Y‐maze and object recognition memory test after chronic RF‐EMF exposure in mice of different ages. The Y‐maze test was used to evaluate spatial memory in 10M (months) (a) and 20M (b) mice. Alternation percentages indicate the frequency of nonoverlapping entries compared to the total number of entries into the three arms. (c and d) RF‐10M and RF‐20M groups exhibited equal preferences for the two test objects during training compared with age‐matched controls (data not shown). Novel object recognition was significantly improved in the 20M mice after chronic RF‐EMF exposure (d). Values represent the mean ± SEM (n = 12). Statistical significance has been defined as *p < .05 and **p < .01 Sham versus RF group. RF; RF‐EMF
