Dietary fats entering the brain may explain link between obesity and depression

10.05.2019 Health Problems

Obesity and depression have long been linked, with previous clinical studies finding an association between these two conditions. However, until now, the mechanisms of how obesity affects depression and vice versa have not been fully understood. Now, in a new study led by the University of Glasgow in collaboration with the Gladstone Institutes, and published today in Translational Psychiatry, scientists […]

Gender impacts brain activity in alcoholics

30.04.2019 Health Problems

Compared to alcoholic women, alcoholic men have more diminished brain activity in areas responsible for emotional processing (limbic regions including the amygdala and hippocampus), as well as memory and social processing (cortical regions including the superior frontal and supramarginal regions) among other functions. In 2015, the National Survey on Drug Use and Health Alcoholism found 15.1 million adults have Alcohol […]

Somatosensory experiment sheds light on brain function

30.04.2019 Health Problems

After a series of studies, researchers at Lund University in Sweden, together with colleagues in Italy, have shown that not only one part, but most parts of the brain can be involved in processing the signals that arise from touch. The results open the way for a new understanding of how the brain’s network of neurons processes information, and thereby […]

Inhaled hydrogen could protect the brain during heart-lung bypass

30.04.2019 Health Problems

Newborns with life-threatening congenital heart disease often need open-heart surgery with cardiopulmonary bypass, which carries a risk of damaging the brain. Critically ill newborns who are placed on ECMO are at even higher risk for brain injury. Hypothermia, or cooling the body, can improve neurologic outcomes, but has limitations. A new study in a large animal model, published April 29th […]

Scientists restore some functions in a pig’s brain hours after death

17.04.2019 Health Problems

Circulation and cellular activity were restored in a pig’s brain four hours after its death, a finding that challenges long-held assumptions about the timing and irreversible nature of the cessation of some brain functions after death, Yale scientists report April 18 in the journal Nature. The brain of a postmortem pig obtained from a meatpacking plant was isolated and circulated […]

Deep stimulation improves cognitive control by augmenting brain rhythms

04.04.2019 Health Problems

In a new study that could improve the therapeutic efficacy of deep-brain stimulation (DBS) for psychiatric disorders such as depression, a team of scientists shows that, when DBS is applied to a specific brain region, it improves patients’ cognitive control over their behavior by increasing the power of a specific low-frequency brain rhythm in their prefrontal cortex. The findings, published […]

Brain stem cells age faster in multiple sclerosis patients

26.03.2019 Health Problems

Brain stem cells in people with the most severe form of multiple sclerosis look much older than they really are, according to a study led by UConn Health and published in the Proceedings of the National Academy of Sciences (PNAS). The prematurely old cells act differently in the brain than normal ones, and could be the key to new treatments […]

Diattenuation imaging—a promising imaging technique for brain research

20.03.2019 Health Problems

A new imaging method provides structural information about brain tissue that was previously difficult to access. Diattenuation Imaging (DI), developed by scientists at Forschungszentrum Jülich and the University of Groningen, allows researchers to differentiate regions with many thin nerve fibres from regions with few thick nerve fibres. With current imaging methods, these tissue types cannot easily be distinguished. The DI […]

New brain implants disguise as neurons, offering a potentially safer way to study and treat the brain

25.02.2019 Health Problems

Like a well-guarded fortress, the human brain attacks intruders on sight. Foreign objects, including neural probes used to study and treat the brain, do not last long. But now, researchers have designed a probe that looks, acts, and feels so much like a real neuron that the brain cannot identify the imposters. According to Charles M. Lieber, this breakthrough “literally […]

New MRI sensor can image activity deep within the brain

22.02.2019 Health Problems

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain. MIT researchers have now devised a new way to image calcium activity that is based on magnetic resonance […]
