Signal transduction in vision is the process by which light is converted into electrical signals that can be interpreted by the brain. This process involves several steps:
1. Light enters the eye and passes through the cornea and lens, which focus the light onto the retina at the back of the eye.
2. The retina contains photoreceptor cells called rods and cones, which are responsible for detecting light. When light hits these cells, it triggers a series of chemical reactions that result in the generation of electrical signals.
3. The electrical signals are then transmitted to the bipolar cells and ganglion cells in the retina, which further process the signals before sending them to the brain via the optic nerve.
4. The optic nerve carries the electrical signals to the visual cortex in the brain, where they are interpreted as visual information.
Overall, signal transduction in vision involves the conversion of light into electrical signals, the processing of these signals in the retina, and the transmission of the signals to the brain for interpretation.
