The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a pervasive 3D grid structure with no diagonals, say scientists funded by the National Institutes of Health. Included in this […]

For decades, scientists have dreamed of building computer systems that could replicate the human brain’s talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain’s neurons adapt in response to new information. This phenomenon, known as plasticity, is believed […]
Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons – a dance of chemical messages so delicate that missteps often lead to neurological dysfunction.
In an effort to unravel the tangled biology of autism, Johns Hopkins scientists have created a mouse model that mimics a human mutation of a gene known to be associated with autism spectrum disorders. Experiments with the engineered mouse reveal a molecular mechanism by which mutations of the gene named Shank3 affect the brain and […]
A University of Wisconsin-Madison research team has solved a 25-year mystery that may lead to better treatments for people with learning deficits and mental retardation. Synaptophysin is the first protein and most abundant ever found on the membranes surrounding the tiny sacs that carry chemical messengers to synapses, the gaps where communication between nerve cells […]
A team of Neuroscientists from NeuroCure Cluster of Excellence at Charité – Universitätsmedizin Berlin and Baylor College of Medicine in Houston, Texas, have made a major breakthrough in understanding how signals are processed in the human brain. The paper, published in the current issue of the scientific journal Neuron, shows that a certain type of […]
You may remember the color of your loved one’s eyes for years. But how? Scientists believe that long-term potentiation (LTP) – the long-lasting increase of signals across a connection between brain cells – underlies our ability to remember over time and to learn, but how that happens is a central question in neuroscience.
New research on the genomics of autism confirms that the genetic roots of the disorder are highly complicated, but that common biological themes underlie this complexity. In the current study, researchers have implicated several new candidate genes and genomic variants as contributors to autism, and conclude that many more remain to be discovered. While the […]
