Erythropoietin hippocampal tissue concentration changes in mice exposed to room air (normoxia, RA), IH, and SH for 1, 3, 7 and 14 days, and after administration of exogenous EPO (EPO Tx) for 14 days in RA and IH-exposed mice. (n = 8/experimental group; * - p < 0.01 SH vs. RA or IH; # - p < 0.05 IH vs. RA; ** - p < 0.01 EPO Tx vs. RA and IH).
