Researchers at the Del Monte Institute for Neuroscience at the University of Rochester find that microglia—the brain’s immune cells—can trigger cognitive deficits after radiation exposure and may be a key target for preventing these symptoms. These findings, published in the International Journal of Radiation Oncology*Biology*Biophysics, build on previous research showing that after radiation exposure microglia damage synapses, the connections between neurons that are important for cognitive behavior and memory.
