Abstract

Background & aims Changes in gut microbiota have been reported to alter signaling mechanisms, emotional behavior, and visceral nociceptive reflexes in rodents. However, alteration of the intestinal microbiota with antibiotics or probiotics has not been shown to produce these changes in humans. We investigated whether consumption of a fermented milk product with probiotic (FMPP) for 4 weeks by healthy women altered brain intrinsic connectivity or responses to emotional attention tasks. Methods Healthy women with no gastrointestinal or psychiatric symptoms were randomly assigned to groups given FMPP (n = 12), a nonfermented milk product (n = 11, controls), or no intervention (n = 13) twice daily for 4 weeks. The FMPP contained Bifidobacterium animalis subsp Lactis, Streptococcus thermophiles, Lactobacillus bulgaricus, and Lactococcus lactis subsp Lactis. Participants underwent functional magnetic resonance imaging before and after the intervention to measure brain response to an emotional faces attention task and resting brain activity. Multivariate and region of interest analyses were performed. Results FMPP intake was associated with reduced task-related response of a distributed functional network (49% cross-block covariance; P = .004) containing affective, viscerosensory, and somatosensory cortices. Alterations in intrinsic activity of resting brain indicated that ingestion of FMPP was associated with changes in midbrain connectivity, which could explain the observed differences in activity during the task. Conclusions Four-week intake of an FMPP by healthy women affected activity of brain regions that control central processing of emotion and sensation.

  • Ingestion of a fermented milk drink combining four bacterial strains was associated with changes in resting brain activity and midbrain connectivity centered on the periaqueductal gray, plus other regions, in healthy women.

    “Alterations were observed in resting brain activity showing that ingestion of the fermented milk product was associated with changes in midbrain connectivity centered on the periaqueductal gray, along with other brain network regions including the prefrontal cortex (PFC), precuneus, basal ganglia, and the parahippocampal gyrus”

    The Abstract and the section on the PAG-seeded resting-state network report altered resting-brain connectivity in healthy women, including a PAG-centered network with prefrontal, basal-ganglia, and parahippocampal regions. But Study Products and Administration lists five bacterial strains, not four; the four names in the Abstract are bacterial groups, with two strains of L. bulgaricus. The Discussion associates the precuneus finding with task-related activity rather than specifically with resting-state connectivity. (LLM, conf=0.90)

  • Intake of a fermented milk product containing multiple probiotic strains reduces the neural response to faces showing negative affect in healthy women.

    “The initial study in this area demonstrated, in a sample of healthy women, that intake of a fermented milk product containing multiple probiotic strains could reduce the neural response to faces showing negative affect (fear or anger) (Tillisch et al., 2013).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
