Twenty-six healthy participants, between the ages of 22 and 62, were enrolled in a double-blinded, randomized, placebo-controlled clinical trial to measure the effects of methylene blue on the human brain during working-memory and sustained-attention tasks. This study was approved by the local ethical committee
The participants underwent functional MRI (fMRI) before and one hour after low-dose methylene blue or placebo administration to evaluate the potential effects of methylene blue on cerebrovascular reactivity during tasks. Mean cerebral blood flow was measured pre- and post-intervention.
The results showed methylene blue increased response in the bilateral insular cortex--an area deep within the brain associated with emotional responses--during a task that measured reaction time to a visual stimulus. The fMRI results also showed an increased response during short-term memory tasks involving the brain's prefrontal cortex, which controls processing of memories, the parietal lobe, primarily associated with the processing of sensory information, and the occipital cortex, the visual processing center of the brain. In addition, methylene blue was associated with a 7 percent increase in correct responses during memory retrieval.
The findings suggest that methylene blue can regulate certain brain networks related to sustained attention and short-term memory after a single oral low dose.
A single oral dose of methylene blue results in an increased MRI-based response in brain areas that control short-term memory and attention, according to a new study. Methylene blue was associated with a 7 percent increase in correct responses during memory retrieval.

Actually it is possible that a chemical like this to could be presented in Earth Ecosystem, at some point in time in the future, much like Fluoride was included in the water system.
