Role of retina in the development of micro-temporal patterning. A, Representative dEEG during active periods and multiunit spike rasters through the depth of cortex. Activity periods were chosen to best represent spectral differences. B, Mean ± SD spectral power distributions by age group. Green lines show frequencies with significant (p < 0.05) differences between groups calculated by permutation analysis. Enucleated animals show reduced spindle-burst frequency at P8 and increased power in slow frequencies and reduced high-frequency power beginning at P14.
