Effects on memory retrieval or on retention day in the Morris water maze test of curcumin (CUR) in a 300 mg/kg per day chronic IP injection. Data shows the percentages of time spent (a) and distance (b) in the target area. This test was performed 10 days after the acquisition days. STZ-induced animals showed weaker memory performance in all parameters tested compared to the SHAM and CUR-treated STZ-induced groups (n = 7–8). *P < 0.01 for SHAM vs STZ + vehicle (Vh), # P < 0.05 for STZ + CUR vs STZ + Vh
