Hormone helps reverse brain damage caused by obesity

06.10.2018 Health Problems

The neurobiotechnology research team of the Universitat Jaume I (UJI) in Castellón, Spain, headed by professor Ana María Sánchez, has proven the positive effects of a vegetable hormone, reversing brain alterations caused by high-fat diets, type-2 diabetes, obesity and physical inactivity. The results of this work, developed by the Health Sciences Department, have been published in Molecular Neurobiology. “We have […]

8-year-old beats the odds against heart and brain birth defects

27.09.2018 Health Problems

The day after Maggie Maine was born, doctors told her parents there was a 70 percent chance she’d never walk, talk or be able to feed or bathe herself. An MRI had found severe defects in both her heart and her brain. Relying on their faith, Jeff and Renae Maine decided to focus on the 30 percent chance that the […]

Scientists unlock secret of how the brain encodes speech

26.09.2018 Health Problems

People like the late Stephen Hawking can think about what they want to say, but are unable to speak because their muscles are paralyzed. In order to communicate, they can use devices that sense a person’s eye or cheek movements to spell out words one letter at a time. However, this process is slow and unnatural. Scientists want to help […]

Nerve cells in the human brain can ‘count’

21.09.2018 Health Problems

How do we know if we’re looking at three apples or four? Researchers at the Universities of Bonn and Tübingen are now one step closer to answering this question. They were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities. A similar effect can be observed […]

Plasticity is enhanced but dysregulated in the aging brain

19.09.2018 Health Problems

They say you can’t teach old dogs new tricks, but new research shows you can teach an old rat new sounds, even if the lesson doesn’t stick very long. Researchers at the Montreal Neurological Institute and Hospital (The Neuro) of McGill University examined the effects of aging on neuroplasticity in the primary auditory cortex, the part of the brain that […]

Brain has natural noise-cancelling circuit

13.09.2018 Health Problems

To ensure that a mouse hears the sounds of an approaching cat better than it hears the sounds its own footsteps make, the mouse’s brain has a built-in noise-cancelling circuit. It’s a direct connection from the motor cortex of the brain to the auditory cortex that says essentially, “we’re running now, pay no attention to the sound of my footsteps.” […]

‘Mindful people’ feel less pain; MRI imaging pinpoints supporting brain activity

07.09.2018 Health Problems

Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found one of the answers—mindfulness. “Mindfulness is related to being aware of the present moment without too much emotional reaction or judgment,” said the study’s lead author, Fadel Zeidan, Ph.D., assistant professor of neurobiology and anatomy at […]

Focused delivery for brain cancers

05.09.2018 Health Problems

A person’s brainstem controls some of the body’s most important functions, including heart beat, respiration, blood pressure and swallowing. Tumor growth in this part of the brain is therefore twice as devastating. Not only can such a growth disrupt vital functions, but operating in this area is so risky, many medical professionals refuse to consider it as an option. New, […]

Effects of deep brain stimulation in patients with Parkinson’s disease

29.08.2018 Health Problems

Researchers at Universitätsmedizin Berlin have studied motor and cognitive effects of deep brain stimulation in patients with Parkinson’s disease. Their results show that the adverse cognitive effects of deep brain stimulation are linked to a different neural pathway than that responsible for the treatment’s desired motor effects. This finding will help optimize treatments for patients with Parkinson’s disease. Results from […]

Traumatic brain injury recovery via petri dish

24.08.2018 Health Problems

Researchers in the University of Georgia’s Regenerative Bioscience Center have succeeded in reproducing the effects of traumatic brain injury and stimulating recovery in neuron cells grown in a petri dish. This makes them the first known scientific team in the country to do so using stem cell-derived neurons. The procedure, detailed in a new paper in Nature Scientific Reports, has […]
