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.

Kate Winslett delivers the performance of her life, in a film that doesn’t look away

The true quality of witness shines in Lee Miller’s biopic.

If we might indulge an absurd anachronism, I wonder what the American photojournalist Lee Miller would have done, had she been one of the women at the foot of the cross. To my mind, she would have held her nerve to record – on her German-made Rolleiflex camera held at her abdomen – not only the horror of the crucifixion of Jesus of Nazareth and the criminals beside him, but also the suffering of his mother and the other women who looked on.

I’ve had these ruminations since I watched Miller’s biopic, Lee, on its UK premiere. In passing, I should record that Kate Winslet delivers the performance of her life in the title role, because it’s in the quality of her interpretation that I’m led to consider the nature of what it means to witness, which is an act at the heart of humanity as well as central to the Christian faith.

Witnessing is what reporters, at their best, do if they are to honour their vocation. Especially war reporters. But the act of witnessing isn’t confined to journalists. The case for professional witness can be made for other jobs – police officers, aid workers, medics, lawyers all come to mind.

It’s just that this movie shows witness at its sharpest end. “Even when I wanted to look away, I knew I couldn’t,” says Lee Miller. That imperative, not to look away, is central to our human story and I would argue that this is because it’s central to my faith, which has at its centre a God who doesn’t look away.

That’s why Lee Miller made me think of the historical event of the crucifixion. The Church down the ages has been inclined to turn the cross into the Christ’s great victory – rather as reportage of the Second World War has concentrated on its conclusive victory rather than the horrors that Miller recorded.

Her magazine employer, Vogue, at first declined to publish her photos of the liberation of concentration camps Dachau and Buchenwald, in part because it detracted from the joy of that victory (though they were subsequently published in the US). If you will, Vogue looked away.

I’ve found that to go down this path with Miller, accompanied by faith, a kind of terrible road to Emmaus, delivers some unexpected reactions.

We’re called to refuse to look away from the grotesque horrors of the cross, to resist it becoming simply a jewellery symbol on a pendant, to acknowledge its centrality in man’s inhumanity to man and, ultimately, our God’s choice to share that experience. “Jesus Christ,” mutters Miller at the door of a room, possibly a gas chamber, stacked with skeletal corpses, before entering to take her photographs. Jesus Christ, indeed.

This is not to make a claim for Miller as a figure of faith. It is rather to make the claim that those of us of faith should be highly alert to where we might find the witness to it. Over the past week, I have to say I’ve found it in the work of Miller, not only in the hell of the camps, but in the shaven heads of collaborator women, the frightened children and even in that bath in Hitler’s Munich apartment.

In the last of those, there she is, naked, washing herself clean from the dirt of Dachau, which stains the bathmat from her boots in the foreground. Here is a witness to a spiritual defiance, the portrait of Hitler propped on the bath edge as she is cleansed. It’s not just that he hasn’t won, it’s that death itself hasn’t won.

I’ve found that to go down this path with Miller, accompanied by faith, a kind of terrible road to Emmaus, delivers some unexpected reactions. And they’re not the kind of reactions normally associated with faith.

The first is anger. It clearly accompanied Miller throughout her work: Anger at military discrimination against her womanhood; rage that Vogue censored her work. We could all do with being more angry at injustice, especially those of us of religious faith. Note that when American Vogue published her photos, they headlined them “Believe It!” True belief, arguably, is angry.

My second takeaway is the danger of real witness. Miller described her work as "a matter of getting out on a damn limb and sawing it off behind you". Discipleship can, maybe should, be like that.

The third is the cost of witness. Miller’s war left her with depression and what today would be called PTSD. Not looking away has its price. The cost of witness to disciples may not be as extreme as it was in the first century of its practice, but we should also be aware that it’s not a cosy lifestyle choice either.

For Miller, part of the price of her witness was alienation from her son, Antony. In the movie, though (spoiler alert), he discovers after her death how devoted to him she was. At a stretch I would say he was a son in whom she was well pleased.

That’s not to imbue her with something messianic. It is perhaps to say, with the poet Philip Larkin, that what will survive of us, especially those who have witnessed the worst of humanity and come through, is love.
