Scientists know very little about what causes synesthesia.
科學家對于“共感現象”的起因知之甚少。
While it appears to be hereditary, the actual neurological processes that account for the phenomenon remain a mystery.
雖然這種疾病看似遺傳,但實際上如何解釋這種現象的神經發生過程依然成謎。
Although most scientists agree that the hippocampus, an area of the brain responsible for memory, plays a role, exactly how the hippocampus might cause synesthesia is not clear.
盡管多數科學家們都認為大腦控制記憶的區域——“海馬體”是導致此現象出現的原因,但它如何影響并引發“共感”癥狀尚不清楚。
Otherwise, scientific knowledge about synesthesia is limited to several interesting observations.
另外,目前對“共同感覺”的科學認識僅基于幾種有趣的現象觀察。
For example, synesthetic perceptions remain consistent over time.
比如,這種“共同感覺”的感知會隨著時間保持一致。
In other words, if a person with synesthesia sees blue and green flashes when he hears a C-sharp, he will always see those same colors upon hearing that note.
也就是說,如果一個人聽到C大調時看到藍色與綠色閃過,那么只要他再聽到這一聲音,眼前會浮現藍色和綠色。
