One of the more exciting aspects of microbiome research is how gut microbes can have an impact on neurological events. One recent example is a study from investigators at the University of Missouri (MU) School of Medicine, and MU Health Care who found that obstructive sleep apnea (OSA) related sleep disturbances affect the gut microbiome in mice and how transplanting those gut bacteria into other mice can cause changes to sleep patterns in the recipient mice.
