Defining synaesthesia and some interesting research findings – a lecture by a leading Aussie synaesthesia researcher

Below is a link to a webpage that has a video of Associate Professor Anina Rich from Macquarie University delivering the Paul Bourke Lecture 2014 and answering questions afterwards. Some other speakers have a few things to say before her lecture. Associate Professor Anina Rich is the winner of the 2013 Paul Bourke Award for Early Career Research.


Oh look! Article in fascinating “Mindscapes” series in New Scientist about prosopagnosia

Autobiographer Heather Sellers is profiled, prosopagnosia is described, leading face memory researcher Brad Duchaine is interviewed and a brain scan study of his is described, an interesting study by Italian researcher Zaira Cattaneo using transcranial magnetic stimulation is outlined. Nice work, Helen Thomson! I wonder whether a super-recognizer might in the future be featured in this series? I can only guess.

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.
