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.

Death focuses our minds on what really matters

From ballet tales to royal soap opera, stories shed light on Lent's dark mortality.

The season of Lent – the 40 days of penitential fasting preceding the great feast of Easter – is unavoidably about death and dying. Christians try to die to sin; the season culminates with the brutal, if salvific, death of the Christ on the cross on Good Friday and it’s said that if we, as disciples, can’t die with him at Calvary, then we can’t truly know what it is to rise with him at Easter dawn.

Those of us who attend an “ashing” service at church this Ash Wednesday, will have a cross traced on our foreheads by a priest, made from the ashes of the palm crosses from last year’s Palm Sunday, with the words: “Remember that dust thou art and unto dust thou shalt return.”

Reprising folk goddess Joni Mitchell, we’re thus reminded that we are but stardust and these bodies that we lug about are all bound towards that destination. In short, we’re all going to die.

So as signs of new spring life are appearing all around, the Christian Church starts to wallow in existential misery. To paraphrase the lugubrious Mona Lott (geddit?) from the wartime BBC comedy It’s that Man Again, it’s being so cheerful that keeps we Christians going.

Against this, I’d like to mount a case that there really are reasons to be cheerful in Lent; that, if the words of the ancient Gregorian chant that “in the midst of life we are in death” are true, then the reverse is also true, that in the midst of death we’re living life.

Dead, but alive again. Lost, but found. These are the qualities that ameliorate the dark mortality of Lent.

This thought comes to me partly because of the extraordinary reconciliation and peace that families often experience as they lose one of their loved number. And it comes partly having just watched a livestream of the Royal Ballet’s latest production of Manon. Our heroine dies in a New Orleans penal colony, having been exiled as a prostitute from bourgeois Paris, sustained at the end not by worldly wealth but only by the devotion of her lover.

It’s quite a story – catch it if you can. It contains the key tenet of faith during Lent, that love conquers death. Having embraced our Lenten mortality, that’s the truth we endeavour to embrace at Easter. And that, for me, begins to put the love back into Lent, which is otherwise bleak and bitter, like the sour wine offered to the dying Christ.

My case is that it takes our mortality to clock what’s really important. And we witness that human realisation all the time. I believe we’ve just seen it in Prince Harry’s transatlantic flight to visit the King on his cancer diagnosis. King Charles becomes simply a dad again when his son is presented with the reality and realisation of his mortality, that sooner or later he is going to die.

As it turns out, that reality turns out to be infinitely more important than whether he got a smaller bedroom than his big brother when they were boys (copyright Spare, Bantam Press).

It’s stories like these – from Manon to the soap opera of the modern royals – that put human mortality into bas relief, so that we can see it properly. But it’s particularly Harry’s mercy mission to his father that chimes, for me, with a gospel story, or parable as we call them.

It’s not one that’s about kings or weddings – or even principally about death and dying. I’m thinking of the Parable of the Prodigal Son. Plot synopsis: A landowner has two sons. The younger one asks to cash in his inheritance and travels away to a foreign land, where he spends all he has on a debauched lifestyle (cf. the Paris from which Manon “escapes”) and is reduced to tending pigs and coveting their swill. He returns humbled to the family estate, where his father welcomes him with a feast, much to the consternation of his brother.

Sound familiar? Sure, Charles isn’t God, as we assume the forgiving father to be in the parable. Nor is Harry asking to return, humbled and repentant (though we don’t know that, do we?). Nor has he been reduced to a diet of pigswill, unless California and Netflix contracts count as that.

Possibly more accurately cast is Prince William as the elder brother, who in the parable objects to his sibling’s welcome back, pointing out that he’s done all his father’s work without such reward.

Here, for our Lenten purposes, the father’s reply is key: “My son, you are always with me, and everything I have is yours. But we had to celebrate and be glad, because this brother of yours was dead and is alive again; he was lost and is found.”

Dead, but alive again. Lost, but found. These are the qualities that ameliorate the dark mortality of Lent. For royals, commoners, the trafficked, the desperate and alone, it delivers the one thing that death can’t extinguish: Hope.
