April Flowers for redOrbit.com - Your Universe Online A research team from Inserm has published a new study in the journal Biological Psychology detailing the key role played by a protein, the CB1 cannabinoid receptor, during physical exercise. The team demonstrated, in studies conducted on mice, the location of this receptor - in a part of the brain associated with motivation and reward systems - controls the amount of time for which an individual will carry out voluntary physical...

Dopamine Receptor Gene Variant Linked To Longevity
2013-01-04 10:02:42

Connie K. Ho for redOrbit.com — Your Universe Online A study by brain researchers at the University of California, Irvine (UCI) recently found that a dopamine-receptor gene variant that is related to personality traits can also impact healthy aging. Their findings were published in the January 2 edition of The Journal of Neuroscience. In the paper, the researchers described how the gene variant, known as DRD4 7R allele, is associated with both active personality traits and longer...

The ability of the eye of a fruit fly (Drosophila melanogaster) to respond to light depends on a delicate ballet that keeps the supply of light sensors called rhodopsin constant as photoreceptors turn on and off in response to light exposures, said researchers from Baylor College of Medicine (www.bcm.edu) and the Jan and Dan Duncan Neurological Research Institute (http://www.nri.texaschildrens.org/) at Texas Children's Hospital in an article that appears online in the journal PLOS Biology...

Findings from a new study in Biological Psychiatry A potential new therapeutic strategy for treating Fragile X syndrome is detailed in a new report appearing in the current issue of Biological Psychiatry, from researchers led by Dr. Lucia Ciranna at University of Catania in Italy. Fragile X syndrome (FXS), the most common heritable form of autism and intellectual disability, is one of the most exciting areas in brain research at the moment. A decade ago, Dr. Mark Bear and his...

Odor And The Brain: What The Nose Knows
2012-11-15 11:36:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Specific patterns in the nasal passageway that determine which olfactory neurons are associated with which particular odors have remained a mystery for scientists. The human nose has millions of these olfactory neurons grouped into hundreds of different neuron types. And each of these neuron types expresses only one odorant receptor in one region of the brain, allowing that specific odor to be sensed. Now, researchers from UC...

Brett Smith for redOrbit.com - Your Universe Online As any coffee drinker will tell you, the day immediately begins to feel better after taking that first earthy, faintly bitter sip o´ joe from the edge of a steaming cup. A new study from German researchers reinforces the positive aura swirling around the magical brown elixir as they have shown that caffeine can increase a person´s ability and speed in recognizing words with a positive connotation. The study also shows that...

The Evolution Of Vision
2012-10-30 04:46:51

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Bristol, published in the Proceedings of the National Academy of Sciences (PNAS), sheds light on the origin of sight in animals, including humans. The research team, led by Dr. David Pisani of Bristol's School of Earth Sciences, used computer modeling to provide a detailed picture of how and when opsins evolved. Opsins are conjugated protein enzymes. These enzymes are components of the visual...

On the road at night or on a tennis court at dusk, the eye can be deceived. Vision is not as sharp as in the light of day, and detecting a bicyclist on the road or a careening tennis ball can be tough. New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels. Like the mirror of a telescope...
