In time, this knowledge can lead to new treatments for a number of conditions. The study, a collaboration between KU Leuven, Massachusetts...

The prognosis for BLBC-BM patients is poor, as the blood-brain...
by University of Kent Credit: Unsplash/CC0 Public Domain Research from the University of Kent has led to the development of the MeshCODE theory, a revolutionary new theory for understanding brain and memory function. This discovery may be the beginning of a new understanding of brain function and in treating brain diseases such as Alzheimer’s. In a...

The lesions are outlined in green.

There are a few ways we perceive food, and not all are particularly well-understood. We know that much of it happens in the olfactory bulb, a small lump of tissue between the eyes and behind the nose, but how the stimuli arrive at this part of the brain is still being worked out. How these...
by Max Planck Society Neural variability may provide a unique window into brain function. Credit: NomeVisualizzato & Cassidy Dickens, CC0 The brain’s neural activity is irregular, changing from one moment to the next. To date, this apparent “noise” has been thought to be due to random natural variations or measurement error. However, researchers at the Max Planck Institute...
Professor Kimitaka Nakazawa, a specialist in neurorehabilitation, first had the opportunity to study the brain activity of a Paralympic gold medalist in January 2016, when he visited a university pool in the United States as part of an NHK television program called “Chojin-tachi no Paralympic” [The superhuman Paralympians]. He was struck by what he could...
By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more. Olena Shmahalo/Quanta Magazine; noise generated by Thomas Donoghue Elizabeth Landau February 8, 2021 At a sleep research symposium in January 2020, Janna Lendner presented findings that hint at a way to look at people’s brain activity for signs of...
by Giorgia Guglielmi, Ecole Polytechnique Federale de Lausanne Credit: CC0 Public Domain EPFL researchers have identified specific neurons that help activate sensory processing in nearby nerve cells—a finding that could explain how the brain integrates signals necessary for tactile perception and learning. The ability to perceive touch sensations gives our brains a wealth of information about the environment,...
