New paper with @statsepi.bsky.social and @deevybee.bsky.social in which we show there's really no evidence for a link between the gut microbiome and autism www.cell.com/neuron/fullt...
Conceptual and methodological flaws undermine claims of a link between the gut microbiome and autism
Claims that the gut microbiome causally contributes to autism regularly appear in the scientific literature and popular press. Mitchell et al. critically examine influential studies underpinning these...

Just out! ✨ Using a novel machine learning approach, we identify a developmental pathway by which the early life gut microbiome may shape mental health at school age via effects on functional brain development. This work can help identify microbial biomarkers of later health issues. 👉 rdcu.be/eNsUK
Childhood gut microbiome is linked to internalizing symptoms at school age via the functional connectome
