Causal clarity and deeper dimensions in microbiota-gut-brain research

Abstract

AbstractOur analysis of microbiota-gut-brain (MGB) research took MGB to task for some of its methods, concepts, and interpretations. Commentators then raised numerous issues about the neuroscientific and microbiome aspects of MGB and how it can be understood as a field. We respond by addressing the dimensionality (scope and depth) and causal focus of MGB.
