Why smell jumps the queue when it comes to memories

Smells hardwire deep into the brain, writes Henna Cundill, as she explores why they jump-start such vivid memories.

When I was a 22-year-old undergraduate my mother died quite suddenly. I can't remember the name of the undertakers we used, nor the chaplain who took her funeral. I can no longer visualise what any of their faces looked like. I know I visited the chaplain’s house to plan the funeral, but I can't remember exactly where that house was. What sticks is that the day of the funeral was a sultry summer's day, and both the chaplain and the undertakers smelt of perspiration. To this day there are moments where I catch that same whiff of man-sweat in some other location, and for a fleeting second, I am a bewildered 22-year-old once more.

Here is another memory. I attended a tiny, rural Church of England primary school in the middle of England. At the end of each school year, all of us donned our little Wellington boots, which smelt faintly of slurry (since this was dairy-farming country) and sweaty feet. Then we lined up in a crocodile and trudged through the bluebell-wood (damp leaves) and skirted the edge of fields (silage, which stings the nose) covering the mile or so between our school building and the village church.

We would enter the church grounds through the back field, hurrying through an eerily muffled graveyard with tombstones towering far above our heads and the grass disturbingly lumpy beneath our little feet. To the chidings of “Quickly!” and “Quietly!” we children scurried down a gravel path, away from this unsettling place of death, to reach the cool sanctuary of a little church, and the comforting smells (for me, at least) of damp stone and dusty hymnbooks.

Others may not have the same associations, but for me the smell of dust and damp stone will always cry “safety!” and the reassurance that “there are no ghosts in here!” in contrast to that troubling graveyard. From death to life. Yet, at the same time, getting stuck with my nose close to some man’s whiffy armpit on the Tube will forever insinuate that I am just a child pretending to be a grown-up, out of my depth, overwhelmed with one thousand decisions to make (“What flowers do you want for her coffin?”) and no-one to advise. In the midst of life, death again.

On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances.

Of course, I am not 22 years old and lost anymore, no matter what that man’s armpit tries to tell me. My rational mind knows better, but my rational mind doesn’t get a say – or doesn’t get the first say anyway. This is because smell is the only one of our senses that bypasses the thalamus (the brain’s ‘filtering gate’ that decides which part of the brain needs to respond to sensory input) and goes straight to the limbic system, where emotional memory is stored.

Sometimes it is very obvious that this is taking place, such as in the examples given above. On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances. But it can happen in more subtle ways too. Supermarkets infamously pump out smells to influence our buying choices, and we’re trying to sell our house right now, so we’ve been brewing a whole lot more coffee than we ever usually would.

Intriguingly, scientists don’t really know why the human sense of smell jumps the queue when it comes to cognitive processing. There are biological theories, such as that the smell of predator could wake up our ancestors while they were sleeping and/or could allow them to follow a scent trail quickly when fleeing danger or seeking food. There are social theories too, such as that we don’t have a lot of good words to describe smells, so the brain just doesn’t bother trying to analyse them. Whatever the truth of the matter, the reality is that (whether we like it or not) our noses are an emotional trip-hazard.

When I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse.

I can’t help wondering what this tells me about my religious practice. Do I go to church because I have made a cognitive decision to worship God each Sunday? Or do I go to church because I am following my nose, getting away from a world full of armpits and responsibilities to a place where I am a seven-year-old girl, all gingham dress and wellies, feeling safe. If so, does it matter?

Truth is, my mind can give me a dozen reasons not to go to church every single week. In fact, two dozen reasons. More. It has always been a busy week; I’m always behind on work. The house always needs a sort out and the car is never washed. But because certain congregation members are normally counting on me for certain things, and because I’m still pretending to be a grown up, I typically drag myself out the door, and off to church I go.

And week on week, without fail, when I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. My body registers this before my mind; my shoulders drop a little of their tension. Even if it’s just for a fleeting moment, I start to feel that I know for sure what is absolutely real in my life and what is just pretend.

Is this knowledge irrational – since it doesn’t come from the cognitive part of my mind? Or is there a God who knows that the cognitive part of my mind sometimes tells me all sorts of untrue and unhelpful things. Is there a God who is choosing to reach out to me in more subtle, more ancient ways?

I can only wonder if I have been following my nose all this time, without even noticing. Drawn along by an ancient scent trail that leads me time and time again…this way…and that way…until I reach a place where there is safety, and bread.

What do we want from our stories?

New film release American Fiction satirises storytelling and the expectations placed on authors. Jamie Smith records his reactions to watching the movie.

On a recent visit to Los Angeles, my wife Deanna and I went to see Cord Jefferson’s new satire, American Fiction, playing in only seven theaters nationwide right now. The film is a smart, beguiling adaptation of Percival Everett’s novel, Erasure.

Part of the fun of watching movies in L.A. is being reminded what a company town LA still is. We were slightly puzzled when, as a production company splash screen opened the film, a ripple of hoots and applause bubbled up from the audience. When, at the end of the movie, we saw an entire group video-recording the rolling credits, we realized a production team was in the house, seeing their work on the public screen.

Watching this particular movie in L.A. was especially entertaining because of its meta commentary on our storytelling industries, including film. The winks & nods about screenwriting, adaptation, and philistine studio executives occasioned knowing guffaws in the audience.

The movie asks important, uncomfortable questions about the stories that “we” (scare quotes will become obvious in a second) want to hear today, and why.

What’s supposed to be a farce is embraced by white marketing executives as the latest Black trauma porn for awards season.

The key facet of the plot is relatively simple: a Black novelist (Thelonious “Monk” Ellison, played cagily by Jeffrey Wright) has published several works of deft, critically-celebrated literary fiction. But he can’t sell his latest novel. His agent informs him why: “It’s not Black enough.” The Black novelist is puzzled (“But I’m Black!”) until he wanders into a reading from a new bestseller, the latest by a Black novelist celebrated by some famous white woman’s Book Club. Written in dialect, with flat characters and tired tropes, the novel panders to and perpetrates horrendous stereotypes dusted with a hint of redemption. But it does so with just the right dose of guilt-induction for white readers to feel morally assuaged just by reading the book. The publishing industry has seized upon the mad, pretzeled formula: You can sell a lot of books to white people by offering them the thrill of a little enlightened guilt that actually depends on their continued racist stereotypes.

In a fit of disgust, rage, and desperation, “Monk” begins banging out just such a novel, determined to play a kind of Sokal-hoax on the publishing industry. Just one problem: the market clamors to buy this dreck and even turn it into a movie. What’s supposed to be a farce is embraced by white marketing executives as the latest Black trauma porn for awards season. You can imagine the comedic possibilities here. It’s a funny movie.

As a white viewer of this movie, if I laugh at all the right points and get all the inside jokes, am I being offered a little absolution?

But it is also tender. What’s playing out on screen—the story surrounding the creation of the novel’s story—is a very different kind of Black story. Monk, it turns out, is the black sheep only because he’s a PhD in a family of MDs. Here is a Black family with a massive Victorian home in Boston and a beach house on the Cape—which is just to say, they are a family of accomplished professionals like so many others. Are we surprised? Like any human family, of course, their life is not without pain, loss, heartbreak, and animosity. But like any human family, there is also achievement, pride, joy, connection.

Here’s a Black family. Here’s their story. Is this a “Black story?” Is it “Black enough?” What do we want from our stories?

Jefferson’s endeavor here is fraught, and he knows it. The last part of the movie “goes meta” as a way to concede that there’s no “clean” way to raise these questions without slipping back into being part of the problem. As a white viewer of this movie, if I laugh at all the right points and get all the inside jokes, am I being offered a little absolution? To his credit, Jefferson never quite lets a viewer like me off the hook. Something about this story will, and should, remain unavailable to me.

But also to his credit, Jefferson had me thinking of the Roman poet Terence when we walked out of the cinema. Homo sum: humani nihil a me alienum puto. “I am human: nothing human is alien to me.” Jefferson tells a story that, in this climate, is willing to risk a claim to human solidarity.
