Scientists find different brain regions fuel attention
03-29-2007 · Massachusetts Institute of Technology (MIT)If you spotted an anaconda poised to strike, the signal to pay attention would originate in a different part of your brain than if you gazed at an anaconda in the zoo, neuroscientists at MIT's Picower Institute for Learning and Memory report.

- Brain matures a few years late in ADHD, but follows normal pattern
11-12-2007 · EurekAlert!
In youth with attention deficit hyperactivity disorder, the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, MRI scans reveal. The delay in ADHD was most prominent in regions at the front of the brain’s outer mantle important for thinking and attention. Both groups showed a similar back-to-front wave of brain maturation with different areas peaking in thickness at different times.

- Brain's white matter -- More 'talkative' than once thought
05-06-2007 · EurekAlert!
Johns Hopkins scientists have discovered to their surprise that nerves in the mammalian brain’s white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do.

- Brain center for 'sound space' identified
09-19-2007 · EurekAlert!
While the visual regions of the brain have been intensively mapped, many important regions for auditory processing remain terra incognita. Now, researchers have identified the region responsible for a key auditory process -- perceiving "sound space," the location of sounds. The findings settle a controversy in earlier studies that failed to establish the auditory region, called the planum temporale, as responsible for perceiving auditory space.

- Economists help climate scientists to improve global warming forecasts
01-21-2008 · EurekAlert!
Climate scientists are collaborating with experts in economic theory to improve their forecasting models and assess more accurately the impact of rising atmospheric carbon dioxide levels. Although there is broad consensus that there will be a significant rise in average global temperature, there is great uncertainty over the extent of the change, and the implications for different regions.

- UCSF stem cell study reveals cells' capability in mouse brain tissue repair
12-14-2006 · EurekAlert!
UCSF scientists have determined that adult stem cells in a specific region of the mouse brain have a built-in mechanism that allows the cells to participate in the repair and remodeling of damaged tissue in the region.

- Drugs for Parkinson's disease may ease stroke-related disability
04-03-2007 · EurekAlert!
Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease. Researchers at Washington University School of Medicine in St. Louis showed that stroke damage in a brain region known as the putamen is strongly linked to motor neglect, a condition that makes patients slow to move toward the left side.

- Common gene version optimizes thinking -- but with a possible downside
02-08-2007 · EurekAlert!
Most people inherit a version of a gene that optimizes their brain's thinking circuitry, yet also appears to increase risk for schizophrenia, a severe mental illness marked by impaired thinking. The seeming paradox emerged from the first study to explore the effects of variation in the human gene for a brain master switch, DARPP-32. The gene impacts the way two key brain regions exchange information, affecting a range of functions from general intelligence to attention.

- How pain distracts the brain
07-05-2007 · EurekAlert!
Anybody who's tried to concentrate on work while suffering a headache knows that pain compellingly commands attention -- which is how evolution helped ensure survival in a painful world. Now, researchers have pinpointed the brain region responsible for pain's ability to affect cognitive processing. They have found that this pain-related brain region is distinct from the one involved in cognitive processing interference due to a distracting memory task.

- Learning visual prosthesis at the Hanover Fair
04-12-2007 · EurekAlert!
Neural computation scientists at Bonn University have created a software system that is hoped to improve the function of retinal implants significantly: With the aid of the software, the visual prosthesis "learns" to generate exactly those signals, which are expected and can be interpreted by the brain. The learning visual prosthesis will be exhibited between April 16th and April 20th at the community booth of the Science Region Bonn (hall 2, booth D35).

- Strength of connections between brain regions may affect an adolescent's response to peer influence
07-26-2007 · EurekAlert!
Brain regions that regulate different aspects of behavior are more interconnected in children with high resistance to peer influence than those with low resistance, according to a new study published in the July 25 issue of the Journal of Neuroscience.
