Using direct human brain recordings, a research team from Drexel University, the University of Pennsylvania, UCLA and Thomas Jefferson University has identified a new type of cell in the brain that helps people to keep track of their relative location while navigating an unfamiliar environment. The "grid cell," which derives its name from the triangular grid pattern in which the cell activates during navigation, is distinct among brain cells because its activation represents multiple...

SF-based Two Degrees Food and DC-based Earth Starter have created a partnership to donate meals to children in need for every Nourishmat garden purchased. San Francisco, CA (PRWEB) July 24, 2013 Two Degrees, Inc., the first buy-one give-one food company, and Earth Starter, a food empowerment company that teaches consumers how to grow their own food, have teamed up to provide meals to hungry kids across America. The partnership brings together two food-focused, social startups with a...

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...

In the constant cross talk between our brain and our gut, two gut hormones are already known to tell the brain when we have had enough to eat. New research suggests that boosting levels of these hormones simultaneously may be an effective new weapon in the fight against obesity. Dr Shu Lin, Dr Yan-Chuan Shi and Professor Herbert Herzog, from Sydney’s Garvan Institute of Medical Research, have shown that when mice are injected with PYY3-36 and PP, they eat less, gain less...

Fish fail to detect danger in copper-polluted water. A new study, to be presented at the meeting of the Society for Experimental Biology on the 5th of July, shows that fish cannot smell a danger odor signal emitted by other fish in waters contaminated with copper. Research conducted by Dr Bill Dew at the University of Lethbridge in Canada looked for the first time at the effect of the metal contaminants nickel and copper on specific fish olfactory sensory neurons, and how these affect the...

Brain Handles Stress Better When Bodies Are Exercised

April Flowers for redOrbit.com - Your Universe Online A new study led by Princeton University reveals physical activity reorganizes the brain so that its response to stress is decreased. This makes anxiety less likely to interfere with normal brain function. The findings, published in The Journal of Neuroscience, show when regularly exercised mice experienced a stressor -- for example, exposure to cold water -- their brains exhibited a spike in the activity of neurons that shut off...

You might be falling in love with that new car, but you probably wouldn't pay as much for it if you could resist the feeling. Researchers at Duke University who study how the brain values things -- a field called neuroeconomics -- have found that your feelings about something and the value you put on it are calculated similarly in a specific area of the brain. The region is small area right between the eyes at the front of the brain. It's called the ventromedial prefrontal cortex, or...

A key brain structure that regulates emotions works differently in preschoolers with depression compared with their healthy peers, according to new research at Washington University School of Medicine in St. Louis. The differences, measured using functional magnetic resonance imaging (fMRI), provide the earliest evidence yet of changes in brain function in young children with depression. The researchers say the findings could lead to ways to identify and treat depressed children earlier in...

Anyone who's ever heard a Beethoven sonata or a Beatles song knows how powerfully sound can affect our emotions. But it can work the other way as well – our emotions can actually affect how we hear and process sound. When certain types of sounds become associated in our brains with strong emotions, hearing similar sounds can evoke those same feelings, even far removed from their original context. It's a phenomenon commonly seen in combat veterans suffering from...

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
