Late Maturation of Adult-Born Neurons in the Temporal Dentate Gyrus

Figure 3

Timecourse of Arc expression across subregions.

a) Expression of Arc in adult-born granule neurons was age-dependent and occurred earlier in the septal DG than in the temporal DG (effect of cell age F5,19 = 53, P<0.0001; effect of septotemporal subregion F1,19 = 35, P<0.0001; interaction F5,19 = 7, P<0.001). b) There were no differences between blades in the septal DG (effect of cell age F5,19 = 33, P<0.0001; effect of blade F1,19 = 3, P<0.1; interaction F5,19 = 0.1, P = 1). P<0.1, **P<0.01, ***P<0.001 post hoc vs. temporal value at same time point.
