John Hopton for redOrbit.com - Your Universe Online Testing on rats has shown that too much junk food may teach our brains to disregard the need for a balanced diet. Reduced self-control from eating bad food could chart a course to overeating and obesity that becomes increasingly difficult to deviate from. Research has shown that when rats are given access to a junk food diet, the result is not only weight gain but also a reduced appetite for varied foods. The natural inclination...

FECYT - Spanish Foundation for Science and Technology Abuse could lead to permanent brain damage An international study has analyzed the association between childhood maltreatment and the volume of cerebral grey matter, responsible for processing information. The results revealed a significant deficit in various late developing regions of the brain after abuse. According to the World Health Organisation (WHO), child maltreatment is defined as all forms of physical and/or emotional...

Rats Experience Regret Similar To Humans
2014-06-09 13:11:59

Alan McStravick for redOrbit.com - Your Universe Online In the 2007 Disney feature length Cartoon, Ratatouille, the lead character Remy was separated from his family due to his desire to save Augesten Gusteau's restaurant after reading the famed book "You Can Cook" during the exodus from the besieged farmhouse. That fateful decision and its immediate aftermath were portrayed in such a way that we, as human viewers, were meant to sense Remy's regret. But surely, rats are incapable of such...

MRI Study Shows How The Brain Finds Beauty In Mathematics
2014-02-13 12:39:43

Peter Suciu for redOrbit.com - Your Universe Online To many people math is work, often times hard work. Yet for those who appreciate the beauty of mathematics it can activate the same part of the brain that can appreciate great art or music. To those math lovers an aesthetically pleasing formula is art, and this now suggests that there could be a neurobiological basis to beauty. Thus beauty is truly in the eyes of the beholder, and researchers from University College London, Imperial...

In Europe as well as worldwide, cocaine is the second most frequently used drug after cannabis. Chronic cocaine users display worse memory performance, concentration difficulties, and attentional deficits but also their social skills are affected as previous studies at the Psychiatric Hospital of the University of Zurich suggested. These investigations also revealed that cocaine users have difficulties to take the mental perspective of others, show less emotional empathy, find it more...

How Brain Makes Toss Up Decisions
2013-12-06 13:48:39

Ranjini Raghunath for redOrbit.com - Your Universe Online Some decisions are easy, but when you have two equally appealing choices, how does your brain choose between the two? Scientists have long tried to figure out how toss-up decisions, such as what to eat, drink or watch on TV, are made. A new field of study called neuroeconomics uses theories from economics to try and understand how the brain weighs and picks some options over others. Although scientists have known such...

Anxiety And Social Phobias Made Worse By Missing 'Brake' In The Brain
2013-12-05 05:20:13

redOrbit Staff & Wire Reports - Your Universe Online A team led by researchers from the Medical University of Vienna has discovered one possible source of anxiety disorders and severe phobias – a missing inhibitory connection or “brake” in the brain. When experienced at a manageable level, fear can make people alert and help protect them against danger, it can also disrupt an individual’s sensory perception and reduce happiness when it becomes disproportionate. Now the...

Chronic Dieters Exhibit Brain Imbalance
2013-11-12 09:48:28

Rebekah Eliason for redOrbit.com - Your Universe Online Many people fall prey to the vicious cycle of chronic dieting. Oftentimes willpower waxes and wanes leading to limited dieting success. A new study from Dartmouth using neuroimaging suggests that a brain imbalance may be responsible for overeating in chronic dieters. This imbalance occurs when the region that controls impulse behavior and self-control becomes disrupted, which decreases the ability to resist temptation. This study...

Aurora, CO (PRWEB) August 28, 2013 New research indicates that teens with anorexia nervosa have bigger brains than teens that do not have the eating disorder. That is according to a study by researchers at the University of Colorado’s School of Medicine that examined a group of adolescents with anorexia nervosa and a group without. They found that girls with...

Several human and animal studies have shown a relationship between a preference for highly sweet tastes and alcohol use disorders. Furthermore, the brain mechanisms of sweet-taste responses may share common neural pathways with responses to alcohol and other drugs. A new study using functional magnetic resonance imaging (fMRI) has found that recent drinking is related to the orbitofrontal-region brain response to an intensely sweet stimulus, a brain response that may serve as an important...
