Transcription factor repairs neurons

The optic nerve is vital for vision — damage to this critical structure can lead to severe and irreversible loss of vision. Fengfeng Bei, PhD, a principal investigator in the Department of Neurosurgery at Brigham and Women’s Hospital, and his colleagues want to understand why the optic nerve — as well as other parts of the central nervous system including the brain and spinal cord — cannot be repaired by the body. 344 more words

This is what your brain does when forming memories

A team, led by researchers from the Cajal Institute (Madrid) belonging to the Spanish National Research Council (CSIC), have discovered some basic processes underlying memory consolidation in collaboration with colleagues at the National Hospital for Paraplegics in Toledo (Spain) and the University of Szeged (Hungary). 475 more words

Lighting up the brain

Many separate fields such microbiology, genetics, biochemistry, molecular biology and neuroscience have intersected to give rise to a new field called Optogenetics. Quite simply, optogenetics involves using genes to help single cells make light sensitive proteins. 1,001 more words

Using information theory to understand the brain

Despite advances in neuroscience, the brain is still very much a black box–no one even knows how many different types of neurons exist. Now, a scientist from the Salk Institute has used a mathematical framework to better understand how different cell types divide work among themselves. 509 more words
