A neuroprosthetic device that uses relatively fewer electrodes to stimulate the parts of V1 corresponding to the fovea aims to:
A) guide movements visually.
B) optimize facial recognition.
C) reproduce the layout of ocular dominance columns.
D) compensate for the distortion caused due to cortical magnification.

Question

Quizplus · Accepted Answer

Cortical magnification refers to the way in which the amount of cortical area dedicated to processing the visual input from a given area of the visual field is not uniform but instead is much greater for the central vision (the fovea) than for the peripheral. A neuroprosthetic device that stimulates parts of V1 corresponding to the fovea with fewer electrodes aims to address this imbalance by compensating for the distortion caused by cortical magnification, thereby attempting to restore a more naturalistic perception of the visual field.
