Figure 3.

Effect of rostrocaudal position within PRc on memory impairment induced by kynurenic acid (KYNA). Performance (as measured by percentage correct trials) as a function of delay (10, 30, and 60 represent individual delays in seconds). Anterior condition targeted infusions to the medial PRc at levels +18, +16, and +14 from the interaural line as outlined in Figure 1. Posterior condition targeted infusions to the medial PRc at levels +16, +14, and +12. * indicates significantly different from10 s and ^∧ indicates significantly different from the equivalent delay under saline-infused conditions. Bars represent means (+SEM). Open symbols overlaid on the bar graphs represent individual monkeys and correspond to those used in Table 1.
