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.

The Oscars and ourselves

Beyond the shiny escapism, the awards spotlight all our stories.

The Oscars are a funny old thing, aren’t they? Every year, I find myself wondering why we care about them so much.

And sure, we could go for the low-hanging answers: because the show is brimming with glamour, because it’s packed with celebrity, because we may be treated to Ryan Gosling performing his Barbie anthem with Slash. We’ve been trained to gravitate toward such things, and that makes the Oscars the jackpot. And so, while shiny escapism is an undeniable aspect of the enormous hype attached to the Academy Awards, I think it would be unfair to assume that these are the only reasons we are still so drawn to this event.

If we’re meaning-making creatures, and I believe that we are, then these films mean something.

I once heard renowned mythologist, Dr Martin Shaw, say that ‘story is the best way to talk about almost anything’, and I wonder if cinema is evidence of how heartily we agree. The stories that are being crafted and told are important, they matter, they actually affect things. Or, at least, the good ones do.

And this year, when I assess the films that swept up the majority of the prizes at the 96th Academy Awards, I noticed a trend. I noticed that these films are essentially humans talking to humans about what it means to be human.

In many ways, for better or for worse, we spent 2023 telling stories about ourselves. Allow me to break down what I mean.

These movies tell us of our own brokenness, our own breaking-things-ness.

Oppenheimer, which won six awards, and Zone of Interest, which was the first British film to win the Oscar for Best International Film – they tell our darkest stories. We know the 20th Century horrors of the dropping of the atomic bomb and the Holocaust, but these two movies introduce us to the faces behind the horror. And, what’s more, they hauntingly remind us that those faces could have been ours. They introduce us, not to monsters that we can keep at a comfortable distance, but to people who sanction, create and do the unimaginable, and then go home for dinner with their children.

People did these things. People like us. These movies tell us of our own brokenness, our own breaking-things-ness. They remind us that the possibility of evil is not beyond us, it is within us, and that the most dangerous thing one could do is to believe otherwise.

But then there was the acutely tender The Holdovers, and the deeply profound Past Lives. These movies tell of our gentleness, our fragility, our innate need for intimacy; they remind us that we were designed to be known and loved. They reintroduce us to our deepest and most innate needs - The Holdovers, in particular, tells us of the sacrality of relationship. Its success has me wondering if a story of three lonely people forced to spend Christmas together in an empty boarding school could tell us more about what our souls require than any academic deep dive.

Yet again, these films seek to tell you the story of you; they aim to be windows into the souls of the characters, while also acting as mirrors through which we can catch glimpses of our own.

Each movie, in one way or another, was a wrestle with personhood. What makes us, us?

And finally, there were two films, Barbie and Poor Things, which, to criminally over-simplify them, are the stories of two women (or, rather, one toy and one new-born baby in the body of a grown woman… don’t ask) who are working out what it means to be a person. Both Barbie and Bella Baxter walk through worlds that are entirely new to them, but completely familiar to their audiences. They assess the good and the bad of humanity as if utterly detached from it, until they are forced to confront their own place in the worlds that they are slowly coming to terms with. As is written into the script of Poor Things and was read aloud over a montage at the Oscars ceremony,

‘We must experience everything. Not just the good, but degradation, horror, sadness. This makes us whole Bella, makes us people of substance. Not flighty, untouched children. Then we can know the world.’

(Is it me, or is there a little touch of – ‘just take a bite of the apple, Eve’ in there?)

So, you see my point – this year, in the world of film, humans talked to other humans about what it means to be human. Each movie, in one way or another, was a wrestle with personhood. What makes us, us? Where does our propensity for goodness come from? How are we this clever? And how are we this clueless? Why do we do such evil things? And why do we have such tender needs? What is the difference between the worst and the best that we could possibly be? What and why are we? Or, in the simple words of Billie Eilish’s Oscar-scooping song – what were we made for?

And listen, perhaps this is always somewhat the case. Maybe every film can be boiled down this way, and maybe the Oscars are just a storm in a particularly glitzy tea cup. And maybe nobody would be talking about it this morning had Slash not been involved.

But I just have this sense that these movies, and the prizes that they won, mean something. These existential-yearning kind of films, I’m not sure they’re going anywhere anytime soon – if we’re wondering what we were made for in such public places, I’m wondering if it’s because we’re also wondering the same thing in the most personal places.

If you’re asking me, last night was filled with as many cultural heart-cries as it was prizes.
