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.

'The smell of dust and damp stone will always cry “safety!”'

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.

Letter from the Balkans

An audience with a crown prince tells the story of troubled lands and resilient inhabitants.

It’s only halfway through our supper by Stone Gate, the most ancient entrance to the old citadel of Zagreb, Croatia’s capital, that we realise votive candles are burning in the archway outside. Closer inspection reveals three or four simple pews before a niche shrine to Our Lady and the stone walls covered with inscriptions to the local deceased.

Families, young and old but mostly young, gather in the gloaming for their dear departed. This is a profoundly Catholic site and the little restaurant, brightly lit and jolly, nevertheless feels reverential and on holy ground. Some 80 per cent of the population of Croatia is Roman Catholic, while just 3.3 per cent are Serbian Orthodox.

A five-and-a-half-hour bus ride east and we’re in Belgrade, capital of Serbia. Here, the proportions of the faithful are almost exactly reversed – 81 per cent are Orthodox and a little under four per cent Catholic.

These statistics serve as a grim reminder of the phrase that entered our political lexicon in the first half of the 1990s: Ethnic cleansing. In that civil war, as the former Yugoslavia broke up into its constituent republics, Croatian Serbs and Serbian Catholics – those who survived, that is – were displaced.

So we’re less likely to see the kind of Marian devotion that we witnessed in Zagreb being honoured in Belgrade. This is essentially a technical, creedal difference between Catholicism and Eastern Orthodoxy, in how the incarnation of the Son proceeds from the Holy Spirit. It’s no big deal theologically and shouldn’t detain us. But it quietly points to the fragility of peace, not to say democracy, in the Balkans.

A mural depicts an icon of Christ with a bullet hole in his forehead.

HRH Crown Prince Alexander, head of the Royal family Karadjorjdevic, which ruled the kingdoms of Serbia and (later) Yugoslavia until the Second World War, carefully refers to it as “democracy at midnight” over coffee in the Blue Room of Belgrade’s Royal Palace. He returned to his ancestral home when Slobodan Milosevic was deposed at the millennium.

The Crown Prince helped his country return to democracy by uniting the opposition which defeated Milosevic in the elections of 2000. Even today, he calmly states that western democratic leaders often fail to understand how the mindset of eastern autocracy works and agrees that it is “work in progress”. Eternal vigilance is key.

In this context, the Serbian Orthodox Church is doing well, but it’s also still work in progress. Under communism, a substantial number of Serbian bishops were appointed by the Soviet regime, for purposes of control and information gathering. That culture wasn’t cleansed overnight, nor has the communist legacy been entirely expunged from the Church.

“You’ll see what I mean when you visit our family chapel in a moment,” the Crown Prince tells me. Sure enough, a fresco of the Christ in its dome has a bullet hole through the forehead, not so much crucified as assassinated. Prince Alexander will not restore it, so its serves as a constant reminder of what can be. His guiding principle is that “only dictators alter history.”

Elsewhere, our guide points to desecrated icons and the ghostly shadows of Soviet insignia on marble pillars. Alexander is an unassuming and modest man, referring to the 18 Serbian parties he convened at a conference in 2000 as “the democracy by email”.

When we’re joined by his wife, Crown Princess Katherine, she corrects this, proudly stating that her husband returned democracy to the region. There is probably some truth in both their versions of events. The consequence of that could be a restoration of a constitutional parliamentary monarchy in Serbia – we’ll see, or perhaps our successors will.

From the Palace, we visit St Sava, called a temple but really the Serbian Orthodox cathedral consecrated to the memory of the founder of the national Church. This, again, is work in progress. Started in 1935 and only now approaching completion, it’s a paradigm of the troubled contemporary history of Serbia. Communists have razed it and Nazis have parked their trucks and tanks in it.

It is unashamedly modern, though it honours ancient Byzantine mural and fresco methodologies. Its biblical stories in gold leaf use the traditional crafts, linking Belgrade to its ancient past, whatever despots may have done to interrupt its devotional history. We’re linked to the palace we’ve just left by enormous doors, inscribed with multi-lingual prayers of welcome, donated by the royal family.

Perhaps the allegory it offers is best illustrated by the image of Christ – no bullet hole now – in the dome, which was built and raised, centimetre by centimetre, from the ground. All 4,000 tonnes of it. The metaphor of rising from the ashes of war writes itself.

And that’s the takeaway from Belgrade. Serbia – and the wider Balkans – suffered a 20th-century of unfathomable bleakness. Its people have endured and their spirit isn’t broken, a moral exemplar for western Europe. Belgrade resonates to its folk music and young laughter over broken bread and wine outpoured (gosh, do they eat and drink – for who knows what tomorrow holds?).

The phoenix, which naturally shares Greek roots with Serbian royalty, would be the go-to cliché for the cyclical regeneration of Belgrade. But as this city approaches Easter, there is of course something else more fundamental going on.

Belgrade has faith in itself, as well as the God who has delivered it. It’s a resurrection story really.
