Last week I posted a link to an interesting article about how olfactory receptors are not just in our noses, as previously thought, but can actually be found throughout our bodies. Scientists have discovered that there is the potential for healing damaged skin and tissue with the application of various aromachemicals to damaged areas. You can read more about these discoveries and find the link to the article via my How Smell Works: It’s Not All in the Nose blog post.

This week, another interesting article made headlines around the world, again demonstrating the powerful healing potential of olfactory cells in the human body. In this case, cells taken from the olfactory bulbs in the brain of Darek Fidyka, a 38-year-old Bulgarian man, were used to heal his severed spinal cord. Darek has now learnt to walk again and can drive a car. You can read more about this incredible finding in this ABC News article.  If you want to read a little more about the method scientists used in the procedure, this article from The Guardian contains some good information.

Here is a short extract from the ABC News article:

The breakthrough came after four decades of research by Professor Geoff Raisman, from the University College London, who spotted the potential of cells that repair damage to nasal nerves.

The circuitry that gives rise to the sense of smell is the only part of the nervous system that constantly regenerates.

“The idea was to take something from an area where the nervous system can repair itself, and does throughout life, and put it into an area that doesn’t repair itself,” Professor Raisman said.

“I believe this is the moment when paralysis can be reversed.”

Amazing stuff! Enjoy reading and let me know what you think in the comments section below.
