Probiotics are not only good for your gut, but for brain also. Researchers from UCLA’s Geffen School of medicine have determined that consuming a milk fermented with probiotics changes the brain activity of women. The researchers divided 36 healthy women into three groups. One group was given a milk fermented with probiotics twice a day. Another group was given a milk without the probiotics. The last group was given no milk product. Before study began the women underwent extensive MRI studies and brain activity tasking response analyses. The researchers also utilized analyses that test emotional response. Then the women consumed the probiotic or placebo milk for four weeks, followed by repeated testing. After the four weeks, those women who drank the probiotic milk had significantly different brain activity changes. Their task-related responses increased, and their activity within the sensory cortex regions changed. Their midbrain connectivity increased, which the researchers concluded probably explained their task-related response increases. Their altered brain activity also illustraited changes in the brain signaling pathways for emotional responses among the women. Research has also connected the gut’s probiotics to the brain via a conduit between the central nervous system and the enteric nervous system, located  in the abdominal region around the digestive tract. Many of neurotransmitters are produced in this region and the neurons relay mind-body responses  between the gut and the brain stem.
