Rods are the sensory device that detects the illumination. They are over the whole width of the retina. In some animals such as cats, they have a special reflective layer behind the retina so that the sensors have a second go at the light. This feature, and the size of their pupil means that cat's night vision is about six times more sensitive than humans. (But they don't see colour as well as humans.)
For people with normal vision, that would have to be light.For people with impaired vision or no vision, I'd say heat.Heat and light are the only electromagnetic radiation thathumans can detect physiologically. You might go way outand say that after light and heat, the next one is radio.
Direct vision is your central vision. It refers to how and what you see when looking straight at an object. Indirect vision refers to your peripheral vision, which means the things you see "out of the corner of your eye" or off to the side while you are looking directly ahead.
i think the study of light and vision is optics. Im pretty sure.
The sensory areas for vision are found in the occipital lobe.
The human eye contains specialized receptor cells that are responsible for night vision. These cells are referred to as rods.
I- Olefactory (sensory): smell. II- Optic (sensory): vision.
Retina in the eye contains sensory cells. Retina has got rods and cones. Cones are responsible for colour vision. Rods are responsible for vision in less amount of light.
The sensory nervous systems main function is to process any sensory information. Vision, hearing, touch, taste, smell, and movement are the things that this system processes.
The peripheral vision allows snails to see from behind.
Focal or Focus Vision
1. The main organ of the sensory system, in terms of human dependence on it, is vision. 2. The largest organ of the sensory system is the skin (touch, warm, cold, prickly, etc.)
It depends on what the receptor cells are for. If they are for vision, they are located in the retina of the eye. If they are for hearing, they are located in the organ of Corti, and so on and so forth.
