Potential new target identified for treating itch

School of Medicine researchers have found how sensory nerve cells work together to transmit itch signals from the skin to the spinal cord, where neurons then carry those signals to the brain. Their discovery may help scientists find more effective ways to make itching stop.
Understanding the network of connections between brain regions — as depicted above — and how they are changed by a stroke, is crucial to understanding how stroke patients heal, according to new research from Washington University School of Medicine in St. Louis. (Image: Joshua Siegel)

Measuring damage to brain networks may aid stroke treatment, predict recovery

Two new studies from the School of Medicine indicate that current clinical practices may be missing a key aspect of stroke-induced brain damage. For some cognitive functions, such as memory and attention, the severity of a person’s disability correlates with the extent of disruption to the brain’s communication networks – something that is not measured by most brain scans.
