- 요약Perception has been construed as the process of inferring the state of the environment from sensory input. In the case of vision, sensory input is encoded by a mosaic of rod and cone photoreceptors in the retina, with cones being crucial for color and spatial vision. The sensor array formed by the cones does not follow an intuitive design principle: long- (L), middle- (M), and short-wavelength sensitive (S) cones are placed randomly, and S cones are sparse while L and M cones can be present in very uneven amounts. The aim of the work presented here was to understand how this early encoding of sensory input affects basic features of color perception. The approach taken in each experiment was to measure perceptual responses to stimuli delivered within a region of an observer's cone mosaic. Simultaneously, the microscopic structure of the targeted region was imaged with an adaptive optics scanning laser ophthalmoscope. For some subjects, the spectral identities of individual cones were known at the stimulated locations. This approach allowed a direct comparison of cone spectral topography with visual behavior, which is an important step towards understanding the neural mechanisms that transform sensory input into perception.
