Simple cells in the primary visual cortex:
A) have ratios of responding that code different visual features
B) have the same firing rate for any visual feature
C) are specialized for detecting lines in certain orientations
D) lack the ability to detect differences, such as corners, in visual features

Question

Quizplus · Accepted Answer

Simple cells in the primary visual cortex are specialized for detecting lines in certain orientations, such as vertical or horizontal lines. They accomplish this through their ability to respond preferentially to specific orientations of light or dark bars within their receptive field. Therefore, these cells do not have the same firing rate for any visual feature and are not limited to coding specific ratios of responding. They also have some ability to detect differences in visual features, such as corners, although this is not their primary function.
