Science of the Senses

Science of the Senses

Sight. Hearing. Touch. Taste. Smell. The five senses are so easy to remember that kindergarteners can rattle them off. But understanding how they tell us about the world around us, or how the others compensate when one sense is lost to us, is far more complex. Our five senses, combined with our brain and the rest of the nervous system, give us clues about both what is safe, enjoyable, and comforting and what is dangerous, scary, and unpleasant. Without them, the world would be a far harder place to comprehend.

Below, Science NetLinks offers you a taste (and a look, listen, smell, and feel) of some of our sense-related resources.
