Describe how light is translated into neural impulses by our visual system.
Provide some real life examples!
Every human beings has 5 different sense organs. These are vision, hearing, taste, smell and touch. Human beings are continuously attacked by different forms of physical energy, including light, sound, heat and smell. Human brain is unable to detect these physical energy directly. So, in order to accomplish this task, highly specialized cells known as sensory receptors, that are located in our eyes, ears, nose, tongue and other places comes in action. Therefore, the light, sound, smell, taste that every human beings experience is the result of transduction. Transduction is a process of converting the physical energy into electrical signals or neural impulses which are then transmitted to our brain with the help of specialized receptor cells.
