What Happens in a Mind That Can't 'See' Mental Images

Yasemin Saplakoglu (2024). Feature article, Quanta Magazine.

This is a long-form science piece from Quanta Magazine that does a really nice job of introducing aphantasia to a general audience without dumbing it down. It follows several researchers who stumbled into the field, including a vision scientist who discovered her own aphantasia mid-seminar, and traces how the science has evolved from simply proving the condition exists to trying to understand the brain differences behind it. It also covers hyperphantasia, the opposite end of the spectrum, and makes the case that everyone sits somewhere on a continuum.

What makes this piece stand out is how honestly it holds the uncertainty. Researchers find that people with aphantasia have weaker connections between their brain's control centers and visual processing areas, but the visual cortex itself is often more active, not less. The information seems to be there. It just can't be pulled into conscious experience.

Nobody fully understands why yet, and the article doesn't pretend otherwise. It's also refreshingly clear that aphantasia is not a disorder, it's a variation, and some researchers even suggest it might come with advantages in certain areas of mental health.

If you remember one thing: The brain in aphantasia isn't missing visual information. It just can't get that information to show up as a picture, and nobody yet fully understands why.
