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.

Could Lamorna Ash become a Christian in a year?

Moving, funny and beautifully written, this young writer’s quest for faith has lessons for all of us.
A woman stares away from the camera
Lamorna Ash.

When two of Lamorna Ash’s university friends decided to leave behind their lives as standup comedians and train to become priests, Ash was fascinated. She interviewed them and wrote an essay about it for the Guardian but, by the time her piece came out, knew she was “not finished with Christianity.” 

“Perhaps it was naive not to have anticipated how spending my days alongside two fresh converts… would have some cumulative effect on me,” she writes. “Through these encounters, it was as if the very corner of the sky had been pulled back. I couldn’t see what was going on behind it, but I understood it was there for them… they taught me how to believe in the belief of others… their stories became the starting point.”  

And so Ash bought a second hand Toyota Corolla, stocked the glove box with CDs and set off on a Christian road-trip around the country that started with a Christianity Explored course and ended with a series of meetings with people who were consciously ‘dechurching’, taking in Catholics, Orthodox Christians, Quakers, Anabaptists and a YWAM community along the way. She books in ‘desert times’ on Iona; in Walsingham; at a silent Jesuit retreat. She walks, and talks, and tries to pray and thinks. Throughout her travels, Ash carried a ‘jokey’ question in the back of her mind to frame her research: could she become a Christian in a year? 

The result of her quest is this book: tender, fascinating, moving, funny and beautifully written. Throughout my reading of Don’t Forget We’re Here Forever I kept thinking of people I would like to give it to, Christian and non-Christian alike. Ash has achieved a remarkable feat: to make faith and its pursuit a compelling subject regardless of whether you’re a believer or not.  

Primarily, this is because she has not - joke question aside - set out with an agenda, other than to more fully understand what makes believers tick (and, she admits, because it is something to write about). Though she is scathing about Rico Tice, whom she finds performative and evasive, and finds the dogma of the Christianity Explored course too rigid and inflexible for her liking, she is sympathetic towards and interested in her fellow Christianity Explored small group companions - and is self-aware enough to admit that during this time she “played the worst version of myself: hackles raised, on alert, unable to let a conversation pass without some interjection”. Though she finds the intensity of Youth With A Mission’s community - along with the fact that many of the staff are married to each other - a bit much, she is individually drawn to some of the people who work there, and reflective about what and why they’re doing. As someone who has grown up with faith, it is fascinating to see what we often take for granted held up to scrutiny by someone who is not there to be deliberately combative, but to try and understand.  

“I am still too close to it to tell you definitively all the ways the encounters… changed me,” Ash writes. “What it felt like at the time, though, was that each conversation was leading me to places in my own mind I had never visited before.”  

There are elements of Ash’s book I am intrigued by, but sceptical of: her suggestion, for example, that the Bible should not stop where it does, but might be continually added to, “like a divine Wikipedia, updated in perpetuity.” Her theological understanding is not, perhaps understandably, advanced. She is a self-confessed product of her era: young, progressive, queer, and her readings of and understandings of other people are framed through that lens.  

But despite its failings, Don’t Forget We’re Here Forever remains compelling because of its curiosity - a curiosity that Ash wonders might be the place “where God exists”; its attempts, however stumbling, to understand faith rather than just dismiss it. It is an atheist Quaker who teaches Ash “how I might approach Christianity: it was supposed to be a challenge.” You will have to read it to learn where Ash herself ends up, but her book extends the challenge to those of us who might benefit from a similar scrutiny of what we believe - not to fall out of faith, but also to understand it, and God, more.
