Figure (IMAGE) National Institute for Physiological Sciences Caption We can perceive familiar objects even when they become indistinct (A). After repeatedly encountering the objects, a subset of neurons in the primary visual cortex exhibits strong responses to low-contrast visual stimuli. These low contrast–preferring neurons substantially contribute to low-contrast visual information representation, ensuring a consistent perception of familiar objects with contrast variation (B).
