synaesthetic phenomena than the average. 16 However, it may also be that pharmacologically<br />

induced synaesthesia is not based on the same neural mechanisms as the congenital, lifelong<br />

experiences of synaesthetes, in spite of the superficial similarities. Also, not everyone who<br />

uses these drugs experiences synaesthesia. It is possible that a genetic predisposition is<br />

required for this perception to take place. 17<br />

Synaesthesia seems to be six times more frequent in females than in males. 18 One wonders<br />

whether this is in any way related to the fact that colour-defective vision is also a hundred<br />

times more common amongst white males than amongst white females. 19 There is also<br />

indication that there is a much higher incidence of synaesthesia amongst fine artists (23%<br />

according to certain experiments). 20 Also amongst people practicing Zen meditation on a<br />

regular basis there is a higher percentage, as a recent experiment has shown. 21<br />

People with one type of synaesthesia are more likely to also have a second or third type. It<br />

frequently runs in families, which indicates that it is genetically based. Family studies show<br />

that the trait seems to be passed along the X-chromosome.<br />

2.3 Synaesthesia as a universal phenomenon<br />

As mentioned above, children usually have stronger synaesthetic reactions than adults.<br />

According to researchers, the brain of newborn babies does not differentiate between the<br />

various senses, but rather experiences sensory impressions as a single whole. It is only after<br />

the 5 th or 6 th month after birth that the senses start to differentiate. 22 However, taste and smell<br />

never get entirely separated: they closely interact throughout the lifetime of a human.<br />

Rather than looking at synaesthesia as a neurological oddity, several researchers 23 have more<br />

recently started to investigate synaesthesia as a mode of perception, which lies in the<br />

evolution of every human being. The study of synaesthesia has thereby revealed new<br />

neurological insights about the functioning of the brain.<br />
