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

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

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 […]

Diattenuation imaging—a promising imaging technique for brain research

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

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 […]

Team breaks new ground in study of malignant pediatric brain tumor

Scientists are making important progress in the battle against a class of devilishly complex human pediatric brain cancers thanks to a new study from a team of Florida State University students and faculty. Among young children, there’s no brain tumor more common than medulloblastoma. But no specific and effective therapy yet exists for this dangerous disease. Instead, doctors are forced […]

Genetic risk for ADHD manifests in brain structure in childhood

There is only scant scientific evidence available on whether the genetic risk for developing specific psychiatric disorders or cognitive traits is manifest in brain structure from childhood, and to date, studies have focused primarily on adult populations. The question remains unanswered. New evidence has now been provided by a study led by a researcher from the Barcelona Institute for Global […]

Brain condition related to long-term spaceflights needs more attention, data

More people today are poised to explore space than ever before; those who do will experience the effects of microgravity on the human body. Recognizing the need for more data related to those effects, Medical University of South Carolina (MUSC) neuroradiologist Donna Roberts, M.D., and co-author Lonnie G. Petersen, M.D.,Ph.D., University of California San Diego, have published “The Study of […]
