Critical viewing – The maturation of inhibitory synapses in the visual cortex is modulated by visual experience

. Sensory experience changes the way humans see the world during early postnatal development. Now, an international team of researchers, including Tadaharu Tsumoto from the RIKEN Brain Science Institute in Wako, may have an explanation. They report in the journal Neuron that visual experience drives the maturation of inhibitory synapses in the visual cortex during …

Neural Stem Cells Attack Glioblastoma Cells

. In their latest research, scientists of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have demonstrated how the brain’s own stem cells and precursor cells control the growth of glioblastomas. Of all brain tumors, glioblastomas are among the most common and most aggressive. Dr. Sridhar Reddy Chirasani, Professor Helmut Kettenmann and Dr. …

Decoding monkey movements – recording neuronal activity

. Producing accurate and stable, long-term readings of neuronal activity using a brain–machine interface (BMI) is now possible thanks to work by Naotaka Fujii and his colleagues at the RIKEN Brain Science Institute, Wako1. Their results could help researchers to develop durable and versatile neural prostheses for rehabilitation patients. . BMIs read neural activity associated …

Proper maturation of the visual cortex in mice, and possibly humans, depends on a maternal gene

. החלק היותר גדול של מוחנו, מוקדש לעיבוד של אותות הראייה. עכשיו מתברר שגן מסוים, שאותו אנו יורשים מאימותינו בלבד, הוא האחראי להתפתחות התקינה של האיזור הזה במוח. אמא יש רק אחת, והיא קובעת את הדרך שבה אנו רואים את העולם.. The copy of the gene Ube3a inherited from the mother—not the father—is crucial to …
