Results using this technique (which have been reported in previous RLE Progress Reports), show that the TM behaves as a gel. The material properties of a gel are a direct consequence of its molecular architecture. Cha ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
