We each live in a unique odor world According to Gertrude Stein, "A rose is a rose is a rose," but new research indicates that might not be the case when it comes to the rose's scent. Researchers from the Monell Center and collaborating institutions have found that as much as 30 percent of the large array of human olfactory receptor differs between any two individuals. This substantial variation is in turn reflected by variability in how each person perceives odors. Humans have about...

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...

Smell Processes In Our Brain Better Understood Through Locust Study
2013-11-26 09:53:56

April Flowers for redOrbit.com - Your Universe Online Environmental stimuli often trigger our sense of smell before we exhibit any other response. Smells trigger neurons in our brains that alert us to take action, but there are often more than one odor in our environments at any given time. Barani Raman, PhD, of the School of Engineering & Applied Science at Washington University in St. Louis, wanted to answer the question of how our brain processes multiple odors received...

Navigation Abilities Brain Structure

Brett Smith for redOrbit.com - Your Universe Online People who instantly know their way around after having traveled to a particular destination at least once have structurally different brains than those who require a map or GPS to navigate from place to place, new research shows. Doctoral researcher Joost Wegman at Radboud University Nijmegen in the Netherlands demonstrated that good navigators store relevant landmarks automatically along the way to their destination, while bad...

A team of researchers at Inserm led by Cyril Herry (Inserm Unit 862, “Neurocentre Magendie,” Bordeaux) has just shown that interneurons located in the forebrain at the level of the prefrontal cortex are heavily involved in the control of fear responses. Using an approach combining in vivo recordings and optogenetic manipulations in mice, the researchers succeeded in showing that the inhibition of parvalbumin-expressing prefrontal interneurons triggers a chain reaction resulting in fear...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
