Ohshiro, Hussain, and Weliky (2011) recently showed that ferrets reared with exposure to flickering spot stimuli, in the absence of oriented visual experience, develop oriented receptive fields. They interpreted this as refutation of efficient coding models, which require oriented input in order to develop oriented receptive fields. Here we show that these data are compatible with the efficient coding hypothesis if the influence of spontaneous retinal waves is considered. We demonstrate that independent component analysis learns predominantly oriented receptive fields when trained on a mixture of spot stimuli and spontaneous retinal waves. Further, we show that the efficient coding hypothesis provides a compelling explanation for the contrast between the lack of receptive field changes seen in animals reared with spot stimuli and the significant cortical reorganisation observed in stripe-reared animals.
大代野博，侯赛因，和韦利基（2011 年）最近表明，雪貂在没有定向视觉体验的情况下，通过接触闪烁点刺激进行饲养，会发展出定向感受野。他们将这一结果解释为对有效编码模型的反驳，因为有效编码模型需要定向输入才能发展出定向感受野。在这里，如果考虑自发视网膜波的影响，我们表明这些数据与有效编码假说相符。我们证明，当在点刺激和自发视网膜波的混合物上进行训练时，独立成分分析主要学习到定向感受野。此外，我们还表明，有效编码假说为在点状刺激饲养的动物中观察到的感受野变化缺失与条纹饲养的动物中观察到的显著皮层重组之间的对比提供了一个令人信服的解释。
