| Research Abstract |
Firing rates of neurons in cortex are highly variable from layer to layer and it is possible that the different firing rate is formed by different information representation. Introducing a novel information analysis framework using kernel principle component analysis(Kernel PCA) methods, neural activities in rat motor cortex were analyzed. As a result, this study shows that networks in superficial layer represent cue information using higher order correlation, while neurons in deep layer represent detailed motor information by simply its firing rate.
