Neuroplasticity


This story keeps getting crazier the further you read. 

Woman with no left temporal lobe developed a language network in the right side of her brain
Apr 2022, phys.org

A woman without a left temporal lobe developed a language network in the right side of her brain that allowed her to communicate normally. She only came to realize she had an unusual brain by accident—her brain was scanned in 1987 for an unrelated reason. 

By all accounts she behaved normally, earning an advanced degree and excelling in languages—she speaks fluent Russian—which is all the more surprising considering the left temporal lobe is the part of the brain most often associated with language processing.

It was likely the woman had lost her left temporal lobe as a child, probably due to a stroke. The area where it had been had become filled with cerebrospinal fluid. To compensate, her brain had developed a language network in the right side of her brain that allowed her to communicate normally.

She also had a sister who was missing her right temporal lobe, and who also had no symptoms of brain dysfunction—an indication, the researchers suggest, that there is a genetic component to the stroke and recovery process in the two women.

The Renaissance of Smell



Immerse yourself in a pot of hot enfleurage so we can bottle your essence forever, just like this murder victim from the movie Perfume.

Trends come and go, we know that. The rate of change, however, is a topic worthy of discussion. People used to say that fashion revolves on a twenty year cycle – wait til the 90’s and bellbottoms are cool again. You know what hasn’t been in fashion for a while though? Smell.

I’m looking at a great piece by Smell Futurist Olivia Jezler about the coming wave of olfactory experience headed our way. It was written a year ago, but since we’re going to examine very long timescales here, her piece is still relevant. This is a slow wave.

Looking Back – The Loss of a Sense
Unlike bellbottoms and banjos, smell is not a cultural artifact; it is a medium for transmission. And as such, it’s been around forever. Longer even than the comb-over! And it used to be so important to us. It told us what was ok to eat, who was ok to mate with, and when to take out the garbage. And then, one day, tricolor vision and bipedal height advantage come along, and BAM – no more smells.

Seeing in color makes eyes the most high-fidelity info channel ever, and the height advantage from walking on two legs both expands that field of polychromatic vision and takes our noses off the ground, making them way less useful. Vision wins, and olfaction bites the dust. We spend the next half a million years looking at flowers and listening to crinkly sounds but not a single smell. Sure there’s food and taste, but we have very completely convinced ourselves that most of what we taste is taste and not smell, although it is in fact the other way around.

(Also dogs – I don’t hear many people saying this, but I think human coevolution with dogs, who can smell really well, made us not have to smell as well. Animal cognition expert Alexandra Horowitz might be able to weigh-in on this.)

There was a brief moment around the late 1700’s when smells took the spotlight again, causing the French Revolution and subsequently pouring the foundation for our modern public hygiene infrastructure, not a big deal. And that’s it. No more smells, anywhere.

Looking Forward – The Experience Economy
And then, all of the sudden, we enter the new millennium and it becomes apparent that smell has returned. One day we wake up and flowers smell floral, and perfume bottles no longer spray odorless distilled water (but fatal nerve agents, not funny). Things will get way crazier, according to Jezler’s insights.

“The Renaissance of Smell“
-Bernardo Fleming, Head of the Olfactive Design Studio at International Flavors & Fragrances

Jezler points out what has happened to cause this disturbance in our datasphere – people are now willing to pay more for experiences than for things. I call this dematerialization, but she goes on to describe the cycle of consumerism upon us. She describes how brands today put lots of money behind the creation of experiences that cannot be ‘consumed’ unless you’re there for real.

I think she would have to explain to me why it is that brands want their consumers to go somewhere and do something together. Something about memetic transmission and social networks I guess. Or how about exclusivity? I’ll bet that’s it. You’re just jealous because you’re only hearing about this now, after it’s already been transmitted by someone cooler than you, and that makes you want it more.

An experience economy needs to use all the senses, and this has put more attention on the low hanging fruit, the most unexplored on the market – smell.

And although you can partially consume last night’s pop-up event via this morning’s newsfeed, you can never get the whole thing, because you will never smell it if you’re not there. And that’s because the event last night was augmented by a group of olfactory magicians on the team. From the smell on the seatbelts in the cab on the way over, to the scent on the ticket they gave you at the door, that event was designed as a fully immersive olfactory experience, whether you realized it or not.

Talk about Joel Beckerman and sonic branding – it’s more powerful than Pavlov. (Just kidding it’s the same.) You hear a jingle over and over until it brands a band of your auditory cortex. You’ve been primed.

Scent branding works too, although we pay attention to it less. Whether we notice or not, the brands notice; take a look at Play-Doh exercising their intellectual property rights to be a specifically-scented product. But I am digressing from the point. The Renaissance of Smell rides not just the wave of the experience economy, but also of the palette-forward generation behind the wheel.

“…Smell has been put back on the map through a myriad of factors, and three reasons I believe in particular: Our desire for experience, academic progress, and the rise of the gourmet palette.”
-Olivia Jezler, Owner of The Future of Smell, Fragrance Innovation Consultant

Consumers of today know way more about their biscuits than their grandparents did. Just look at what’s written above a café counter today vs thirty years ago. (It used to just say “Coffee.”)

Just Coffee

This sophistication extends far beyond coffee, and it gives consumers the talent, the exposure and the lexicon to appreciate the gustatory satisfaction of complex aroma.

Looking For Reinforcements – Academia Adds Potency
I saved the “academics” part of Jezler’s premonition for last. The experience economy, of which the gourmet movement is a part, is not the only thing fanning a more fragrant datasphere towards our sensory apparatus. Jezler uses the Academics tag to group together all the new technologies and concepts that have augmented and extended our understanding of this most primitive of senses, from digital noses to hormonal engineering.

Unfortunately, I’m a real pessimist about anything even slightly resembling an electronic nose, or the digital transmission of odorous molecules. However, when I hear somebody (the MIT Media Lab) say that estrogen is a “biotechnical civil disobedience, seeking to subvert dominant biopolitical agents of hormonal management, knowledge production, and anthropogenic toxicity,” I can’t help but get pretty excited. (They’re connecting the profusion of environmental estrogen due to excess petrochemical use, or ‘xenoestrogen,’  to an increasing hormonal malleability, or ‘queering’ of our society, in case you’re wondering.) 

There are plenty of legitimate attempts at bringing our noses to the technocratic party, but I don’t see these going beyond fiction for quite some time. In fact, I should say that it is the main reason why it is such an intriguing subject for a fictional future.

But in the end, it doesn’t matter if it’s fact or fiction (especially in today’s world where Big Data has made the truth way harder to faithfully articulate). After all, science fiction gives us the imagination that we need to create the future.

Despite the threat of our world becoming a cold, body-less, virtual space that is a network of quantum repeaters in low earth orbit, Jezler sees us re-engaging with all of our senses. Chances are it will be a bit of both. In the meantime, it makes good business sense to consider the low-hanging fruit of the experience economy. Whether you’re designing the next delivery bot, or writing a proposal for research funding, don’t forget that people care about their sense of smell. It’s what makes an experience authentic, and authenticity will always be in style.

Age of Approximation

Screenshot from Iain McGilchrist called the Divided Brain on RSA Animate and TED.

“The Age of Enlightenment is Dead.” Thank you, Mr. Danny Hillis, for putting this in writing, and in the new MIT Journal of Design and Science no less.

Mr. Hillis makes the case, in a brief but very coherent treatise, that science is due for an update. In fact, it is not just science, but the very idea of human endeavor and progress. I recall the TED talk given by Iain McGilchrist called the Divided Brain. (This guy is author of The Master and His Emissary: The Divided Brain and the Making of the Western World, 2009). In his talk, he describes how the brain is split in two; the truth is more nuanced than that, and this is the point of the talk in fact. He goes on – there are two metaphorical sides, and they each do two different things, and the reason we tend to be right-handed is because the corresponding side of our brain is for active, intentional manipulation. And on – throughout history the pendulum swings, and one day we may regard the right side as the “right” side (because the Age of Enlightenment made us value the left side so much).

In the art classroom, I repeat these ideas, and ask them what the world would be like if everyone was “right-brained,” or artistically minded. Imagine if everyone was an artist, and nobody a scientist, all emotion and flight-of-fancy, and no bridges, tunnels, infrastructure, economic policy, institutions of higher learning, no numbers, no logic, and nothing to separate sense from nonsense. Crazy.

Then again, I can sort of imagine a world where artificial intelligence does all that stuff for us, so we can do more human things, more messy, emotional, intuitive things. I highly doubt this is what Mr. Hillis is talking about in his essay, but I’m quite excited nonetheless that he’s talking, period. He says right here:

“As our technological and institutional creations have become more complex, our relationship to them has changed. We now relate to them as we once related to nature. Instead of being masters of our creations, we have learned to bargain with them, cajoling and guiding them in the general direction of our goals. We have built our own jungle, and it has a life of its own.”

Danny Hillis, MIT Journal of Design and Science, March 2016

Post Script:
What the hell does all this have to do with the Language of Smell?

A primary objective of Hidden Scents is to present the idea that after the wave of Big Data crashes on the shores of human civilization we will have entered a new era, one in which certainty itself is no longer valued in the way it once was. We already see this today, when we ask what it is that separates us from our imminent AI overlords. Humans have intuition, something an algorithm can never have, by its nature. Humans can do this thing called “messy thinking,” or fuzzy thinking, or half-thinking. This is what leads us to make novel discoveries and connections and to be creative in general. This is what makes us not computers. And in its uncanny way, this kind of mental activity is at the core of olfaction. To smell something is to navigate a sea of data too large to fully comprehend. In this sea, one can approximate, but never ascertain. (The source of a particular smell is only verified by one of the other senses, like when you actually find that dead mouse under the fridge.)

So if the Age of the Enlightenment is dead, then perhaps olfaction (and more specifically the language of olfaction) can serve to carve the path ahead.

Well, perhaps you think I’m a bit too right-brained to be writing about such things. Thanks for reading at least.
