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.

My conversation with... Tom Holland

Noticing that Tom Holland is the star of The Rest Is Politics Christmas special, Belle Tindall is remembering her conversation with the historian earlier this year.

Belle is the staff writer at Seen & Unseen and co-host of its Re-enchanting podcast.

Tom Holland recording the podcast at Lambeth Palace Library.

In a festive one-off, two worlds have collided. Tom Holland, of the beloved 'The Rest is History' podcast, has joined Rory Stewart and Alistair Campbell in their 'The Rest is Politics' parallel universe. They spend a merry hour talking through religion, politics and the way in which they have both shaped our modern world... plus dinosaurs, always dinosaurs. 

And it got me reminiscing - my mind drifted back to earlier in this slightly odd year, on the eve of the coronation, when we had the one and only Tom Holland on our podcast. We called that episode of the podcast - Re-Enchanting History and the Coronation - but for me, it could just as aptly be entitled Re-Enchanting the Weird.  

Below is a reflection that I wrote immediately after that fascinating episode was recorded. If you've enjoyed his appearance on The Rest is Politics, you may just enjoy his appearance here too.

Re-Enchanting the Weird

Let me start in the proper place, with introductions.  

If you are a fan of history, Tom needs no introduction. But, for those of you who are not yet acquainted with his wonderfully infectious expertise, Tom is the co-host of the beloved podcast, The Rest is History (alongside Dominic Sandbrook). He is also the best-selling author of Rubicon, Persian Fire, Dominion, and the up-coming book for children, The Wolf-Girl, The Greeks, and The Gods. Justin Brierley and I recently had the pleasure of soaking up a little of Tom’s extensive knowledge when we interviewed him for a Coronation special of Seen and Unseen’s Re-Enchanting podcast.  

Tom’s most recent book, Dominion, charts the mighty impact that the Christian revolution has had; beginning with its unexpected origins and following its cultural reverberations through to the present age, highlighting its very present influence. We are, to borrow Tom’s own phrase, a society of goldfish who are (perhaps unknowingly) swimming in a distinctly Christian fishbowl. And so, our conversation began there – as he pointed out that, like it or not, the West operates in the residue of the Christian revolution. Christianity has been hidden in plain sight all along. For the sake of eloquence, I’ll let Tom explain:  

‘The conceit of the West is that it’s transcended Christianity to become purely universal, purely global. But its values, its assumptions, its ethics remain palpably bred of the marrow of Christianity’.  

Throughout our conversation, Tom took us on a whistle-stop tour of what was, what is, and the thread that can be drawn between the two. And while I don’t wish to spoil things for you, I imagine you can guess what the thread is. This conversation touches upon the origins of democracy (as we perceive it), the Reformation and the Nazis, to name but a few. I couldn’t recommend it enough. But I must warn you, you cannot un-hear Tom’s observations. The things he points out, you simply cannot un-see. Christianity will no longer be hidden; it will just be in plain sight.  

Seen as it is within in touching distance, we also wanted to get Tom’s thoughts on the Coronation. And this is where the re-enchantment of the weird began. At least, for me.  

The very notion of this upcoming Coronation is odd. It is a distinctly peculiar event.  

Firstly, it is incredibly old. We are the only country in the world that still does this particular thing in this particular way. What we will see unfold before us is derived from the 10th Century, when King Edgar was coronated by St. Dunstan, and yet it goes back further still - its roots actually lie in Bronze Age Israel.  

During the Coronation, the ancient and the modern will converge. As spectators, we will be peeking into times gone by; as Tom (rather excitedly) said, watching this ceremony, and everything that will surround it, will be like ‘seeing a dinosaur… still alive… in a zoo’. I wrote that last week’s conversation with astrophysicist, Dr. Jennifer Wiseman, made me feel small – small in time and small in place. Well, in many ways, so did Tom’s thoughts on the Coronation. The ritual is so very old, and we, so very young.  

But there is more. Tom reminded us that the Coronation is not only old, it’s weird. It places the mystical, the supernatural, the sacred, and the down-right strange on centre stage.  

Nick Cave, who will be sitting in Westminster Abbey on the day despite not being much of a royalist, explained that he accepted the invitation purely because of its bewildering oddness. In his Red Hand Files, he wrote  

‘what I am also not is so spectacularly incurious about the world and the way it works, so ideologically captured, so damn grouchy, as to refuse an invitation to what will more than likely be the most important historical event in the UK of our age. Not just the most important, but the strangest, the weirdest.’  

Both Nick Cave and Tom Holland have allowed themselves the fun of being curious. Curious about the fact that something profoundly supernatural is about to be taken incredibly seriously in the heart of a so-called secular society. And whatever pragmatic questions I may have about the place of monarchy in the here and now, I think I will allow myself the fun of being curious about that too.  

My conversation with Tom re-enchanted the parts of Christianity that, as someone who grew up as a Christian, I used to be quite embarrassed by. Namely, the weirdest parts.  

As a teenager, my instinct was to minimise (at least in public) the aspects of the Christian faith that cannot be explained by rationalism. I used to keep quiet about the parts of my faith that outed me as someone who believed in things that are supernatural. I would try my absolute best to blur the details of the most obscure facets of Christian thinking. But, as Tom said, ‘a Christianity that has bled itself of enchantment is a pallid thing.’ And if there is one thing that the whole Jesus movement was not, it’s pallid.  

If you, like Tom Holland, crave enchantment, this episode will be for you. Afterall, what better place to go looking for the wonderfully weird than in the ‘greatest story ever told’?
