Training and experience can affect brain organization, research shows
11-04-2007 · EurekAlert!New research comparing music conductors and non-musicians shows that both the conductors and the nonmusicians "tuned out" their visual sense while performing a difficult hearing task. As the task became harder, however, only the nonmusicians tuned out more of their visual sense, indicating that the training and experience of the conductors changed how their brains work.

- Experience affects new neuron survival in adult brain; study sheds light on learning, memory
03-22-2007 · EurekAlert!
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults.

- Smell experience during critical period alters brain
12-05-2007 · EurekAlert!
Genes may provide the land, but experience defines the landscape. Now, researchers at Rockefeller University show that during the first few days of life, chronic exposure to carbon dioxide rather than air alters the activity of projection neurons and interneurons in the fly brain -- research that is first to show that the olfactory system is plastic.

- Low levels of neurotransmitter serotonin may perpetuate child abuse across generations
11-02-2006 · EurekAlert!
Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low levels of serotonin are associated with anxiety and depression and impulsive aggression in both humans and monkeys.

- Carnegie Mellon University research shows how sensory-deprived brain compensates
04-17-2007 · EurekAlert!
Whiskers provide a mouse with essential information. These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker. Published April 4 in the Journal of Neuroscience, the results should help shape future studies of sensory deprivation that results from stroke or traumatic brain injury.

- Undergraduate research shows leaderless honeybee organizing
06-11-2007 · EurekAlert!
A new finding by an undergraduate scientist and a senior bee researcher gives new insight on the organization of honeybee colonies, which exhibit behavior rivaling human cultures in social complexity. The study reveals that major colony management activities are directed anonymously by hive workers using a nonspecific signal that modulates worker and queen behavior, and may have implications important for understanding other complex phenomena, from brain activity to terrorist networks.

Researchers from the University of Toronto found that simply thinking about a personal relationship causes sellers to set a higher price, even if the relationship is not directly related to the transaction.

- The 'Freakonomics of Food'
11-22-2006 · EurekAlert!
New research, in "Mindless Eating: Why We Eat More Than We Think," shows that most holiday overeating, is due to the cues around us -- family and friends, packages and plates, shapes and smells, distractions and distances, cupboards and containers. Dubbed the "Freakonomics of Food," the studies in "Mindless Eating" also show how we can reverse these cues to eat less and enjoy it more.
