An ultra-small, wireless, battery-free device uses light to record individual neurons so neuroscientists can see how the brain is working, researchers report. “As biomedical engineers, we are working with collaborators in neuroscience to improve tools to better understand the brain, specifically how these individual neurons, the building blocks of the brain, interact with each other… Read more

Imagine that you are driving to work along an icy road when a deer suddenly jumps into your path. Depending on the distance, you may have time to apply the brakes, or you may consider swerving to avoid a collision. Your intuitive ability to reason about the physics of objects in your environment, for instance… Read more

Mice quickly learn a fearful response to a situation perceived as threatening, but for such a conditioned response to become long-lasting requires brain cells to increase amounts of an insulating material called myelin, which may serve to reinforce and stabilize newly formed neural connections, scientists at UC San Francisco report. “We find that a single… Read more

A causal mechanism of how novel stimuli promote learning has been identified by brain scientists from KU Leuven and the Flanders Institute for Biotechnology. The findings have implications for improving learning strategies and for the design of machine learning algorithms. “Previous work suggested that novelty might activate the dopamine system in the brain. Therefore we… Read more

In mammalian adult brains, neural stem cells are only present in few specific regions, so-called niches. Only these niches are capable of generating new neurons. For the first time, researchers have defined the proteome of these niches, the entire set of expressed proteins, and compared it to other regions of the brain. The findings[1] help… Read more
