Thank you, I totally agree on the VVIQ point (I also think we need a better measure) and that researchers should be more consistent in their cutoff criteria/definitions. This figure looks very interesting, I look forward to read your latest paper!

Hi! While I agree with your point, in our study (Cabbai et al., 2024) nearly all aphantasics (22/24) had a VVIQ score = 16 (the minimum), with only 2 slightly higher. Removing those 2 does not change the V1 spontaneous imagery decoding results.

Extensive work has shown that the visual cortex is reactivated during mental imagery, and that models trained on visual data can predict imagery activity and decode imagined stimuli. These findings ma...

the tldr of my thread is that, interoceptive sensing at rest has no relationship to mental health symptoms, and we think this is likely because we need to measure interoception during and after arousal, close in time to symptoms, with ecological measures.

Micah G. Allen @micahgallen.com · Aug 27

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇
