Final answer:
Incoming visual stimuli are processed by feature detectors located in the occipital lobe's visual cortex.
Step-by-step explanation:
The feature detectors responsible for processing incoming visual stimuli are located in the occipital lobe's visual cortex. The primary visual cortex, which is part of the occipital lobe, is where visual information from the retinae is first received and processed. This area recognizes basic shapes and edges of objects, and also compares inputs from both eyes to extract depth information.
