CHAPTER 6
Placing wine in your mouth is an action that sometimes seems irrelevant, but it is a journey full of somatosensory stimuli. It may be less noticeable than sound, but depending on the weight, shape or colour of the tasting tool, the perception of the act will be very different. Even the degree of inclination of the head when drinking influences perception. Therefore, it is important to explain the anatomy and functioning of the arm to see which nerve impulses encode the act of holding a glass, and how its path to the mouth affects perception. This is a complicated chapter, because it addresses great unknowns such as the somatosensory system, as well as the functioning of our sense of balance, essential for awareness of spatial position and the movement of the head.
