I have been greatly flattered and encouraged by the reception my research report on Aphantasia and SDAM in Cortex (preprint here at psyarxiv) has received. It's based on my talk (slides here, and sound here) at the "Eye's Mind" meeting at UEA, Norwich, UK in 2016.
I may supplement it with posts here from time to time, but for the moment it's a summation of what I have to say on the subject.
