Gut microbes may talk to the brain through cortisol

05/09/2017

Gut microbes have been in the news a lot lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain?

Chronic stress induces fatal organ dysfunctions via a new neural circuit

04/09/2017

New research reveals the mechanisms behind the effects of chronic stress and tiny inflammations in the brain on fatal gut failure. Hokkaido University researchers revealed that fatal gut failure in a multiple sclerosis (MS) mouse model, EAE, under chronic stress is caused by a newly discovered nerve pathway.

Severe stress behind self-perceived memory problems

01/09/2017

Stress, fatigue, and feeling like your memory is failing you. These are the symptoms of a growing group of patients studied as part of a thesis at Sahlgrenska Academy. Result – They may need help, but they are rarely entering the initial stages of dementia.

The brains of newborns distinguish between caresses

25/08/2017

The ability to distinguish between different kinds of caresses on the skin already exists at a very early age. This is evident from a study by the Sahlgrenska Academy, in which the blood supply in brains of infants 6 to 10 weeks old was investigated.

Playing with your brain

16/08/2017

Human-computer interactions, such as playing video games, can have a negative impact on the brain, says a new Canadian study published in Molecular Psychiatry. For over 10 years, scientists have told us that action video game players exhibit better visual attention, motor control abilities and short-term memory. But, could these benefits come at a cost?

Scientists use new data mining strategy to spot those at high Alzheimer's risk

31/07/2017

The push to develop treatments for Alzheimer's disease has been a promising and disappointing endeavor over the past two decades, yielding a greater understanding of the disease yet still failing to generate successful new drugs.

How physical exercise prevents dementia

24/07/2017

Numerous studies have shown that physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age. Now researchers at Goethe University Frankfurt have explored in one of the first studies worldwide how exercise affects brain metabolism.

New gene therapy treatment routes for motor neurone disease uncovered in new study

18/07/2017

Scientists investigating the genetic causes and altered functioning of nerve cells in motor neurone disease (MND) have discovered a new mechanism that could lead to fresh treatment approaches for one of the most common forms of the disease.

A unique amino acid for brain cancer therapy

03/07/2017

Photodynamic therapy is often used to treat brain tumors because of its specificity - it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light.

First-of-its-kind study shows how hand amputation, reattachment affect brain

29/06/2017

When a person loses a hand to amputation, nerves that control sensation and movement are severed, causing dramatic changes in areas of the brain that controlled these functions. As a result, those brain-areas take on other functions. Now, researchers from the University of Missouri have found evidence of specific neurochemical changes associated with lower neuronal health in these brain regions.

Muscle grafts could help amputees sense and control artificial limbs

28/06/2017

A new surgical technique devised by MIT researchers could allow prosthetic limbs to feel much more like natural limbs. Through coordination of the patient’s prosthetic limb, existing nerves, and muscle grafts, amputees would be able to sense where their limbs are in space and to feel how much force is being applied to them.
