a, Following recent fear memory recall, ADn activity was positively correlated with activity in the majority of the other 83 brain regions. (bars: correlation between ADn and a given region; green line and shaded region: mean correlation between other 83 non-ADn brain regions and a given region ± s.e.m,). b, At the remote time point, ADn activity became strongly inversely correlated with activity in the majority (78/83) of other 83 brain regions. (bars: correlation between ADn and a given region; blue line and shaded region: mean correlation between other 83 brain regions combined and a given region ± s.e.m.). Data were obtained from Wheeler et al., 201311.
