Rod Bipolar Cells

Rod bipolar cells are specialized nerve cells in the retina that help detect low-light conditions, such as nighttime or dim environments. They receive signals from rod cells, which are sensitive to light but do not detect color. When rods absorb light, they send signals to rod bipolar cells, which then process and relay this information to other cells, eventually reaching the brain. This pathway allows us to perceive shapes and movement in darkness but without color detail. Rod bipolar cells are essential for night vision and function primarily when lighting is scarce.
