THE IDEOLOGICAL BRAIN: The Radical Science of Flexible Thinking, by Leor Zmigrod Having a one-track mind can feel pretty good.

The nose, she knows, is loaded with bacteria, and they’re “really, really close” to the brain—mere millimeters from the olfactory bulb, which processes smell.

Eight out of the 15 brains studied had microplastics in their olfactory bulbs. However, these eight samples had only 16 microplastic particles between them, which is perhaps some comfort.

Study Overview The study examined the olfactory bulbs of fifteen deceased individuals, aged between 33 and 100, all of whom had resided in São Paulo for over five years.

A study published in JAMA Network Open confirmed that microplastics can be present in the olfactory bulbs of the brain in people, based on their analysis of 15 deceased people.
