(A) Averaged ratio of scores (± SEM) on the 4-SOMT probe trials for sham-operated controls (Group Neo-C, white bars) and monkeys with neonatal hippocampal lesions (Group Neo-Hibo, black bars). Scores are cumulative correct responses on the inner object discrimination (2 vs 3) divided by the number of correct responses on the outer discrimination (1 vs 4) across the three-day probe sessions. A score near one indicates equivalent performance on the two trial types, whereas a score below one indicates poor performance on the inner object discrimination. * indicates p = 0.002. (B) A graph of the correlation between the extent of hippocampal lesion and the ratio score earned on the 4-SOMT probe test (r = 0.820, p = 0.046), however it is clear that this correlation is driven by one individual (Neo-H-3 highlighted with a circle), and this correlation does not remain when this animal is removed from the analysis (r = 0.698, p = 0.199).
