Injured Spinal Neurons Reach Out To Each Other, But Not To Healthy Neighbors

Summary:
After injury, spinal neurons establish specialized bridges to connect with other injured neurons, according to new findings from researchers at the University of Pennsylvania Medical Center. Interestingly, the injured cells reach out only to each other in this process, excluding healthy neighboring cells from the network. The bridges - called gap junctions - are commonly found among neurons during development but are rarely seen in the adult mammalian nervous system.
