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

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).

数据以均值×10³个神经元/立方毫米 ± 标准误（Standard Error）的形式表示。所有皮层层的各组间均未检测到显著性差异（所有p>0.05）。
