What do amacrine cells process?

• A. Color detection.
• B. Temporal processing and motion detection.
• C. Light absorption.
• D. Aqueous humor production.

Answer: (B)

Amacrine cells are retinal interneurons that shape the timing of the visual signal between bipolar cells and retinal ganglion cells. Their inhibitory and modulatory input fine-tunes how responses evolve over time, which is essential for detecting changes and movement in the visual scene. Specialized amacrine cells contribute to direction-selective circuits, helping ganglion cells respond preferentially to motion in specific directions. Color detection, on the other hand, comes mainly from photoreceptors (cones) and their pathways, while light absorption and aqueous humor production involve photoreceptors and the eye’s anterior segment, respectively, not amacrine processing.
