Final answer:
Feature detectors in the visual cortex are responsible for analyzing specific aspects of the retinal image, such as angles and movements. Retinal ganglion cells are the ones that form the optic nerve. Rods and cones are the two types of photoreceptors in the retina with different functions in visual perception.
Step-by-step explanation:
Feature detectors in the visual cortex analyze the retinal image and respond to specific aspects of shapes, such as angles and movements. Feature detectors are specialized neurons in the brain that are tuned to specific stimuli in the environment. They allow us to recognize various aspects of our visual world.
Axons from retinal ganglion cells make up the optic nerve, which is the pathway for visual information from the eye to the brain. Moreover, when light enters the retina, it passes through the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye.
The two main types of photoreceptors are rods and cones. Rods are extremely sensitive and can detect motion and provide vision in low-light conditions, but do not contribute to color vision; whereas cones are responsible for color vision and function best in bright light.
