How about this: wikipedia.frost_zero said:How do the rods and cones in your eyes work? I looked it up but didn't find any detailed explanation
Individual photoreceptors can be hooked up to electrodes, in labs, in small numbers, but they are not likely to replace electronic sensors in cameras.frost_zero said:could we make them artificially to use like cameras?
Rods and cones are two types of photoreceptor cells located in the retina of the eye. Rods are responsible for detecting light and dark, while cones are responsible for color vision. These cells work together to convert light into electrical signals that are sent to the brain, allowing us to see images and colors.
Rods are more sensitive to light and are responsible for our ability to see in low light conditions. They are also more numerous in the retina, with around 120 million rods compared to 6 million cones. Cones, on the other hand, are responsible for our color vision and are more concentrated in the central part of the retina, known as the fovea.
Rods are most active in low light conditions, such as at night, and are responsible for our ability to see in dimly lit environments. Cones, on the other hand, are most active in bright light conditions and are responsible for our ability to see colors and fine details.
No, the number of rods and cones in our eyes is fixed from birth and does not change throughout our lifetime. However, the function and health of these cells can be affected by various factors, such as age, genetics, and certain diseases.
The signals from rods and cones are sent to the brain through the optic nerve. The brain then combines and interprets these signals to create the images that we see. This process involves various areas of the brain, including the visual cortex, which is responsible for processing visual information.
