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 falcon’s call

Awed by an encounter with a bird of prey high above a Texas river, Anthony Baker ponders both the place and his place.

Seeing God in Big Bend

The scream from the sky shattered the quiet calm of my cliffside campsite. I'd never heard such a sound—it was like a large crow had decided to try and quack. I rushed out of my tent, where I'd collapsed after making the seven mile trek up the mountain, to find the source of this alarming noise.

I was up on the rim of Big Bend National Park in southwestern Texas, where I'd come on a solitary backpacking retreat. The "big bend" is the abrupt L-turn of the Rio Grande river, as it changes course from southeast to northeast. At the heart of the park rise the stark and severe Chisos Mountains, and the crown jewel of the Chisos is surely the South Rim. A thousand feet beneath me, a sheer drop from where I've staked my tent, there is a whole other mountain range. And ten miles away to the southeast I could see gorgeously striped limestone ridges across the river in northern Mexico.

It's a place that puts you in the presence of the sublime.  Everett Townsend, the pathfinder responsible for bringing the region under the protection of Franklin Roosevelt's government, was particularly awed by this view. As a biographer put it, the view from the South Rim allowed him to

"see God as he had never seen Him before and so overpoweringly impressed him that he made note of its awesomeness…"

What does it mean, though, to see God in a place? Do I need to be up high and far away, staring into sublime depths? The South Rim gives me the impression that I'm hovering like an eagle over the earth, not standing on it like a human. Why are these the places that we think we sense the divine? 

I'd like to think that seeing God in a place can be just as much about close and near attention as it is about sublime distances. What does God look and sound like here, if I stand on the ground and pay as much attention as I can to what I see and hear around me?

The Falcon's cry

I had no Internet connection on the Rim, so when I heard that bird cry out over my head I tried to burn the sound into a mental audio file. Jumping from my tent, I saw a large predator bird shooting directly above me and out over the cliff's edge. The size and shape—a large flying crossbow—told me that I'd been hailed by a peregrine falcon. A sign near my site told me that the section of the ledge where I was camping—where the South and East Rims meet—is in fact a protected nesting ground for the birds, closing to human trekkers each spring.

The peregrine is the world's fastest animal of any kind. They can dive at 200 miles per hour. That means they can only hunt birds in flight, since if they attacked anything on the ground at that speed they would both wind up, as my Granny would put it, "nothing but a greasy spot on the pavement."

A display down at the park's visitors' center had already filled me in on the near demise of the remarkable bird. DDT, a killing-machine of a pesticide that Rachel Carson called out in her book The Silent Spring in the 60s, triggers an immuno-response in female birds who have ingested it into their bodies. This response limits the calcium they can supply to their eggshells. As a result, the eggs were too vulnerable to predators or simply weather, and the embryos were not surviving.

We gave the Nobel Prize to the scientist who discovered how to use DDT to kill insects. It made so much sense, after World War II, to find ways to kill the pests who were spreading disease among the wounded soldiers and other victims of the war. But we were not yet thinking, in those days, about what else we might be killing. Now we're at least thinking, even while we're still killing.

Sin and redemption on the mountain 

What does the falcon, soaring off the Rim, reveal to me about God? Consider, for instance, the doctrine of sin. Taken as an abstraction, sin is what theologians call the manifold ways that humans can turn from their holy God.  But what if we fill that doctrine in with attentiveness to the story the falcon tells us? Here on the Rim, sin looks like failing to be awed enough by this remarkable life form to notice, until almost too late, that we are killing it. 

Similarly, redemption, in the Christian telling of things, refers to the way that God overcomes sin and restores holy relationship. Here on the rim, redemption looks like a shared grief over the damage we've done. It looks also like the effort to protect this space as a bird sanctuary—literally a "holy place." It looks like a hope that falcon and human, like the bird and its own prey, can find a balance of mutual respect and coexistence.

The warning call of God

When I came down the mountain, I got on the Wi-Fi at the lodge outside the park and went searching for bird calls. I found a match for the sound that I'd heard - that caw-quack of a scream. It was the warning call of a peregrine falcon who has found predators in its nesting grounds. The bird was talking about me! Maybe somewhere in her DNA she recognized me as one of the DDT users that ruined her ancestors' eggshells. Hearing that call, as the bird flew off into sublime depths and distances, I suspect I was hearing about the mystery of life, the damage of sin, and the beauty of redemption. In other words, I was hearing the voice of God.
