DCX and ischemia: The number of DCX-positive cells increased after hypoxia (the contralateral hemisphere is subjected to hypoxia, but not ischemia) and DCX counts revealed 13.6±0.6 cells/mm in the vehicle-treated group vs. 16.9±0.6 cells/mm in the lithium treatment group 12 weeks after HI (p = 0.0004) (Fig. 3).
