The olfactory pathway, where neurons transmit sensory information to the brain, is another potential route for MPs to reach brain tissue. Further research is essential to understand how MPs reach ...

A new study suggests that stem cells thought to be dormant may offer clues to why our sense of smell declines or is lost.

The new findings raise concerns among researchers that the olfactory pathway might allow microplastics to access the brain and potentially reach brain areas beyond the olfactory bulb.

The findings suggest the olfactory pathway is a potential entry route for microplastics into the brain, Amato-Lourenco noted. "This is the first study to detect and characterize microplastics in ...

Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond the olfactory bulb. “Previous studies in humans and animals have shown ...

The new study revealed that there was “a potential pathway for the translocation of microplastic to the brain” via the olfactory bulb, raising concerns about their potential role in ...

By having patients sniff odor labels, identify scents and recall what they’d previously smelled, researchers are “hijacking the olfactory pathway, which has direct access to some of the first ...

The olfactory pathway may be a potential entry route for microplastics into the brain. Microplastics were found in the olfactory bulbs of eight of 15 human brains at autopsy, a case series showed.
