by University of California – San Diego Newly developed brain maps with unprecedented detail are helping answer critical questions about brain blood flow. These new maps offer resolution finer than a millionth of a meter, reconstructed here with high microvessel density areas in red, intermediate density areas in white and low density areas in blue.

People have searched for sex differences in human brains since at least the 19th century, when scientist Samuel George Morton poured seeds and lead shot into human skulls to measure their volumes. Gustave Le Bon found men’s brains are usually larger than women’s, which prompted Alexander Bains and George Romanes to argue this size difference...
by University of Technology, Sydney A study published in Current Biology reports on one of the first comprehensive characterizations of poorly formed memories, and may offer a framework to explore different therapeutic approaches to fear, memory and anxiety disorders. It may also have implications for accuracy of some witness testimony. Senior author Professor Bryce Vissel,...

Credit: Ingvild Festervoll Melien A study performed by researchers from the University of Bergen, Norway, and the University of Vienna, Austria, shows damage of the mitochondria—the cell’s microscopic powerhouses—in the brains of people with Creutzfeldt-Jacob disease. The researchers found that the mitochondrial power generator (known as...
It’s Brain Awareness Week, and to mark the occasion, we’re taking a look at research focused on the most complex organ in the human body. You can view all of our content for Brain Awareness Week here. Anecdotally, love is a matter of the heart. However, the main organ affected by love is actually the...
By SHARON BEGLEY @sxbegleDECEMBER 10, 2019 Even allowing for the fact that these were lilliputian brains, they were not behaving at all according to plan. From the first days of the tiny lab-grown organs’ development, primitive “progenitor cells” romped out of their birthplaces in the deep interior and quickly turned into neurons and glia, specialized...
A study led by Massachusetts General Hospital (MGH) investigators has identified a critical role for a protein called Kruppel-like factor 9 (Klf9) in the brain’s response to stress, which has implications for protecting against the effects of stress in conditions like major depression and post-traumatic stress disorder (PTSD). In their paper published in Cell Reports, the...
