Reaching and grasping: Learning fine motor coordination changes the brain

Reaching for and grasping objects brings about changes in the connections of a certain neuronal population in the red nucleus, a region of the midbrain, now reported by researchers at the University of Basel’s Biozentrum. They have also shown how fine motor tasks promote plastic reorganization of this brain region. The results of the study have been published in Nature […]

Brain supplements: Four of the best supplements for optimal brain health

The brain requires a constant supply of oxygen and glucose, which is carried to the brain by the blood. Like the rest of the body, the brain depends on food to run at peak performance hence the reason we feel our brains are the sharpest after a good meal. Eating a varied diet that includes fresh, unprocessed foods in a […]

Broccoli sprout extracts may help manage schizophrenia

Drugs used to treat schizophrenia don't work completely for everyone, and they can cause a variety of undesirable side effects, including metabolic problems increasing cardiovascular risk, involuntary movements, restlessness, stiffness and "the shakes." A chemical derived from broccoli sprouts can be used to manage schizophrenia symptoms, scientists have found, paving the way for treatments that reduces unwanted side effects of […]

Train your brain to eat less sugar

More than half of American adults consume excess added sugars, according to the U.S. Department of Health and Human Services. Major dietary guidelines recommend limiting foods high in added sugars. A recent study led by Evan Forman, Ph.D., a psychology professor in Drexel University’s College of Arts and Sciences, shows that a computer game can be used to train its […]

Detailed brain map uncovers hidden immune cells that may be involved in neurodegenerative disorders

Brains contain a variety of immune cells that play an important role for brain function. A team led by Prof. Kiavash Movahedi (VIB Center for Inflammation Research at VUB) has developed a comprehensive cell atlas of the brain’s immune compartment. This revealed not only the striking diversity of brain macrophages, but also uncovered microglia where they were not expected. Remarkably, […]

Study shows that artificial neural networks can be used to drive brain activity

MIT neuroscientists have performed the most rigorous testing yet of computational models that mimic the brain’s visual cortex. Using their current best model of the brain’s visual neural network, the researchers designed a new way to precisely control individual neurons and populations of neurons in the middle of that network. In an animal study, the team then showed that the […]

How live recordings of neural electricity could revolutionize how we see the brain

Red and blue lights flash. A machine whirs like a distant swarm of bees. In a cubicle-sized room, Yoav Adam, a microscope, and a video projector capture something no one has ever seen before: neurons flashing in real time, in a walking, living creature. For decades scientists have been searching for a way to watch a live broadcast of the […]

Same brain cells active during sleep and exploration in mice

Researchers have mapped the activity of individual neurons deep in the brain during sleep and exploration of novel objects in male and female mice. The study, published in JNeurosci, suggests these cells may facilitate memory formation. Melanin-concentrating hormone (MCH) neurons are active during rapid-eye movement (REM) sleep, when dreaming—and perhaps memory consolidation—occurs. Carlos Blanco, Priyattam Shiromani, and colleagues at the […]

Pig experiment raises ethical questions around brain damage

The brain is more resilient than previously thought. In a groundbreaking experiment published in this week’s issue of Nature, neuroscientists created an artificial circulation system that successfully restored some functions and structures in donated pig brains—up to four hours after the pigs were butchered at a USDA food processing facility. Though there was no evidence of restored consciousness, brains from […]
