Finding two women without olfactory bulbs, but with a sense of smell seemed like too much of a coincidence, so the team did a deep dive into the data, analyzing MRI brain scans from the Human ...

A brain scan of a person with olfactory bulbs (box A) looks very different than brain scans of people without olfactory bulbs (Boxes B, C and D). (Image credit: Weiss et al.) ...

The tiny scraps of plastic were found in the olfactory bulb, the part of the brain responsible for processing smell. IE 11 is not supported. For an optimal experience visit our site on another ...

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.

Until now, it has been commonly accepted that our sense of smell depends on the transmission of olfactory information from the nose to the olfactory bulb in the brain. Therefore, without olfactory ...

Researchers at the National Institute of Neurological Disorders and Stroke (NINDS), a part of the National Institutes of Health, have identified a specific, front-line defense that limits the ...

After MRIs, diffusion MRIs, ultra-high definition 3D imaging, and whole-brain voxel-based morphometry, they concluded that yes, all three of the women had no visible olfactory bulbs but otherwise ...

Sep. 29, 2022 — Since their discovery over 100 years ago, neurons in the brain's olfactory bulb, called tufted cells, have been difficult to study. By leveraging new technology, neuroscientists ...

In order to scan the olfactory bulb, the scanner was set at a resolution of 25 µm; for the brain, it was set at 100 µm. Chromogenic immunostaining was used to assess brain abnormalities found in ...

A recent study published in Current Biology has found that animals living at elevations of 1,000 meters and higher have a ...

Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb. The particles were likely breathed in ...
