The feature detectors identified by hubel and wiesel respond to specific aspects of visual stimulation.
The answer is visual because with that stimulation they tried to find out the effect of unilateral vision on the primary visual cortex of the brain. According to the work done, it was suggested that if the developing brain is not exposed to superimposed images of the two eyes, it will never form the connections you need to process a three-dimensional scene. The purpose of the experiment was to find out how the brain can develop complex visual images.
