Is interoceptive sensing unified across internal organs? 🫀🫁 Our high-powered psychophysical study (N=241) suggests not. Bayesian evidence indicates interoceptive processes are largely modality-specific—challenging the idea of a unitary interoceptive sense.

Background: when going off X/Twitter, I got out of habit of promoting my articles online. I’d like to highlight two articles on the cerebellum that I published in 2024, which also provides some context to my current call. I’m excited about revealing a cerebellum-behavioural correlation.

Looking for any papers that report a significant increase in any effect (not motor) in systole compared with diastole. I think I have an exhaustive list but just checking that I have not missed any. If you know of any please let me know. Thanks #interoception #cardiac
