If you are looking for a particular object – say a yellow pencil – on a cluttered desk, how does your brain work to visually locate it? For the first time, a team led by Carnegie Mellon University neuroscientists has identified how different neural regions communicate to determine what to visually pay attention to and what to ignore. This finding is a major discovery for visual cognition and will guide future research into visual and attention deficit disorders. The study,...

Researchers Develop Cerebral Cortex Cells From Skin
2012-02-13 13:44:33

Researchers at the University of Cambridge report that they created cerebral cortex cells from a small sample of human skin. The new development could pave the way for techniques to explore a wide range of diseases such as autism and Alzheimer's. The findings could also enable scientists to study how the human cerebral cortex develops -- and how it "wires up" and how that can go wrong. "This approach gives us the ability to study human brain development and disease in ways that were...

Strategy for maximizing uncertain rewards shows in MRI, math models Life shrouds most choices in mystery. Some people inch toward a comfortable enough spot and stick close to that rewarding status quo. Out to dinner, they order the usual. Others consider their options systematically or randomly. But many choose to grapple with the uncertainty head on. "Explorers" order the special because they aren't sure they'll like it. It's a strategy of maximizing rewards by discovering whether as yet...

Neuroscientists Hyungbae Kwon, PhD and Hiroki Taniguchi, PhD will join Max Planck Florida Institute as research group leaders. MPFI will now have eight research groups, each dedicated to investigating different aspects of the structure and function of neural circuits. Jupiter, Florida (PRWEB) February 04, 2012 The Max Planck Florida Institute (MPFI) announced today that neuroscientists Hyungbae Kwon, PhD and Hiroki Taniguchi, PhD will join the Institute as research group leaders. With the...

Hyperconnectivity triggered by loss of PTEN gene can be blocked by treatment with rapamycin New research from Cold Spring Harbor Laboratory (CSHL) might help explain how a gene mutation found in some autistic individuals leads to difficulties in processing auditory cues and paying spatial attention to sound. The study has found that when a suspected autism gene called PTEN is deleted from auditory cortical neurons–the main workhorses of the brain's sound-processing...

Brain circuits for visual categorization revealed by new experiments Hundreds of times during a baseball game, the home plate umpire must instantaneously categorize a fast-moving pitch as a ball or a strike. In new research from the University of Chicago, scientists have pinpointed an area in the brain where these kinds of visual categories are encoded. While monkeys played a computer game in which they had to quickly determine the category of a moving visual stimulus, neural recordings...

The incredible ability of our brain to create a three-dimensional (3D) representation from an object's two-dimensional projection on the retina is something that we may take for granted, but the process is not well understood and is likely to be highly complex. Now, new research published by Cell Press in the January 12 issue of the journal Neuron provides the first direct evidence that specific brain areas underlie perception of different 3D structures and sheds light the way that the...

Scientists model brain structure to help computers recognize objects 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...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
