Facilitates systematic comparison of mouse models of disorders including schizophrenia, autism A new technology developed by neuroscientists at Cold Spring Harbor Laboratory (CSHL) transforms the way highly detailed anatomical images can be made of whole brains. Until now, means of obtaining such images — used in cutting-edge projects to map the mammalian brain -- have been painstakingly slow and available only to a handful of highly specialized research teams. By automating and...

Scientists Find How Our Brains Recognize Faces

A new study by Massachusetts Institute of Technology (MIT) shines new light on how the human brain can recognize faces, as well as how it can discern actual faces from face-like images or objects. According to an MIT press release, our minds are often able to see things that resemble faces, such as the New Hampshire's "Old Man of the Mountain." Yet at the same time, rarely do we have difficulty telling the difference between these and actual faces, and Professor of Brain and Cognitive...

Pioneering vision study in mice will help revolutionize the study of brain function and mental disease There's a 3-D world in our brains. It's a landscape that mimics the outside world, where the objects we see exist as collections of neural circuits and electrical impulses. Now, scientists at the Salk Institute for Biological Studies are using new tools they developed to chart that world, a key step in revolutionizing research into the neurological basis of vision. For the first...

New research reveals a right-hemispheric bias in bats when it comes to tackling navigation and a left-hemispheric advantage for communication Imagine listening to music while carrying on a conversation with friends. This type of multi-tasking is fairly easy to do, right? That's because our brains efficiently and effectively separate the auditory signals — music to the right side; conversation to the left. But what researchers have not been able to do in humans or animals is to see a...

LOS ALAMOS, N.M., Dec. 21, 2011 /PRNewswire-USNewswire/ -- An essential question confronting neuroscientists and computer vision researchers alike is how objects can be identified by simply "looking" at an image. Introspectively, we know that the human brain solves this problem very well. We only have to look at something to know what it is. But teaching a computer to "know" what it's looking at is far harder. In research published this fall in the Public Library of Science...

Smithsonian researchers report that the brains of tiny spiders are so large that they fill their body cavities and overflow into their legs. As part of ongoing research to understand how miniaturization affects brain size and behavior, researchers measured the central nervous systems of nine species of spiders, from rainforest giants to spiders smaller than the head of a pin. As the spiders get smaller, their brains get proportionally bigger, filling up more and more of their body cavities....

Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and isn't always an "inside-out" process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic. The traditional understanding is that the disease begins in the white matter that forms the bulk of the brain's inside, and extends to involve the brain's superficial layers, the cortex. Study findings support an opposite, outside-in...

Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study,...

How the human brain and human cognitive abilities evolved in less than six million years has long puzzled scientists. A new study conducted by scientists in China and Germany, and published December 6 in the online, open-access journal PLoS Biology, now provides a possible explanation by showing that activity levels of genes in the human brain during development changed substantially compared to chimpanzees and macaques. What's more, these changes might be caused by a handful of key...
