Brains have now been imaged at a map-like or “meso” scale, using the most powerful X-ray beams in the country, a team of researchers led by Eva Dyer, a computational neuroscientist and electrical engineer, reports. The imaging scale gives an overview of the intercellular landscape of the brain at a level relevant to small neural… Read more

One oral dose of methylene blue results in an increased MRI-based response in brain areas that control short-term memory and attention, according to a new study. Methylene blue, also known as methylthioninium chloride, is used to treat methemoglobinemia, a blood disorder in which oxygen is unable to release effectively to body tissues, and as a… Read more

Imaging patients soon after traumatic brain injury (TBI) occurs can lead to more accurate detection of cerebral microhemorrhages, or microbleeding on the brain, according to a study of military service members. Cerebral microhemorrhages occur as a direct result of TBI and can lead to severe secondary injuries such as brain swelling or stroke. The ability… Read more

Women in early stages of breast cancer may benefit more from shorter, yet more intensive radiation treatment, a recent study has found. The women have less toxicity and higher quality of life in comparison to those who undergo a longer course of treatment, according to researchers from The University of Texas MD Anderson Cancer Center… Read more
