In foetal monkey brain neuronal projections carrying input from the two eyes initially overlap; they segregate during the second half of gestation and become fully separated in subcortical visual centres and partially separated in the cortex three weeks before birth and thus before visual experience.
在胎猴大脑中,携带来自双眼输入信息的神经元投射最初相互重叠;它们在妊娠后半期分离,并在出生前三周,也就是在视觉体验之前,在皮质下视觉中枢完全分离,在皮质中部分分离。
