Scientists Identify Genetic Risk for Major Depression A new study reveals a novel gene associated with major depression. The research, published in the April 28 issue of the journal Neuron, suggests a previously unrecognized mechanism for major depression and may guide future therapeutic strategies for this debilitating mood disorder. Major depression is a psychiatric disorder [...]
Microsleep: Brain Regions Can Take Short Naps During Wakefulness, Leading to Errors If you’ve ever lost your keys or stuck the milk in the cupboard and the cereal in the refrigerator, you may have been the victim of a tired brain region that was taking a quick nap. Researchers at the University of Wisconsin-Madison have [...]
Brain Nerve Stimulation Could Speed Up Learning In a breakthrough that may aid treatment of learning impairments, strokes, tinnitus and chronic pain, UT Dallas researchers have found that brain nerve stimulation accelerates learning in laboratory tests. Another major finding of the study, published in the April 14 issue of Neuron, involves the positive changes detected [...]
Mechanism of Long-Term Memory Identified Using advanced imaging technology, scientists from the Florida campus of The Scripps Research Institute have identified a change in chemical influx into a specific set of neurons in the common fruit fly that is fundamental to long-term memory. The study was published in the April 13, 2011 issue of The [...]
Computer Model of the Brain Scientists have moved a step closer to being able to develop a computer model of the brain after developing a technique to map both the connections and functions of nerve cells in the brain together for the first time. A new area of research is emerging in the neuroscience known [...]
Bullying Alters Brain Chemistry in Mice Being low mouse on the totem pole is tough on murine self-esteem. It turns out it has measurable effects on brain chemistry, too, according to recent experiments at Rockefeller University. Researchers found that mice that were bullied persistently by dominant males grew unusually nervous around new company, and that [...]
Scientists Find New Type of Mineral in Historic Meteorite NASA and co-researchers from the United States, South Korea and Japan have found a new mineral named “Wassonite” in one of the most historically significant meteorites recovered in Antarctica in December 1969. The new mineral was discovered within the meteorite officially designated Yamato 691 enstatite chondrite. [...]
Chimp, Bonobo Study Sheds Light on the Social Brain It’s been a puzzle why our two closest living primate relatives, chimpanzees and bonobos, have widely different social traits, despite belonging to the same genus. Now, a comparative analysis of their brains shows neuroanatomical differences that may be responsible for these behaviors, from the aggression more [...]
Yellow Lab Dye Profoundly Extends Lifespan in Healthy Nematodes Basic Yellow 1, a dye used in neuroscience laboratories around the world to detect damaged protein in Alzheimer’s disease, is a wonder drug for nematode worms. In a study appearing in Nature, the dye, also known as Thioflavin T (ThT), extended lifespan in healthy nematode worms [...]
Cancer Turns out to Be a P53 Protein Aggregation Disease Protein aggregation, generally associated with Alzheimer’s and mad cow disease, turns out to play a significant role in cancer. In a paper published in Nature Chemical Biology, Frederic Rousseau and Joost Schymkowitz of VIB, K.U.Leuven and Vrije Universiteit Brussel describe that certain mutations of p53, [...]
