The differences in connectivity between the periaqueductal grey and the cortex are interesting. The periaqueductal grey is a key nucleus in the pain pathways.

The probiotics group shows an increased connectivity with the prefrontal cortex, wich suggests an improved ability to control and reduce pain perception. The rest of the description is too vague for me to interpret.
