Insulin sensitizer also serves as energy-conserving signal to the brain
07-10-2007 · EurekAlert!A fat-derived protein known for its effects on the liver and skeletal muscle might also serve as an energy-conserving signal to the brain during periods of starvation, suggests a new study in the July issue of Cell Metabolism, a publication of Cell Press. The substance, known as adiponectin, acts on the brain to boost appetite and slow energy expenditure in an effort to maintain adequate fat stores during lean times, the researchers report.

- Brain wave changes in adolescence signal reorganization of the brain
12-06-2006 · EurekAlert!
Brain wave changes in adolescence are related to age, but not sexual maturation, occur earlier in girls than boys and may be associated with one of the brain's major reorganization projects: synaptic pruning, a new study finds. During adolescence, the brain reorganizes and eliminates many synaptic connections, making the brain's information processing more efficient and powerful while consuming less energy.

- Revealing estrogen's secret role in obesity
08-20-2007 · EurekAlert!
Research on the effects of the female sex hormone estrogen in the brain lend credence to what many women have suspected about the hormonal changes that accompany aging: Menopause can make you fat. In animal experiments, researchers showed how estrogen receptors in the brain serve as a master switch to control food intake, energy expenditure and body fat distribution. The study will be presented in August at the American Chemical Society national meeting in Boston.

- Left brain helps hear through the noise
11-14-2007 · EurekAlert!
Our brain is very good at picking up speech even in a noisy room, an adaptation essential for holding a conversation at a cocktail party, and now we are beginning to understand the neural interactions that underlie this ability. An international research team reports today, in the online open-access journal BMC Biology, how investigations using neuroimaging have revealed that the brain's left hemisphere helps discern the signal from the noise.

- Depiction of findings selected as '2007 Image of the Year' by Society for Nuclear Medicine
06-04-2007 · EurekAlert!
An image depicting research findings linking brain chemistry with aggressive personality has been named "2007 Image of the Year" by the Society for Nuclear Medicine. The research, which was performed at the U.S. Department of Energy's Brookhaven National Laboratory, showed that healthy men with lower levels of a particular brain enzyme exhibited more aggressive personality traits, as measured by a standard personality questionnaire.

- Experimental weight-loss drug cuts appetite, burns more energy
01-08-2008 · EurekAlert!
The first clinical studies of an experimental drug have revealed that obese people who take it for 12 weeks lose weight, even at very low doses. Short-term studies also suggest that the drug, called taranabant -- the second drug designed to fight obesity by blocking cannabinoid receptors in the brain -- causes people to consume fewer calories and burn more energy.

- Neuron cell stickiness may hold key to evolution of the human brain
11-02-2006 · EurekAlert!
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees and other vertebrates, researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules.

- Discovery supports theory of Alzheimer's disease as form of diabetes
09-26-2007 · EurekAlert!
Insulin may be as important for the mind as it is for the body. Recent research has raised the possibility that Alzheimer's memory loss could be due to a novel third form of diabetes. Scientists at Northwestern University have discovered why brain insulin signaling would stop working in Alzheimer's disease. They have shown that a toxic protein found in the brains of individuals with Alzheimer's removes insulin receptors from nerve cells, rendering those neurons insulin-resistant.

- Researchers develop marker that identifies energy-producing centers in nerve cells
02-01-2007 · EurekAlert!
A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. This fluorescent marker protein may shed light on brain cell defects believed to play a role in various neurological diseases.

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.
