treat brain disorders, announces the publication on initial successes in disrupting the blood-brain barrier (BBB) with the use of ultrasound. This has been achieved in association with teams from the Assistance Publique-Hôpitaux de Paris (the Greater…
Her Majesty Queen Elizabeth II has officially opened the Cardiff University Brain Research Imaging Centre (CUBRIC), a unique neuroimaging research hub in Wales. The facility will seek to provide unprecedented insights into the causes of neurological and psychiatric conditions such as dementia, schizophrenia and multiple sclerosis, as well as an understanding into the mechanisms of a healthy…
Scientists at the University of British Columbia and Vancouver Coastal Health have proven that multiple sclerosis (MS) can be caused by a single genetic mutation – a rare alteration in DNA that makes it very likely a person will develop the more devastating form of the neurological disease.
The Zika epidemic has long assumed global proportions, experts told the Congress of the European Academy of Neurology in Copenhagen. Europe needs to get prepared to deal with the relentless spread of the health threat, in particular with a view to “imported” infection. Awareness for prevention and personal protection is important, in particular with thousands of athletes and fans soon…
Scientists from the universities in Münster and Munich have discovered what precisely goes wrong in the body in the case of multiple sclerosis (MS). At the same time the neuroscientists were able to demonstrate that for MS, which occurs in bouts, there is a therapy which is tailor-made to eliminate the deficit.
New EU-funded project CoSTREAM targets the common mechanisms and pathways of stroke, Alzheimer’s disease to improve disease prevention and treatment, by combining clinical, genetic, epidemiologic, metabolic and radiologic research to develop an organ-on-a-chip in vitro model for the blood-brain connection that will revolutionise drug-development.
Researchers from Germany and the USA have identified an important mechanism with which memory switches from recall to memorization mode. The study may shed new light on the cellular causes of dementia. The work was directed by the University of Bonn and the German Center for Neurodegenerative Diseases (DZNE).
A multicenter research team led by Columbia University Medical Center (CUMC) has discovered a new neurodevelopmental syndrome and the genetic mutations that cause it. The discovery is an important step toward creating targeted therapies for individuals with this syndrome, which causes severe developmental delays, abnormal muscle tone, seizures, and eye complications.
Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its outer layer, the cortex.
Georgetown University researchers are reporting the first case of Alzheimer’s disease diagnosed in an HIV-positive individual. The finding in a 71-year-old man triggers a realization about HIV survivors now reaching the age when Alzheimer’s risk begins to escalate.
Since the recent link to severe neurological defects in infants born to mothers infected during pregnancy, Zika virus (ZIKV) has become a public health and research priority. A study reports details from the 2015 Zika outbreak in Rio de Janeiro - the first with a high proportion of cases confirmed by molecular diagnosis - and proposes changes to the current diagnostic criteria for ZIKV disease.
The Zika virus may be associated with an autoimmune disorder that attacks the brain's myelin similar to multiple sclerosis, according to a small study that is being released today and will be presented at the American Academy of Neurology's 68th Annual Meeting in Vancouver, Canada, April 15 to 21, 2016.
For epilepsy patients and attending physicians, it has been a challenge to correctly assess the frequency and severity of epileptic seizures without inpatient recording equipment. A consortium coordinated by the epileptologists of the University Hospital Bonn is now developing a mobile sensor that can detect seizures. A warning signal is designed to summon relatives or attending physicians to…
A team of researchers at the MedUni Vienna has, in collaboration with the AIT Austrian Institute of Technology, developed two new PET tracers that allow the activity of drug transporters at the blood-brain barrier to be measured. The studywas able to demonstrate that people with a genetic polymorphism in a transporter gene have lower transporter activity at the blood-brain barrier, which can lead…
The odor of bobcat urine, if you ever get a chance to take a whiff, is unforgettable — like rotten meat combined with sweat, with something indescribably feral underlying it. To humans, it’s just nose-wrinklingly disgusting. But to mice, it smells like one thing: fear.
A research team headed by scientists at the Institute of Neuroimmunology and the Institute for Multiple Sclerosis Research (IMSF), University Medical Center Göttingen (UMG), has gained new insights into the immune function of cerebrospinal fluid (CSF). They used real-time microscopy to film the lively trafficking of immune cells between the CSF and the nervous tissue. Here the meninges play the…
Siemens Healthcare has launched a range of new MR applications to help hospitals reduce the time needed for MR imaging within neurology. It is estimated that 20 to 25 per cent of all MR examinations are neurological, with the number expected to grow in 2016 (1). The applications have therefore been designed to help organisations increase patient throughput in order to maintain an efficient…
According to the American Heart Association, ischemic strokes account for nearly 90 percent of all strokes. They occur when a blocked artery prevents blood from getting to the brain and usually result in long-term disability or death. Now, a team of researchers led by the University of Missouri School of Medicine has developed a new, real-time method of imaging molecular events after strokes - a…
