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.

Summertime is well and truly here and with the UK currently sweltering under one of the driest years on record, you would be well advised to seek out indoor activities to occupy the hottest hours of the day. But what to do with this time? So many options jostle for our attention and, as Rachel Luckett recently reflected for Seen & Unseen, reading is losing out with the number of readers steadily dropping year on year. Luckett reminds us that what we read is as important as how much we read; recommendations which intrigue and stimulate us are essential and the best place to get such recommendations is stimulating conversation.  

Where do I find these conversations, I hear you ask. Well, look no further than the Re-enchanting podcast from Seen & Unseen with its perennial opening question: what are you reading? To kick start your holiday reading, here’s a round-up of our guests’ choices from season six of Re-Enchanting. 

In retrospect, our guests seem to have a pronounced inclination towards biography and memoir. Earlier this year, Re-enchanting welcomed the notable forensic scientist, Sue Black, onto the show to discuss her (scientific) fascination with all things living and dead. Despite, or perhaps because of, a life spent looking death in the face, Black begins our summer reading with Richard Holloway’s meditation on a fading life, Waiting for the Last Bus

Whilst Black’s distinct lack of squeamishness may be not be shared by all, her desire to piece together the lives and stories of those she meets seems to be a common thread linking many of our guests. Those contemplating a continental get-away might wish to search for inspiration in Paris, a memoir of life in the French capital by Julian Green, recommended by Andrew Davison, Regius Professor of Divinity at Oxford University. For those planning holidays further afield, then perhaps a biography of Australian opera singer Nellie Melba, recommended by Kate Flaherty, would add a touch of glamour, along with the autobiography of Melba’s friend and fellow performer, Ellen Terry.  

Also falling into the memoir genre is this season’s stand-out recommendation: Helen McDonald’s H for Hawk, which is currently sitting on the bedside tables of Tyler Staton, pastor of Bridgetown Church, Portland, Graham Tomlin and Belle Tindell. Whilst processing the death of her father, McDonald attempts her long-held ambition to train a hawk, and crafts a surprising and poignant book from the twin experiences. 

McDonald is not the only writer to twist multiple strands and genres into her work; many of our guests’ choices defy definite categorisation. Flaherty, a Senior Lecturer in English and Drama at the Australian National University, also recommends Ali Smith’s Artful, which contemplates art, faith, and fiction, and Murriyang: Song of Time, a ‘psalter’ according to its author, Stan Grant, combining Christian and Australian aboriginal spirituality.   

Changing spiritualities are also on the mind of Chine McDonald, the Director of Theos think tank and the first guest to return to Re-enchanting following her initial appearance more than a year ago. On McDonald’s reading list is The Afternoon of Christianity: The Courage to Change by Tomas Halik, who ponders Christianity’s midlife era and what lies ahead for the faith and faithful alike. One way in which the world has changed over the last century is through the withdrawal of ritual from Western society, according to the German-Korean philosopher Byung-Chul Han, whose book The Fading of Ritual—or Vom Verschwinden der Rituale for any German speakers among us—comes with a recommendation from Esther Maria Magnis. Is the pairing of Halik and Han the literary match that reflections on modern Christianity have been waiting for? 

If imagining the future of the Christian faith sounds too heavy for the summer holiday, then why not dip into some of our guests’ fiction suggestions? From Jo Swinney, Director of Communications at A Rocha, comes the modern classic, A House for Mr Biswas, by Nobel laureate, V. S. Naipaul, whilst Rupert Shortt, who, as a former editor of the TLS, knows a thing or two about books, currently reading S. J. Naudé’s Fathers and Fugitives, which takes us on a journey from London to South Africa into a complex story of family, sexuality and relationships.  Readers looking for short form fiction could opt for either Ben Judah’s This is London: Life and Death in the World City, or for a more international perspective, Dream Count, the latest novel by renowned Nigerian writer, Chimamanda Ngozi Adichie. 

And, finally, Les Isaac, the founder of Street Pastors, reminds us of the importance of responding to the Bible itself. So, if you’re looking for gut-wrenching narratives and a sense of wonder playing out through characters who are just all-too-human, then look no further than the book which in the Middle Ages was known as a bibliotheca, a whole library in itself.
