Relative object strengths as a function of time in both tasks, separate recording sessions. A, The percentage variance explained by the first or the second object during the recognition task, averaged across the population of neurons. During the two-object delay period, the most recently seen object has a stronger representation. B, The same analysis during the recall task. Now, the most recent object has a weaker representation during the two-object delay. C, The object 1 curve minus the object 2 curve for both tasks. The relative strengths of the object representations during the two-object delay depend on which task the monkeys are performing. The shaded gray area indicates a significant difference in relative strengths (two-sample t test, p < 0.05).
