Physicists studying the brain at Washington University in St. Louis have shown how measuring signals from a single neuron may be as good as capturing information from many neurons at once using big, expensive arrays of electrodes. The new work continues the discussion about how the brain seems to function in a “critical” state. The research was reported in the Journal of Neuroscience.
Marco Colonna, MD, the Robert Rock Belliveau, MD, Professor of Pathology (left), and Timothy J. Ley, MD, the Lewis T. and Rosalind B. Apple Chair in Oncology, both at the School of Medicine, have been elected to the National Academy of Sciences. The new members were announced April 30.
Adult depression has long been associated with shrinkage of the hippocampus, a brain region that plays an important role in memory and response to stress. Now, new research from Washington University in St. Louis has linked participation in team sports to larger hippocampal volumes in children and less depression in boys ages 9 to 11.
A new study from the School of Medicine finds that women’s brains appear to be about three years younger than men’s of the same chronological age, metabolically speaking. The findings could be one clue to why women tend to stay mentally sharp longer than men.
New research led by the School of Medicine suggests that tailoring treatments to men and women with glioblastoma based on the molecular subtypes of their tumors may improve survival for all patients.
Washington University researchers have mapped the regions of the brain in mormyrid fish in extremely high detail. In a study published in the Nov. 15 issue of Current Biology, they report that the part of the brain called the cerebellum is bigger in members of this fish family compared to related fish — and this may be associated with their use of weak electric discharges to locate prey and to communicate with one another.
Four Arts & Sciences faculty members — Megan Daschbach, Janet Duchek, John Shareshian and Lynne Tatlock — were honored during the school’s annual faculty welcome reception, held Sept. 12 in Ridgley Hall’s Holmes Lounge.
An MRI scan often generates an ocean of data, most of which is never used. When overlooked data is analyzed using a new technique developed at the School of Medicine, they surprisingly reveal how many and which brain cells are present – and show where cells have been lost through injury or disease. The findings could lead to new treatments for a variety of brain diseases.
Why don’t you eat your friend’s lunch when you are hungry? Cognitive control. Researchers at the School of Engineering & Applied Science and Arts & Sciences at Washington University in St. Louis are working together to better understand this aspect of cognition.
A new School of Medicine study shows that children born with neurofibromatosis (NF1), a common genetic syndrome, are much more likely to have brain tumors than previously thought.
