THERE’S nothing quite like the smell of coffee brewing, or freshly baked bread hot out of the oven. What we choose to eat is very often determined by what smells good and what tastes appealing. The senses of smell and taste have a close relationship and are both key to our enjoyment of food. • Gustatory (taste) nerve cells are clustered in the taste buds of the mouth and throat. These cells send taste information to nearby nerve fibres, which transmit messages to the brain.
