    Central and peripheral vision show similar spatiotemporal performance when normalized for cortical magnification. This suggests underlying similarities in visual processing across the retina.

    Area of Science:

    • Neuroscience
    • Vision Science
    • Visual Perception

    Background:

    • Photopic vision's contrast sensitivity varies between central (foveal) and peripheral retina.
    • Understanding these variations is key to comprehending visual processing across the entire visual field.

    Purpose of the Study:

    • To investigate the spatiotemporal contrast sensitivity functions in both foveal and peripheral photopic vision.
    • To determine if quantitative differences in sensitivity are inherent or due to differing retinal representations.

    Main Methods:

    • Measured temporal and spatial contrast sensitivity functions at multiple nasal visual field eccentricities.
    • Normalized visual stimuli (gratings) using the cortical magnification factor (M) for area, spatial frequency, and velocity.
    • Tested various temporal modulations (0-25 Hz) and threshold tasks (detection, discrimination).

    Main Results:

    • Sensitivity decreased with eccentricity without normalization.
    • Normalized temporal contrast sensitivity functions became similar across all eccentricities.
    • Normalization proved effective across diverse temporal modulations and tasks.

    Conclusions:

    • Central and peripheral vision exhibit qualitatively similar spatiotemporal performance.
    • Quantitative differences without normalization stem from retinal ganglion cell spatial sampling properties related to cortical magnification.
