WELLESLEY, Mass., Aug. 18, 2014 /PRNewswire-USNewswire/ -- A new study by Barbara Beltz, the Allene Lummis Russell Professor of Neuroscience at Wellesley College, and Irene Soderhall of Uppsala University, Sweden, published in the August 11 issue of the journal Developmental Cell, demonstrates that the immune system can produce cells with stem cell properties, using crayfish as a model system. These cells can, in turn, create neurons in the adult animal. The flexibility of immune...

Salk Institute Scientists hope to borrow strategy from simpler animals to repair damaged spinal cord nerves in humans Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is—while many animals have this ability, humans don't. But new research from the Salk Institute suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits. Such a feat could eventually lead to therapies for the...

Researchers at UC Davis School of Medicine have for the first time shown that a polysialylated glycoprotein that regulates neurodevelopment exists on the surface of cells in the adult inner ear. Sacramento, Calif. (PRWEB) July 15, 2014 Researchers at UC Davis School of Medicine have for the first time shown that a polysialylated glycoprotein that regulates neurodevelopment exists on the surface of cells in the adult inner ear. This biomarker of early cells allows researchers to identify...

Ohio State University Study in mice suggests immune cells fail to activate key messenger needed for repair In the complex environment of a spinal cord injury, researchers have found that immune cells in the central nervous system of elderly mice fail to activate an important signaling pathway, dramatically lowering chances for repair after injury. These studies were the first to show that spinal cord injuries are more severe in elderly mice than in young adults, corroborating...

Cold Spring Harbor Laboratory There are new clues about malfunctions in brain cells that contribute to intellectual disability and possibly other developmental brain disorders. Professor Linda Van Aelst of Cold Spring Harbor Laboratory (CSHL) has been scrutinizing how the normal version of a protein called OPHN1 helps enable excitatory nerve transmission in the brain, particularly at nerve-cell docking ports containing AMPA receptors (AMPARs). Her team's new work, published June 24 in...

University of California - San Diego Some neurons turn to neighbors to help take out the trash It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School of Medicine and Kennedy Krieger Institute have discovered that some neurons transfer unwanted mitochondria – the tiny power plants inside cells – to supporting glial cells called astrocytes...

Alan McStravick for redOrbit.com - Your Universe Online The flight of a fruit fly, as determined by a recent study, is dependent upon whether or not the fly perceives a threat. Scientists at the Howard Hughes Medical Institute's Janelia Research Campus have successfully discovered the brain processes engaged in standard flight and the more rapid escape flight. A quick-escape circuit in the fly's brain overrides the slower, more controlled behavior as a threat looms large over the...

Brandeis University A new model to understand neural self-regulation When your car needs a new spark plug, you take it to a shop where it sits, out of commission, until the repair is finished. But what if your car could replace its own spark plug while speeding down the Mass Pike? Of course, cars can't do that, but our nervous system does the equivalent, rebuilding itself continually while maintaining full function. Neurons live for many years but their components, the proteins...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
