Table 5. Chronic visual deprivation does not affect the numerical densities of ERα-positive cells across cortical layers of V1.

Layers/Group	Dark-Reared	Normally-Reared
Supragranular	15.3±1.9	14.8±1.6
Granular	16.3±1.5	16.1±1.6
Infragranular	17.3±1.6	17.5±2.1

Data are expressed as mean ×10³ neurons/mm³ ± S.E. No significant differences were detected across groups for all cortical layers (all p>0.05).
