Grapheme-colour synaesthesia and enhanced cortical excitability – I find this research quite exciting, but maybe that’s just me

“He found that neurons in the primary visual cortex were more active than expected.”

This is a quote about a study of some grapheme-colour synaesthetes. I’m a grapheme-colour synaesthete, and I’m wondering if this enhanced cortical excitability in the primary visual cortex which they wrote about in New Scientist last November is also an explanation for my superior face memory and the many other atypical visual perception experiences that I’ve had, and have described in this blog. It’s exciting research.
