Figure 4. Radiated animals are impaired in both learning and memory retention at 5 months post-treatment.

A schematic of the experimental design is shown in (A). Impairments in acquisition of the task, indicated by increased primary errors (B) and primary latencies (C) are observed in the radiated group. Representation of primary errors (D) and primary latency (E) over individual trials. (F) Long-term learning retention is impaired in the radiated group. Data represent Mean ± SEM. *p<0.0031; ^#p<0.006 vs. controls. N = 8–10 animals per group.
