Figure 6.
Relationship of sIAHP amplitude to performance on Delayed Recognition Span Tasks. Mean sIAHP amplitude in layer 3 pyramidal cells from a given monkey vs. the monkey’s performance on (A) DRST spatial and (B) DRST object behavioral tasks. Top: data from all monkeys, bottom: data from aged monkeys only. Bar graphs depicting mean sIAHP amplitude in layer 3 pyramidal cells from young monkeys and aged monkeys that were either unimpaired or impaired on (C) DRST spatial or (D) DRST object tasks. Dashed lines in A and B correspond to the level below which a subject is considered significantly impaired. * p < 0.02; ** p < 0.01.
