A new study finds that the ear delivers sound information to the brain in a surprisingly organized fashion The brain receives information from the ear in a surprisingly orderly fashion, according to a University at Buffalo study scheduled to appear June 6 in the Journal of Neuroscience. The research focuses on a section of the brain called the cochlear nucleus, the first way-station in the brain for information coming from the ear. In particular, the study examined tiny biological...

A protein produced by the central nervous system´s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm. Seth Blackshaw, Ph.D., an associate professor in the Solomon H. Snyder Department of Neuroscience at the...

A molecule responsible for the proper formation of a key portion of the nervous system finds its way to the proper place not because it is actively recruited, but instead because it can't go anywhere else. Researchers at Baylor College of Medicine have identified a distal axonal cytoskeleton as the boundary that makes sure AnkyrinG clusters where it needs to so it can perform properly. "It has been known that AnkyrinG is needed for the axon initial segment to form. Without the axon...

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...

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...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
