Synaesthesia is described as a neurological phenomenon which causes patients to simultaneously perceive one sense (e.g. hearing) generated by another (e.g. sight). Patients who suffer from Synaesthesia are known as synesthetes. A common symptom of this neurological phenomenon is the association of colours with an alphabet or number. Patients with this phenomenon might perceive the word ‘ferry’ in red or the number ‘8’ in yellow. Others have been recorded to experience taste elicited by certain objects for example, the taste of raspberries from the sight of tall skyscrapers. However, synthetic perceptions differ from each synesthetes as each perception renders unique to the individual. For instance, certain synesthetes may experience the association of the colour orange with the number 4 whereas other will disagree as they may experience the colour blue with the same number instead. There is no established diagnosis for this neurological phenomenon but experts in the field of this phenomenon belief that synaesthesia occurs due to the cross wiring in the brain. Scientists hypothesize that neurons and synapses that belong to a specific somatosensory system cross link and interact with another somatosensory system, hence highlights the association of two different senses experienced by synesthetes. Is it thought that the cross wiring is present at birth and declines with age due to a study depicting results of children demonstrating synaesthesia symptoms than adults. Therefore, it is evident that adult synesthetes are one of the few who do not lose the cross wiring senses but rather retains it. When it comes to specific parts of the brain that is involved in synaesthesia, it is believed by scientist Richard Cytowic (1989) that the l... ... middle of paper ... ...ver, several other systems have been shown to demonstrate similar characteristics thus are worth taking into account. One of them is the complement system as it involves an important role in grouping synapses for the process of pruning. Another system such as cytokines has proven in the involvement of neurogenesis and synaptic plasticity. Synaesthesia development through the immune system also leads to obtaining information that it puts synesthetes as high risk for clinical conditions. Studies performed by (Baron-Cohen et al., 2007) have shown that victims of autism tend to exhibit high levels of synaesthesia followed by Carruthers et al. (2012) findings on the relationship between the epidemic of synaesthesia and IBS. These findings therefore create a framework, establishing the relationship between immune synaesthesia and its association with clinical conditions.
