Fig. 4From: Short- and long-term effects of 56Fe irradiation on cognition and hippocampal DNA methylation and gene expressionThe percentage of Arc-positive neurons in the CA3 region of the hippocampus at the 2-week time point. There were no effects of dose or trend towards group difference between dose conditions in mice following exposure to twice the same environment and following exposure to different environments. b The total number of Arc-positive neurons in the CA3 region of the hippocampus at the 2-week time point. There were no effects of dose or trend towards group difference between dose conditions in mice following exposure to twice the same environment and following exposure to different environments.
