Credit: Sharma Lab Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson’s disease through a cellular waste-ejection process, suggests a new study led by Weill Cornell Medicine researchers. During the process, called lysosomal exocytosis, neurons eject protein waste they cannot break down and recycle....
A new study introduces a new neurocomputational model of the human brain that could shed light on how the brain develops complex cognitive abilities and advance neural artificial intelligence research. The study was carried out by an international group of researchers from the Institut Pasteur and Sorbonne Université in Paris, the CHU Sainte-Justine, Mila –...
by Linköping University Credit: Pixabay/CC0 Public Domain Researchers at Linköping University, Sweden, have discovered a biological mechanism that increases the strength with which fear memories are stored in the brain. The study, carried out in rats, is published in Molecular Psychiatry. It provides new knowledge on the mechanisms behind anxiety-related disorders, and identifies shared mechanisms behind...

Credit: Ruy Gómez-Ocádiz, Christoph Schmidt-Hieber, Institut Pasteur The memory system alternates between periods of learning and remembering. These two functions are controlled by different neural circuits. Using an animal model, scientists from the Institut Pasteur recently identified a neural signal in the hippocampus, a brain region...

Credit: Teresa Pais, 2022 A team of researchers from the Instituto Gulbenkian de Ciência (IGC) revealed that cells of the brain can detect the presence of malaria parasites in the blood,...
by Massachusetts General Hospital Credit: Unsplash/CC0 Public Domain Fentanyl is used to supplement sedation and to relieve severe pain during and after surgery, but it’s also one of the deadliest drugs of the opioid epidemic. In research conducted by investigators at Massachusetts General Hospital (MGH) and published in PNAS Nexus, tests of the brain’s electrical activity revealed...
You’re fast asleep. But your brain isn’t taking the night off, according to new research funded by the U.S. National Science Foundation. Researchers studied activity in the human cerebral cortex in response to music and other sounds. They observed vigorous auditory responses in the sleeping brain, similar in many ways to responses in the wakeful state but...
by University of Manchester Credit: Pixabay/CC0 Public Domain A study by University of Manchester neuroscientists into the effect of surprise on our memory has inadvertently discovered a method which might help us to perform better in exams. In the study, published in the Journal of Neuroscience, 26 people were shown pictures of objects that were either...
by Washington University School of Medicine An extended form of the protein aquaporin 4 (red) lines the edges of tiny blood vessels in the brain. Cell nuclei are visible in blue. Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that enhances the amount of long aquaporin 4...
