TBI laws effective at reducing rate of recurrent concussions, new study shows

Thu, 19 Oct 2017 16:42:53 EDT

A recent study from the Center for Injury Research and Policy at Nationwide Children's Hospital done in conjunction with researchers from Colorado School of Public Health at the University at Colorado and Temple University used data from a large, national sports injury surveillance system to determine the effect of state-level TBI laws on trends of new and recurrent concussions among US high school athletes.

HIV infection, even with antiretroviral therapy, appears to damage a growing child's brain

Tue, 17 Oct 2017 11:01:18 EDT

One of the largest and best-documented trials of children receiving early antiretroviral therapy -- the CHER clinical trial in South Africa -- finds ongoing white matter damage in HIV-positive children at the age of 7 years. The study aims to contribute to a better understanding of brain development in HIV-infected and exposed children, as well as the impact of long-term antiretroviral treatment.

Zinc-binding is vital for regulating pH levels in the brain

Tue, 17 Oct 2017 09:22:42 EDT

Researchers in Oslo, Norway, have discovered that Zinc-binding plays an important role in the sensing and regulation of pH in the human brain. The findings come as one of the first studies that directly link Zinc-binding with bicarbonate transporters.

Our brain omits grammatical elements when it has limited resources

Wed, 11 Oct 2017 12:03:53 EDT

A study of the use of pronouns by French speakers with agrammatic aphasia shows that grammatical pronouns are significantly more impaired in speech than lexical ones. The findings support a new theory of grammar which suggests that grammatical elements contain secondary information that speakers with limited cognitive resources can omit from their speech and still make sense.

Better mini brains could help scientists identify treatments for Zika-related brain damage

Tue, 10 Oct 2017 20:01:37 EDT

Researchers have developed an improved technique for creating simplified human brain tissue from stem cells. Because these so-called 'mini brain organoids' mimic human brains in how they grow and develop, they're vital to studying complex neurological diseases.

When the brain's wiring breaks

Tue, 10 Oct 2017 14:32:45 EDT

Among all the bad things that can happen to the brain when it is severely jolted - in a car accident, for example - one of the most common and worrisome is axon damage. Axons are the long stalks that grow out of the bodies of neurons. When the brain receives a strong blow, axons can break or swiftly degenerate. Researchers have revealed new molecular details of this and a path toward repair.

Alzheimer's gene poses both risk and benefits

Mon, 09 Oct 2017 15:48:05 EDT

Scientists studying the molecular roots of Alzheimer's disease have encountered a good news/bad news scenario. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system's ability to protect the brain from amyloid beta. The good news, according to researchers, is that later in the disease, the absence of TREM2 protein seems to protect the brain from damage.

Study pokes holes in fetal alcohol hypothesis

Wed, 04 Oct 2017 12:23:03 EDT

A new study appears to challenge the theory that cells in the brain's immune system are the culprit behind the neurological damage that occurs in children exposed to alcohol while in the womb.

Neuroscientists find 'gatekeeper' in itching sensations plays no role in pain transmission

Tue, 03 Oct 2017 12:51:14 EDT

A neurotransmitter study in mice found that BNP is involved in relaying itching sensations but not pain. A better understanding of pain and itch pathways could help researchers develop targeted therapies for diseases with chronic itching, including multiple sclerosis and kidney failure.

New insights into how sleep helps the brain to reorganize itself

Mon, 02 Oct 2017 08:56:52 EDT

A study has given new insights into how sleep contributes to brain plasticity -- the ability for our brain to change and reorganise itself -- and could pave the way for new ways to help people with learning and memory disorders.
