Genes May Not Be to Blame for Link Between Migraine and Heart Disease

A new study suggests that genes may not be to blame for the increased risk of heart disease some studies have shown in people with migraine, especially those with migraine with aura. The research is published during Headache/Migraine Awareness Month in the inaugural issue of the journal Neurology® Genetics, an open access, or free to the public, online-only, peer-reviewed journal from the American Academy of Neurology. Aura are sensations that come before the headache, often visual disturbances such as flashing lights.

Long-Term Memories Are Maintained by Prion-Like Proteins

Research from Eric Kandel’s lab has uncovered further evidence of a system in the brain that persistently maintains memories for long periods of time.

Water to Understand the Brain

By using intrinsic optical signals (IOS) imaging, researchers from the University of Geneva (UNIGE), Switzerland, demonstrated that, contrary to what was thought, another physiological variation is involved: the activated neurons swell due to the massive entry of water. This discovery provides evidence that a much finer analysis of the functioning of the brain - and of its dysfunctions - is possible.

New Light Switches for Neurons Advance Brain Research

ApprovedphotoforSciencenewsrelease.jpg

Light switches for neurons have made enormous contributions to brain research by giving investigators access to “on switches” for brain cells. But, finding “off switches” has been much more challenging. Addressing the challenge, biochemists in the Center for Membrane Biology at The University of Texas Health Science Center at Houston (UTHealth) discovered a new family of light-activated proteins that work as “off switches.”

Human Brain Study Sheds Light on How New Memories are Formed

Pisa1.jpg

In the first study of its kind, UCLA and United Kingdom researchers found that neurons in a specific brain region play a key role in rapidly forming memories about every day events, a finding that may result in a better understanding of memory loss and new methods to fight it in Alzheimer’s and other neurological diseases.
