Decoded neurofeedback to help instill confidence, reduce fear

A new technique of analyzing brain patterns appears to help people overcome fear and build self-confidence. The approach, developed by a UCLA-led team of neuroscientists, is described in two new papers, published in the journals Nature Communications and Nature Human Behaviour. Study subjects were conditioned to fear certain color patterns, but researchers found that small …

Increased brain connectivity seen in endurance runners.

University of Arizona researchers discovered that MRI scans of endurance runners’ brains have greater functional connectivity than the brains of more sedentary individuals. Researchers compared brain scans of young adult cross country runners to young adults who don’t engage in regular physical activity. The runners, overall, showed greater functional connectivity or connections between distinct brain …

Deep brain magnetic stimulation provides precise and reliable activation of target neurons

Massachusetts General Hospital (MGH) researchers have developed what appears to be a significant improvement in the technology behind brain implants used to activate neural circuits responsible for vision, hearing or movement. The investigators, who are also affiliated with the Boston VA Healthcare System, describe their development of tiny magnetic coils capable of selectively activating target …

Research categorizes depression in to 4 subtypes based on fMRI scans

Patients with depression can be categorized into four unique subtypes defined by distinct patterns of abnormal connectivity in the brain, according to new research from Weill Cornell Medicine. In a collaborative study published in Nature Medicine, Dr. Conor Liston, an assistant professor of neuroscience in the Feil Family Brain and Mind Institute and an assistant …

Magnetoencephalography and computational analysis to accurately diagnose concussions

Simon Fraser University researchers have found that high-resolution brain scans, coupled with computational analysis, could play a critical role in helping to detect concussions that conventional scans might miss. In a study published in PLOS Computational Biology, Vasily Vakorin and Sam Doesburg show how magnetoencephalography (MEG), which maps interactions between regions of the brain, could …

New biomarker based on expression of SHOX2 gene for predicting survival in Gliomas

Researchers at UT Southwestern Medical Center have found a new biomarker for glioma, a common type of brain cancer, that can help doctors determine how aggressive a cancer is and that could eventually help determine the best course of treatment. The findings are published in EBiomedicine. Researchers from the Harold C. Simmons Comprehensive Cancer Center found …

NeuroVascular Unit on a chip created to mimic functions of Blood-brain barrier

The blood-brain barrier is a network of specialized cells that surrounds the arteries and veins within the brain. It forms a unique gateway that both provides brain cells with the nutrients they require and protects them from potentially harmful compounds. This is an illustration of the neurovascular unit on a chip.Credit: Dominic Doyle, Vanderbilt University An …

Role of Hippocampus in future thinking and scene construction

Over the past decade, researchers have learned that the hippocampus historically known for its role in forming memories is involved in much more than just remembering the past; it plays an important role in imagining events in the future. Yet, scientists still do not know precisely how the hippocampus contributes to episodic imagining until now. …

Research shows new understanding on how working memory is stored in brain

Working memory is integral part of  cognitive process and it involves short term memory. Previous research shown that  it depends on sustained, elevated brain activity. However researchers at University of Wisconsin-Madison have shown that humans can hold information in working memory via “activity-silent” synaptic mechanisms. Their study is published in journal Science. According to Brad Postle, …
