Study connects tongue bacteria to cognition
A recent study published in the journal "PLoS One" revealed statistical correlations between certain types of oral bacteria and the speed of information processing in humans. The results showed that higher levels of the bacteria *Prevotella histicola* are associated with faster responses in cognitive tests. The researchers attribute this to the role of these bacteria in converting nitrates into nitrites, which in turn contributes to the production of nitric oxide, improving blood flow to the brain. However, the scientists clarified that the study is exploratory and does not establish a direct causal relationship, noting that other factors such as age and diet also influence cognitive performance and oral health.
