Figure 6: Maturation of correlation strength and dimensionality across cortical areas.

a. Long-range correlations (1.8–2.2 mm) remain statistically significant versus control across age in all areas, while showing a significant decline with age in all areas except V1. Closed circles indicate experiments with significant correlations relative to shuffled controls. Open circles are non-significant at p<0.05. b. Dimensionality increases significantly with age in most cortical areas. Data from P21–24 animals in (a-c) replotted for comparison from (Powell et al., 2024).
