The researchers then used statistical tools to analyze each subject's cursor movements and, therefore, the choice process. They looked at how fast taste began to drive the mouse's movement--and how soon health did. For example, one subject's cursor trajectory might be driven by the taste of the foods very early in the trial, but soon after might be driven by health also--resulting in the selection of the healthier item, like Brussels sprouts over pizza.
Brain
What if you could, for a moment, have the body of someone of a different race, age, or sex? Would that change the way you feel about yourself or the way that you stereotype different social groups? In a paper publishing online December 15 in the Cell Press journal Trends in Cognitive Sciences, researchers explain how they have used the brain's ability to bring together information from different senses to make white people feel that they were inhabiting black bodies and adults feel like they had children's bodies.
DALLAS - Dec. 15, 2014 - UT Southwestern Medical Center researchers have identified a possible therapy to treat neurofibromatosis type 1 or NF1, a childhood neurological disease characterized by learning deficits and autism that is caused by inherited mutations in the gene encoding a protein called neurofibromin.
Researchers initially determined that loss of neurofibromin in mice affects the development of the part of the brain called the cerebellum, which is responsible for balance, speech, memory, and learning.
With the ball at the three-point line near the top of the key, what will Tim Duncan of the NBA's San Antonio Spurs do? Pass to a player posting up? Or does he take a shot? An analysis by Disney Research of player tracking data, however, suggests the highest probability is a pass to guard Tony Parker on his left.
Cold Spring Harbor, NY - The next time you are in a crowded room, or a meeting, or even at the park with your kids, take a look around. How many people are on their phone? Distractions invade every aspect of our lives. Status updates, text messages, email notifications all threaten to steal our attention away from the moment. While we fight the urge to check the phone, our brains are making constant judgment calls about where to focus attention. The brain must continually filter important information from irrelevant interference.
ANN ARBOR, Mich. - Most parents agree their children should be ready to move out of the pediatrician's office into adult-focused care by age 18 - but just 30 percent actually make that transition by that age, according to the University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health.
As health care becomes more complex, it's difficult for teens to shift from relying on their parents to taking on their own health care needs.
Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have discovered a new signal pathway in the brain that plays an important role in learning and the processing of sensory input. It was already known that distinct glial cells receive information from neurons. However, it was unknown that these same glial cells also transmit information to neurons. The glia release a specific protein fragment that influences neuronal cross-talk, most likely by binding to the synaptic contacts that neurons use for communication.
DALLAS - Dec. 15, 2014 - UT Southwestern Medical Center neurology researchers have identified an important cell signaling mechanism that plays an important role in brain cancer and may provide a new therapeutic target.
Researchers found that this mechanism -- a type of signaling termed constitutive or non-canonical epidermal growth factor receptor (EGFR) signaling -- is highly active in glioblastomas, the most common type of adult brain cancer and a devastating disease with a poor prognosis.
Both positive and negative experiences influence how genetic variants affect the brain and thereby behaviour, according to a new study. "Evidence is accumulating to show that the effects of variants of many genes that are common in the population depend on environmental factors. Further, these genetic variants affect each other," explained Sheilagh Hodgins of the University of Montreal and its affiliated Institut Universitaire en Santé Mentale de Montréal.
Perfectionism may be the issue in chronic fatigue and in other medical disturbances such as irritable bowel syndrome and fibromyalgia, according to a new paper.
Immune cells perform a previously unsuspected role in the brain that may contribute to obesity, according to a new study by UC San Francisco researchers.
When the researchers fed mice a diet high in saturated milk fats, microglia, a type of immune cell, underwent a population explosion in the brain region called the hypothalamus, which is responsible for feeding behavior.

Patient awakes from post-traumatic minimally conscious state after administration of depressant drug
Amsterdam, NL, December 12, 2014 - A patient who had suffered a traumatic brain injury unexpectedly recovered full consciousness after the administration of midazolam, a mild depressant drug of the GABA A agonists family. This resulted in the first recorded case of an "awakening" from a minimally-conscious state (MCS) using this therapy. Although similar awakenings have been reported using other drugs, this dramatic result was unanticipated. It is reported in Restorative Neurology and Neuroscience.
In cases of traumatic brain injury (TBI), predicting the likelihood of a cranial lesion and determining the need for head computed tomography (CT) can be aided by measuring markers of bone injury in the blood. The results of a new study comparing the usefulness of two biomarkers released into the blood following a TBI are presented in Journal of Neurotrauma.
WINSTON-SALEM, N.C. - Dec. 12, 2014 - Understanding how nitrite can improve conditions such as hypertension, heart attack and stroke has been the object of worldwide research studies. New research from Wake Forest University has potentially moved the science one step closer to this goal.
