So, interesting as the article is, there are two layers of caution one must exercise in interpreting the results. #1. The experiments were conducted in mouse models. Mouse models are remarkably useful, but are NOT human equivalents. It's dangerous to draw a straight line between human behaviour and behaviour in mice. [1] #2. Gut microbiome is the latest in the hype train. It may be important, but again, drawing such a straight (even speculative) line between gut microbiomes and behaviour is.. a reach [2,3,4]. Basically, I am, in general, very wary of any reports or articles that attempt to map results in mice to human behaviour and reports of the gut microbiomes driving autism / Alzheimer's / fear / what have you. This report combines both, so it gets extra red flags, IMO. Just my 2 cents.. not saying this isn't possible, but the bar for assuming this is true is very very high. And the results in the paper are a small first step in a very very long process required to substantiate this hypothesis.
