Spatial memory deficits are evident in infected mice both 10 and 40 days after cessation of treatment with antimalarial drugs. (A) Infected mice (PbA) had significantly lower preference scores in the object placement test of spatial memory when assessed after a 30 min retention interval or (B) after a 120 min retention interval. (C) A significantly higher percentage of the infected mice performed at random levels (preference score of 55% or lower = no pref, preference score higher than 55% = pref) after the 30 min retention interval at both time points and (D) at 120 min retention interval. *p < 0.05.
