the number and health of neurons that survive a heart attack. "We hope that positive social interaction will actually improve the animals' recovery from cardiac arrest," DeVries said. She conducted the study with Gretche...
Binocular rivalry: Fulfilling visual expectations
...g how signaling in the brain allows expectation to influence
visual perception. It is normal to think of vision as beginning with the formation of an image on the back of the eye, which in turn stimulates a cascade of nerve impulses that "feed forward" to send signals deep into the brain. It is in the brain...
Images of 'tail' of protein needed for cell multiplication suggest anticancer drug targets
...e St. Jude researchers report that the stabilizing influence
of Ubc12's protein tail is based on its ability to nestle within a groove of the larger molecule called APPBP1-UBA3. These two proteins, also known by the shorthand designation of E2 (Ubc12) and E1 (APPBP1-UBA3), cooperate with each other to form a w...

behavior, such as learning and memory, a discovery for which the Nobel Prize in Physiology or Medicine was awarded in 2000 to Eric Kandel of Columbia University in New York. Kandel studied how learning behavior was related to serotonergic and other ...
Fossils reveal direct link between global warming and genetic diversity in wildlife

of warming on evolution," she said. "Voles show an influx of new genes and genetic diversity as their population declines, which means they're connected to other populations. But gophers haven't really recovered from the Medieval Warm Period, which e...
