If a researcher inserts a recording electrode into V1 perpendicular to the surface of the cortex so that the electrode encounters neurons within a single column, the person in such a situation will encounter receptive fields of those neurons:
A) at adjacent locations on the retina.
B) at about the same location on the retina.
C) corresponding to the center of the fovea.
D) occupying equal areas of the retina.

Quizplus · Accepted Answer

When a recording electrode is inserted into V1 perpendicular to the surface of the cortex to encounter neurons within a single column, the receptive fields of those neurons will be at about the same location on the retina. This is because cortical columns in V1 are organized such that neurons within a column process information from the same location in the visual field, reflecting a specific part of the retina.
