Latest Neurobiology Stories
Scientists from The Scripps Research Institute have identified a new stem cell population that may be responsible for giving birth to the neurons responsible for higher thinking.
Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells.
Johns Hopkins researchers say they have discovered a cause-and-effect relationship between two well-established biological risk factors for schizophrenia previously believed to be independent of one another.
Transmission of nerve signals is enhanced in the insects that eat less
UC Santa Barbara scientists turned to the simple sponge to find clues about the evolution of the complex nervous system and found that, but for a mechanism that coordinates the expression of genes that lead to the formation of neural synapses, sponges and the rest of the animal world may not be so distant after all.
The brain receives information from the ear in a surprisingly orderly fashion.
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.
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...
