A new technique has been developed to control brain activity without the need for invasive surgery or genetic changes. This method uses special nanoparticles to stimulate neurons deep within the brain using near-infrared light. This is a big deal because it allows scientists to study how the brain works in a more precise and less harmful way. The nanoparticles used ...
Brain research often depends on many labs working together to get the same results. But how often do these results match up? This question is especially important when it comes to measuring brain activity in mice during learning tasks. A group of 10 labs decided to find out. They used the same tools and methods to record brain signals in mice as they made decisions. ...
The world of education is buzzing with excitement. Scientists have been diving deep into the brain to understand how we think and feel. This has led to some amazing tools and methods to help students learn better. But here is the twist: even with all these cool advancements, we still don't have a clear picture of how neuroscience, education, and complex thinking all ...
The world of science has seen a significant shift in the way it studies behavior and brain function. One of the key players in this change has been the humble zebrafish. This small, striped fish has become a star in the world of biological research, particularly in the field of behavioral neuroscience. But why has the zebrafish risen to such prominence? And what can ...
The amygdala is a small part of the brain that plays a big role in how people interact with others. Specifically, the basolateral amygdala (BLA) is thought to help figure out how close or distant someone feels to another person. This is important for deciding how generous to be. But does the BLA actually control how kind people are to others? Researchers wanted to fi...
The importance of specialized care for brain injury patients is becoming increasingly clear. A recent study looked at the outcomes of patients with severe brain injuries. These patients had conditions like strokes, bleeding in the brain, or injuries from trauma. The study compared patients treated in dedicated neuroscience intensive care units (NSUs) with thos...
A tiny piece of a mouse’s brain has just given scientists a massive breakthrough in understanding how our brains work. This isn’t just any piece; it’s a speck smaller than a grain of sand from the mouse’s visual cortex. Inside this tiny speck, there are 84, 000 neurons connected by about half a billion synapses. That’s roughly 5. 4 kilometers of neuronal wiring! Thi...
Eye-tracking technology is a hot topic in the worlds of virtual reality, neuroscience, and psychology. It's crucial for making VR experiences more immersive and for helping researchers understand how we process information. However, creating an eye-tracking system that is both accurate and speedy is no easy task. Current methods, like glint tracking, have their limit...
Epilepsy monitoring units (EMUs) are crucial for managing epilepsy patients. These units often require nurses to handle complex evaluations that can increase risks for patients. To address this, the National Association of Epilepsy Centers has set up guidelines for training nurses in advanced epilepsy care. The American Association of Neuroscience Nurses (AANN) step...
In Uruguay, the study of the brain is booming. The Sociedad de Neurociencias del Uruguay is marking 30 years of progress. This progress is fueled by over a century of neuroscience work in the country. This work has used many different methods and creatures to explore the brain. One standout is the fruit fly, Drosophila melanogaster. This tiny fly has been a big deal...
