视知觉训练与初级视皮层神经元信息及其表征容量

通过分析猕猴初级视皮层（V1）神经元的群体活动在轮廓线检测训练过程中的变化发现：知觉训练可以降低V1神经元响应在不同试次之间的变异性，促使V1神经元对相同刺激的响应更加稳定；训练还可降低V1神经元群体中神经元活动之间的相关性，使V1神经元之间的活动更加独立；增加了神经活动的维度，提高了神经元表征信息的容量，减少了冗余的神经活动，进而提升了感知能力.

Perceptual learning enhanced the coding capacity of primary visual cortex in rhesus monkey

Perceptual training was found to reduce variability of primary visual cortex (V1) in rhesus monkey neuron response among different trials with identical stimulus, indicating response to the same stimulus became more stable．Meanwhile, correlation between neuronal activities was found to be decreased, indicating that activities between neurons became more independent, and perceptual training increased the dimensionality of neural population, thus improved capacity of neuronal representation information．Therefore, perceptual training increased stability of neuronal response to stimuli, reduced redundant neural activities, increased capacity of neuronal information representation, and improved perceptual ability．
