Gut Bacteria Affect the Brain

Rambo Tribble writes "John Cryan, a researcher at the University College Cork, explains the relationship between the bacteria in your gut and your brain. 'In a pioneering study, a Japanese research team showed that mice raised without any gut bacteria had an exaggerated physical response to stress, releasing more hormone than mice that had a full complement of bacteria. However, this effect could be reduced in bacteria-free mice by repopulating their gut with Bifidobacterium infantis, one of the major symbiotic bacteria found in the gut. Cryan’s team built on this finding, showing that this effect could be reproduced even in healthy mice.' It seems the flora in your intestines can influence brain development as well as aspects of health and nutrition, which in turn affect such things as hormones and neurotransmitters. 'His team tested the effects of two strains of bacteria, finding that one improved cognition in mice. His team is now embarking on human trials, to see if healthy volunteers can have their cognitive abilities enhanced or modulated by tweaking the gut microbiome.'"

Machines

I don't think I mind being an extraordinary complex machine functioning to protect the interests of very simple organisms incapable of thinking for themselves. But that might just be my bacterial overlords talking.

I always knew humans were basically full of shit.

...the human genome is a monolithic kernel, and the bacteria are all the shell scripts and daemons that help manage it.

So what you're telling me is essentially that the viability of myself and any offspring is going to depend on a massive collection of perl scripts. Lovely. I'm forked. :(

My gut tells me you're onto something here.
