Abstract
The neuronal correlate of a rare explicit bi-directional synaesthesia was investigated with numerical and physical size comparison tasks using both functional magnetic resonance imaging and event-related potentials. Interestingly, although participant I.S. exhibited similar congruity effects for both tasks at the behavioural level, subsequent analyses of the imaging data revealed that different brain areas were recruited for each task, and in different time windows. The results support: 1) the genuineness of bi-directional synaesthesia at the neuronal level, 2) the possibility that discrepancy in the neuronal correlates of synaesthesia between previous studies might be task-related, and 3) the possibility that synaesthesia might not be a unitary phenomenon.
