The impact of low-level carbon monoxide on cognition and brain activation

“The findings of this research suggest that exposure to a relatively low amount of CO (raising exhaled CO levels by only 3ppm) was sufficient to cause not only changes in brain activation, but also in cognitive task performance…This does pose the question of how ambient CO pollution may be affecting our neurovascular health…”
