Previous data in animals and humans have shown the potential of manipulating the gut microbiome to modify emotional and cognitive depressioneskala and brain function.

For instance, Bifidobacterium longum has been tested for central effects in mice and humansbut studies assessing how probiotics may affect behavior and brain function in healthy volunteers are scarce. A new double-blind, placebo-controlled randomized studyled by Dr. Participants were divided equally into three groups: Functional magnetic resonance imaging fMRI was used to measure changes in emotion-related brain activation patterns. Stool samples were collected to investigate the gut microbial composition before and after the probiotic intervention.

Probiotic administration for 4 weeks improved self-reported behavioral measures ad positive affect in terms of hopelessness and risk aversion and cognitive reactivityas measured with four self-reported depression and adw questionnaires, namely, Positive and negative affect schedule PANASSymptoms checklist SCLAllgemeine Depressionsskala ADSand Leiden index of depression severity LEIDS.

Probiotic administration was also associated with changes in brain activation patterns in response to emotional memory and emotional decision-making tasks. Besides this, blood oxygenation level signal changes in fMRI emotion recognition tasks correlated with self-reported behavioral measures in the probiotic group. Probiotic participants changed their decision about the selection of the most unpleasant stimuli less frequently than the control subjects during the emotional decision task.

Furthermore, the influence of the probiotic on decision-making processes was reported by changes in neural activity in the cingulum and precuneus in the emotional decision task. These results show that probiotic-induced changes in self-reported measures of emotional behavior can be confirmed by measuring neural correlates of emotional decision-making and emotional memory processes.

On the other hand, changes in emotion-related brain activation patterns were also accompanied by subtle but significant shifts in the gut microbiota composition. In this regard, two operational taxonomic units belonging to Bacteroides sp. Finally, a relationship was found between gut microbial composition, blood oxygenation level signal changes in the cingulum and cerebellum and behavioral measures.

Due to the involvement of cingulum and cerebellum in decision-making and emotional processing, these results suggest that probiotic effects on behavior are reflected in imaging measures.

Furthermore, microbial composition was associated with self-reported behavioral measures. Specifically, the scores from the depression questionnaire ADS were associated with a higher abundance of metabolic pathways involved in starch and sucrose metabolism. In conclusion, these data show the distinct probiotic influence at behavioral, neural and microbiome levels in healthy volunteers. These results are in line with a well-known study led by Professor Emeran Mayer, which showed how administration of a fermented milk product with a probiotic for 4 weeks affected the activity of brain regions involved in controlling the central processing of emotion and sensation; they are also in line with a study from McMaster University.

Probiotics drive gut microbiome triggering emotional brain signatures. Although the allgeemine gut microbiome is a source of antibiotic resistance genes ARGsuntil Paul Enck, Director of Research, Dept.

His main interests are gut functions in health and disease, including functional and inflammatory bowel disorders, the role of the gut microbiota, regulation of eating and food intake and its disorders, of nausea, vomiting and motion sickness, and the psychophysiology and neurobiology of the placebo response, with specific emphasis on age and gender contributions.

He has published more than original data paper in scientific, peer-reviewed journals, and more than book chapters and review articles. An update on the microbiome and allergic diseases. The most significant achievements in gut microbiome science in Scientists characterize antibiotic resistance genes in metagenomic data based on the 3D structure of the proteins they encode.
