(Ivanhoe Newswire) -- The brain makes mistakes and then corrects them, according to a new study. A research group, led by Dr. Peter Scheiffele at the Biozentrum of the University of Basel, was able to document the brain's process of establishing a neuronal network that does not always prove precise or error-free. In the developing brain, countless nerve connections are made, which turn out to be inappropriate, and as a result, must eventually be removed. Using a genetic mouse model, the...

DALLAS -- Researchers at UT Southwestern Medical Center have identified a biochemical switch that affects how neurons fire in a part of the brain associated with learning, findings that may aid in understanding schizophrenia and Alzheimer's disease. The research sheds new light on the action of reelin, a protein known to be important in the nervous system. During development, reelin sends cues to migrating neurons, telling them where they're supposed to go. In adult mice, reelin has recently...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
