Why are special senses important?
The principle function of the special sensory receptors is to detect environmental stimuli and transduce their energy into electrical impulses. These are then conveyed along sensory neurons to the central nervous system, where they are integrated and processed, and a response is produced.
What are the 4 special senses?

Why do we need sensation?
We need the combined input from our senses to tell us about what is happening in the world around us.

For example: Our sense of smell might tell us that milk has turned sour so we do not drink it.
How do our senses work?
How do the senses work? Your brain collects information, like smells and sounds, through your five senses: sight, hearing, touch, taste, and smell. Each of your five senses has its own special sensor. Each sensor collects information about your surroundings and sends it to the brain.
Can you improve your senses?
In time, and with training, you can learn to make maximum use of all your senses — touch, hearing, smell, and any remaining vision — as well as improve your visual memory.
