Left-Handed Women’s Brains Could Have A Special Ability

That is apart from their complete naturally-born awesomeness, of course, don’t you agree?


For years and years, we have seen that conventional science has shown us that there are parts of our brain that are responsible for processing smells.

We call them olfactory bulbs, and our brain processes signal from the nose and then sends them to other parts of the brain, where they’re further processed. It was generally believed that people who didn’t have these olfactory bulbs couldn’t smell, a condition called anosmia.

There has been a new study from Israel’s Weizmann Institute of Science, as it happens we can draw different conclusions about these links between olfactory bulbs and sense of smell.


But it turns out that there’s a tiny percentage of women who do not appear to have olfactory bulbs, however, they still have a normal sense of smell. It also happens to be that those women are all left-handed.

The co-author of the study, Professor Noam Sobel, is putting that “conventional science” into question. He said:

“I’m not sure that our textbook view of how the [olfactory] system works is right”

The phenomenon was discovered like some things are, by accident. The study was originally done to examine the link between the sense of smell and reproduction, utilizing brain MRIs. In with the participants, there was one who didn’t appear to have any olfactory bulbs: a 29-year-old, left-handed woman…


They, of course, asked her if she could smell, and she said yes! They conducted further tests too, and as it happens she actually has a better sense of smell than the average person, wow!

They did another study with another similar control group and again found the anomaly in another woman, so this repeatable result was promising evidence.

From this point, they looked at MRI results of 1,113 people who were said to have a really strong sense of smell, it showed three of them had no visible olfactory bulbs, and they were all women, and one of them was left-handed.

Sobel said: “It started to look like no coincidence”


All said and done, the researchers drew the conclusion that if you’re female and a lefthanded, you have about a 4 percent chance of still having a normal sense of smell, even though you have no olfactory bulbs.

Sobel said:

“We don’t know how to explain how these women can smell, why it’s primarily women or why it’s more pronounced in left-handed individuals”

One explanation could be that the brain is more adaptable than we thought, so, for people with this condition, then it’s can be the case, that it makes up for the absence of olfactory bulbs in other parts of the brain.

Maybe left-handed women’s brains are just wired up differently.

Maybe, even, the link between olfactory bulbs and sense of smell was not as definite as we thought it could be, and that we should really study whether olfactory capabilities could be found in other places in the brain?

Sobel tells us that the next steps are to focus just on left-handed women, and in a much larger-scale study to work out how many of these women can still smell even with an absence of olfactory capabilities.

Amazing right? Are you left-handed and want to share your thoughts about it? Or right-handed and think its all too much conjecture? Please do tell us in the comments below!
