To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor. The complex and diverse olfactory system they build remains adaptable, but a new study in the journal Science shows that the system's flexibility, or plasticity, has its limits. Working in mice, Brown University scientists found that the fundamental neural wiring map between the nose and the brain becomes established in a critical period of early development and then...

Memory Area Of Brain In Older Women Boosted With Regular Aerobic Exercise
2014-04-11 08:42:55

BMJ-British Medical Journal Twice weekly routine may help to slow down advance of dementia, say researchers Regular aerobic exercise seems to boost the size of the area of the brain (hippocampus) involved in verbal memory and learning among women whose intellectual capacity has been affected by age, indicates a small study published online in the British Journal of Sports Medicine. The hippocampus has become a focus of interest in dementia research because it is the area of the brain...

Brain disconnect leaves teen brain less able to judge trustworthiness Making a snap decision usually means following your initial reaction -- going with your gut. That intuitive feeling sprouts from the limbic system, the evolutionarily older and simpler part of the brain that affects emotion, behavior and motivation. But during adolescence, the limbic system connects and communicates with the rest of the brain differently than it does during adulthood, leaving many adolescents...

Max Planck Institute for Chemical Ecology Odorant receptors of recent insects evolved long after insects migrated from water to land. An insect’s sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at the Max Planck Institute for Chemical Ecology, many proteins involved in the highly sensitive odor perception of insects emerged...

redOrbit Staff & Wire Reports - Your Universe Online For decades, experts have claimed that people were capable of detecting 10,000 different odors, but new research appearing in the March 21 edition of Science suggests that the actual number of scents detectable by the human nose is considerably higher. In fact, according to an experiment led by Andreas Keller of the Rockefeller University Laboratory of Neurogenetics and Behavior, human noses and brains are sensitive enough to...

WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/ -- A new research project, entitled Spotlight on Senior Health: Adverse Health Outcomes of Food Insecure Older Americans, finds that food insecure seniors are more likely than those who are food secure to have lower nutrient intake and to be at a higher risk for chronic health conditions and depression. The study --released jointly by Feeding America and the National Foundation to End Senior Hunger (NFESH)--reveals that food insecurity is...

Emotion Detectors May Make Driving Safer

[ Watch The Video: Emotion Detection ] Ecole Polytechnique Fédérale de Lausanne EPFL scientists are studying how to identify drivers' emotions using embedded cameras that film their faces Technology now allows us to read facial expressions and identify which of the seven universal emotions a person is feeling: fear, anger, joy, sadness, disgust, surprise, or suspicion. This is very useful in video game development, medicine, marketing, and, perhaps less obviously, in driver...

Hippocampus Stores Memories By Temporal Context
2014-03-14 09:49:22

[ Watch the Video: Recollection of Times Past: How the Brain Stores Memories ] UC Davis Before I left the house this morning, I let the cat out and started the dishwasher. Or was that yesterday? Very often, our memories must distinguish not just what happened and where, but when an event occurred — and what came before and after. New research from the University of California, Davis, Center for Neuroscience shows that a part of the brain called the hippocampus stores memories by their...

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...
