Scientists found a strong connection between the size differences in specific areas of the brain (the hippocampus) and how people scored on a visual imagery questionnaire

thank you so much! To be honest I would love to have my aphantasia properly 'diagnosed' with some sort of brain scan.

Mee too, while one of these two might be interesting to be evaluated:

Pupillary response: The pupillary light response as a physiological index of aphantasia, sensory and phenomenological imagery strength: https://pmc.ncbi.nlm.nih.gov/articles/PMC9018072/
Skin conductance: https://pubmed.ncbi.nlm.nih.gov/33715433/
Binocular rivalry: https://pubmed.ncbi.nlm.nih.gov/29175093/ (see also https://aphantasia.com/article/science/binocular-rivalry/ )

I have seen some of these studies! It's really cool. It's fun to think that maybe one day my neurodivergency may be proven neurologically. thanks for your insight!
