What would you do with a neuron if you could activate its synapses in any combination you wanted? Tiago Branco, Beverley A. Clark and Michael Hauser created a chance to do just that (Branco, 2010). The authors, using in-vitro brain slices containing layer II/III pyramidal cells in visual or somatosensory cortex of rats, were able to excite identified spines in any order and with whatever...

You could have the best hearing aids on the market, but if there is damage to the central auditory system, you're still not going to hear. Comprised of a sophisticated network that includes the auditory cortex and the inferior colliculi, the central auditory system is the part of the brain responsible for processing sound. Scientists at the Instituto de Neurociencias de Castilla y León and...

Scientific research shows that women are twice as likely as men to develop stress disorders. Why are women more sensitive than men to stress? A recent research study presents new evidence that estrogen could play a role. The symptoms of disorders like major depressive disorder and post traumatic stress disorder lead neuroscientists to speculate that a dysfunction occurs in the way the medial prefrontal cortex connects...
Read MoreStomach pain, heartburn, and head rushes are frequent complaints of patients suffering from long-term diabetes. Doctors usually blame these symptoms on autonomic neuropathy, a dysfunction of the nerves that regulate blood pressure, heart rate, and digestion. But there's really not all that much evidence out there to prove this diagnosis. Researchers at the University of Minnesota and Wake Forest University set out to discover the...

When your mouth is dry, your joints are stiff, or your heart is inflamed because your immune system is attacking your own body, chances are you're suffering from a little stress. A recent study shows that there may be physiological reasons why patients with autoimmune diseases experience increased levels of anxiety. Scientists at the City University of New York Medical School, Columbia University, and the University...

Scientists who research genetic disorders might want to reconsider the way they transfer therapeutic genes to cells in the central nervous system. Adeno-associated virus (AAV) vectors are the most common way to transfer DNA into neural cells because of their nonpathogenic nature and long-term transduction abilities. Specifically, researchers most frequently use AAV serotype 2 (AAV2). But scientists at the Yale University School of Medicine believe that...

How do you find the volume of a sphere? It is a question that you’ve answered on math exams stretching all the way back to the sixth grade, but the formula eludes your brain. What is it that causes you to forget something that has been ingrained in your brain Dr. John Morrison of Mount Sinai School of Medicine and Peter R. Rapp, PHD and other...

ScienceDaily (2010-07-21) -- Researchers found that a combination of nutrients called NT-020 promoted adult neural stem cell proliferation in aged rats and boosted their memory and spatial navigation performance. They tested two groups of aged laboratory rats; one group received NT-020 and a control group did not. In the NT-020 treated group, neurogenesis increased and researchers concluded that the NT-020 treated group had fewer activated...
