Each random offset was drawn from a uniform distribution over the specified range. <i>C</i>: Images were generated by raising the power spectrum of the same pink noise images generated in <i>B</i> to a fractional exponent. This gradually transformed the pink noise images to white noise.</p> 2016-12-09 18:33:55 PCA brain areas population response changes Stimulus-Driven Population Activity Patterns Visual Cortex Dimensionality reduction recently-proposed V 1 dimensionality reduction analyses stimulus complexity population activity space
