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.

Hedgerows are boundaries, but they don’t divide so much as abound

The lines we draw between land and lane connect us.

In May and June, the Devon hedgerows that hold the landscape outside my window are at their fullest, most colourful state of being. Walking the narrow lane that runs away from our house means walking between high hedgerows that rise like soft green walls either side, which really, means walking between ancient living things, because these hedgerows are old. Devon has some of the oldest hedgerows in the country, and so the world – older than the Parish churches whose towers I can see to the south, east, and west, which rise like old-growth trees out of a blanket of green fields.  

Early Bronze Age farmers had to clear woodland to make their fields, and sometimes they left strips of woodland to mark boundaries. These are our oldest hedgerows. They are often found on parish boundary lines, and can support over 2,000 species, also acting as important wildlife corridors for many of them. To roughly date a hedgerow, you count the number of species in a 30m stretch – one species equals 100 years. I have taken to counting random 30m stretches of the hedges that line the lanes near us, and have concluded that we are surrounded by hundreds, in places thousands of years of history – of braided hawthorn and blackthorn, hazel and oak, pink campion and bluebell whose bulbs hide in ancient earth banks that many of the hedgerows sit on.  

Now, in these spring hedges, hawthorn is in blossom, nettles overflow with prickly exuberance, and somewhere deep in the tangle a blackbird tunes its song. The hedges are thick with memory stitched together from centuries of hand-laying, stock-keeping, quiet watching. They are Devon’s old boundaries, but they do not divide so much as abound. Life spills from them: wrens and mice, vetch and violet, and so many more things unseen. These are not just boundaries that mark where other things like fields and roads begin and end then; they are living spaces in their own right. They are pathways for diverse life, they are structures that hold home and shelter, food and safety, they are corridors that contain history and story. They are not just edges, they are the centres of whole lives and worlds.  

Walking here one May morning, I find myself wondering about the lines we draw – between land and lane, but also between ‘us’ and ‘them’ – and whether these lines too might be porous like the hedgerows, which have lived for so long not through independence but through care and relationship.  

The hedges speak paradoxes that I am confronted with every time I go for a walk – of division and abundance, of separateness and connection, of containment and invitation. Lately, I am sitting with these and am coming to understand a threshold that the world offers me: between independence and interdependence. But the truth is I’m not very good at interdependence. I have so often retreated behind the wall of my self-sufficiency, but I am trying to pull that wall down and replace it with a porous and lifegiving hedgerow.  

We draw lines – around ourselves, and between people, nations, beliefs, social classes, politics. Sometimes these lines are for safety, sometimes for exclusion. But the hedgerows tell me that it is possible to hold a line and also to let light and life flow through it and shape it. They tell me that these lines are not end points but invitations to communion.  

In The Left Hand of Darkness, Ursula Le Guin wrote:  

“…I know people, I know towns, farms, hills and rivers and rocks, I know how the sun at sunset in autumn falls on the side of a certain plowland in the hills; but what is the sense of giving a boundary to all that, of giving it a name and ceasing to love where the name ceases to apply? What is love of one's country; is it hate of one's uncountry?”  

Le Guin’s work of science fiction is about otherness and connectedness, with different species having to learn empathy in order to collaborate and communicate. The darker the events in the book, the brighter the hope and relationship. The book feels like it was written for now, for this world.  

On my hedge-edged walks I am in the presence of lives so unlike mine – plants, creatures, the people who have tended and cared for these hedges through generations.

In a world whose people are persecuted, othered, tired, it is easy to believe that the way of things is division and separation. But hedgerows suggest another way to live: layered, porous, complex and interconnected, creating space not just for encounter but for new life through that encounter. This is how I picture the Kingdom that Jesus speaks about and so often found solace in: a world of intermingling and ever-growing aliveness. I think Jesus would have walked with the hedgerows had he lived in Devon. I think he would have used them to speak of boundary-crossing between heaven and Earth, clean and unclean, Jew and Gentile. I think he would have pointed to them and said, see the tangled beauty of these? They are what the Kingdom is like: held and open, living and lifegiving. This is what I want our future to be too.  

As I walk these old lanes, I am deepening into my hedgerow apprenticeship. I am learning to sink my roots in, to tend boundaries with care, to make space for life. I am also finding that there is nothing in the hedgerows that speaks of self-sufficiency. These ancient, interwoven green features that have defined this landscape are here because of relationships between species. It is easy to talk about the interconnectedness of everything, it is another thing to try to live it – to live like gifts, reciprocity, community, are things that might take the weight of our time. These old hedgerows give me a foothold though – they enliven the overused but hard-to-live idea of interconnection, they show me what it looks like and that it is an approach to life that is patient, strong, sustaining, real.  

When I reach out my hand I can usually find something edible or beautiful in the hedgerow depending on the time of year: blackberry, hazel, oxeye daisy, pennywort, primrose. Yesterday, it was the cow parsley that really caught my attention: its frothing, foaming flourishing. In a few weeks it will give way to what comes next, just as it has always done, just as this world will always do. On my hedge-edged walks I am in the presence of lives so unlike mine – plants, creatures, the people who have tended and cared for these hedges through generations. I am also in the presence of relationship, and of hope.  

Now, with so many crises bearing down on the world, and with anxiety and despair blooming, it is the hedges that remind me of other, older, wiser ways to be. It is the hedges that show me how to root deep into solid ground, and how to reach out to others, and to light, which are so often the same thing.
