The paper shows that passive exposure to images increases sparseness in primary visual cortex neural activity by reducing responses of less active neurons.

The paper shows that V1 neurons encode not only the current visual stimulus but also information from up to five previous images, with effects lasting up to 1000 msec.

The paper investigates predictive coding in the primary visual cortex by analyzing neural responses to novel and familiar stimuli in mice, finding a two-channel code for stimulus identity.
