A comparison between non-synaesthetes and grapheme–colour synaesthetes based on the stochastic resonance model. Synaesthetes have higher levels of noise in the colour processing network, which leads to stochastic synchronization between the VWFA and colour processing network. The colour processing areas also have greater cortical excitability and increased connectivity with other frontoparietal areas in non-synaesthetes. (Online version in colour.)
