“Hundreds of species of bacteria call the human gut their home. This gut “microbiome” influences our physiology and health in ways that scientists are only beginning to understand. Now, a new study suggests that gut bacteria can even mess with the mind, altering brain chemistry and changing mood and behavior.”
The indications are mounting that, like other things we dump in our gut, bacteria can also affect our mind. The conclusive evidence here is that the effect seen on mice fed with a certain bacteria goes away if the vagus nerve (a nerve that transmits info from gut to brain) is severed prior to feeding the bacteria to the mice. Just wondering when the probiotic mood-altering pills and yogurts start coming out. Or better, LSD synthbio bugs escape and we all go for a trip!
