5.1.1.5. Taste 
The stimulus for taste consists of substances that penetrate into the taste buds in 
the tongue and mouth. This is reflected in the property yes
> in Section 5.2.2. In 
order to taste the mouth has to be in contact with the OP, but tasting can be considered a 
voluntary act, because it is the PR’s decision to actually put the OP that contains these 
substances into the mouth. These two characteristics are represented by the properties 
yes
> and yes
> in Section 5.2.2. These substances must be soluble in 
saliva in order to be tasted. The taste buds are the responsible receptor cells for the 
reception of chemical substances. Some of them are situated in the papillae, the little 
bumps in the tongue, in the roof of the mouth, inside the cheeks, and in the throat. The 
most sensitive part, however, is the tip of the tongue; this can identify tastes in only a 
couple of seconds. The property yes
> in Section 5.2.2 reflects this fact. The 
number of taste buds varies across individuals (Miller and Reedy 1990) and they are in a 
constant process of degeneration and replacement by new ones (Beidler and Smallman 
1965). Each bud contains an average of fifty individual taste receptor cells. Each of 
these cells has a threadlike structure called a microvillus at their end. When these 
microvilli come into contact with taste solutions, an electrical potential is triggered in 
the receptor cell. Back inside the papilla, the taste receptor cells make contact with nerve 
fibres innervating the tongue, as they themselves do not have the axons to send messages 
to the brain. Taste buds in the tongue and mouth are innervated by no less than three 
distinct cranial nerves, sometimes even more than one nerve innervates the same taste 
bud (Keverne 1982); as a consequence, taste information arrives at the brain over several 
different communication lines. In the brain, there are two sections involved: on the one 
hand, the insular cortex – located between the temporal and parietal lobes – whose 
activity triggers the conscious experience of tastes; and on the other, part of the limbic 
system, which registers some behaviourally relevant information about taste. As seen in 
the case of smell, this is a possible explanation for the differences in the aesthetic 
judgements of the PRs in reference to the classification of tastes, both physically and 
metaphorically. This is represented by the property yes
> in Section 5.2.2.
