This study looks at the most common form of synesthesia, seeing the words you hear in color (colored hearing). Aleman et. al. aimed to find if the
primary visual cortex (V1) would be triggered when the subject heard a letter but did not have a visual stimulus in front of them. The subject in this study was a 32-year-old woman who reported having colored hearing since childhood. In the first test, she was asked to say what color she associated with each letter of the alphabet (alphabet-color test). Two years later, she was given the same test during an fMRI. Despite the time span, she only missed one letter, for a 96% accuracy rate, suggesting that she did have colored hear. Through the fMRI, the researchers were able to pinpoint the locations of activation, and confirm that the primary visual cortex (V1) was activated. These findings are consistent with recent theories about synesthesia.
