Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development. This research, supported by the National Institutes of Health, sheds light on how brain activity influences brain development, and highlights the newly found importance of the immune system in how the brain is wired, as well as how the brain forms new connections throughout life in response to change. Disease-fighting cells in the brain, known as...

A vast majority of cells in the brain are glial, yet our understanding of how they are generated, a process called gliogenesis, has remained enigmatic. Researchers at Baylor College of Medicine have identified a novel transcripitonal cascade that controls these formative stages of gliogenesis and answered the longstanding question of how glial cells are generated from neural stem cells. "Most people are familiar with neurons, cells that process and transmit information in the brain. Glial...

A type of cell plentiful in the brain, long considered mainly the stuff that holds the brain together and oft-overlooked by scientists more interested in flashier cells known as neurons, wields more power in the brain than has been realized, according to new research published today in Science Signaling. Neuroscientists at the University of Rochester Medical Center report that astrocytes are crucial for creating the proper environment for our brains to work. The team found that the cells...

(Ivanhoe Newswire)– Pill for spinal injury? A new study shows an oral drug that has shown promise in trials for human multiple sclerosis, significantly improves locomotor recovery in mice with spinal cord injury (SCI). Researchers uncover how a new pill that has shown positive results in mice with multiple sclerosis suffering from deterioration of the spinal cord, may help humans. Aside from the initial tissue damage, a great deal of the degradation of the spinal cord in SCI is...

Results reported in the American Journal of Pathology A new study suggests that administering FTY720, an oral drug that has shown promise in trials for human multiple sclerosis, significantly improves locomotor recovery in mice with spinal cord injury (SCI). The research suggests a possible new avenue to counteract the degeneration of the spinal cord in human SCI. The study will be published in the April 2012 issue of The American Journal of Pathology. Beyond the initial tissue damage,...

Researchers at the University of Copenhagen have documented a previously unknown biological mechanism in the brain's most important line of defense: the blood-brain barrier. Scientists now know that the barrier helps maintain a delicate balance of glutamate, a vital signal compound in the brain. The research results have just been published in the scientific journal GLIA. Glutamate is the most important activating transmitter substance in the brain. Vital in small amounts, it is toxic for...

Animal study suggests new strategy for treating depression Getting rid of a protein increases the birth of new nerve cells and shortens the time it takes for antidepressants to take effect, according to an animal study in the March 7 issue of The Journal of Neuroscience. The protein, neurofibromin 1, normally helps prevent uncontrolled cell growth. The findings suggest therapeutic strategies aimed at stimulating new nerve cell birth may help treat depression better than current...

A new study reveals a dazzling degree of biological diversity in an unexpected place — a single neural connection in the body wall of flies. The finding, reported in this week's online edition of the Proceedings of the National Academy of Sciences, raises several interesting questions about the importance of structure in the nervous system and the evolution of neural wiring. "We know almost nothing about the evolution of the nervous system, although we know it has to happen...

(Ivanhoe Newswire) -- Recent research has shown that Alzheimer's drugs, which are in clinical trials still, have adverse side effects. The drugs are designed to prevent BACE1, the enzyme Robert Vassar originally discovered that promotes the development of clumps of plaque associated with Alzheimer's.  BACE1 cuts up and releases proteins that form the plaque, making those who developed the drug believe that by blocking the enzyme the development of Alzheimer's disease might slow down....

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...

barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
