Primary Visual Cortex Function

When light enters the human eye, it is first refracted through the cornea and then further focused by the lens onto the retina, where photoreceptor cells convert the light into neural signals. These signals are then transmitted to various parts of the brain for processing. One area critical in interpreting the visual information is the primary visual cortex (V1), which has specialized neurons that respond to specific aspects of the visual stimuli like edge orientation and motion. Understanding the function of V1 and its associated pathways is crucial for grasping how humans perceive complex visual information.

Given this context, which aspect of visual perception is primarily associated with the processing of orientation and movement in the primary visual cortex?
