Fig. 3. The hippocampus reverses cortical population adaptation in the conditioned context.

A–C Example of cortical population plasticity in the visual cortex, in homecage (A), or conditioned context in normal mice (B) or animals with HC lesion (C). Each dot shows the mean changes of signal intensity in a neuron subgroup. D The decay slope (as the dashed lines in A–C) of the activated neurons between the prior and the posterior section. n = 13 mice for home; 9 for HC-lesion; 17 for normal recall. Error bars, s.e.m.
