Feeling sound

Summary:
           Scientists believe that some of the five senses in the brain have common circuits and are related. Scientist conducted an experiment to show that subjects' hearing is affected when vibration patterns are introduced to their fingertips. Subjects had difficultly telling the different pitched sounds apart when the vibration intensity also changed. Scientists concluded that the brain combined the information that the ears and fingers sent.

Connection to class:
          We recently learned about the nervous system and how parts of our body send nerve signals to the brain. We also learned about parts of our body like our ears and how they send signals to the brain.
