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.

This is why we must go down to the sea

Stepping off the shore restores more than our sanity

Paul is a pioneer minister, writer and researcher based in Poole, Dorset.

It’s that time of year again. Much of Britain has been enjoying (or possibly enduring) a heatwave, the summer holidays are approaching, and our thoughts naturally turn toward an escape from our ordinary, often urban, landlocked, lives. And for many of us that escape will be to the sea. It’s true, we really do like to be beside the seaside. As a nation our souls seem to suffer from an annual experience like that described in John Masefield’s poem Sea-Fever as we head coastwards muttering ‘I must go down to the sea again...’  

We want to holiday by the sea – as the market for second homes in places like Cornwall will confirm. We also want to live permanently by the sea, or at the very least by the water. Some experts estimate that properties by the water have an average increased value of around 48 per cent. Water sells. It does so perhaps because proximity to it provides something of a mental escape from the overwhelming rigidity and linearity of our predominantly urban environments.  

Iain MacGilchrist has argued that our modern lives suffer from the triumph of the left-brain hemisphere’s attention to the world. This is a focussed attention that is all about controlling and getting. It leads to the creation of a self-contained and ordered world with little attention to context. And so little attention to the natural, complex, fluid reality of creation. MacGilchrist goes on to correlate the rise in a variety of mental illnesses characterised by what he calls ‘right hemisphere deficits’ with industrialisation and the development of our culture of modernity.  

In his book Blue Mind Wallace Nichols explores the evidence for the positive effect of water on the brain. He highlights how a proximity to water can heal, restore, give us a sense of connection and promote calm. He argues that water can shift our minds into what he calls ‘drift’, the kind of mental attention which generates calm. Being with, on, better still in water, is undoubtedly good for us. No wonder we are drawn to it.  

Yet at the same time water, and particularly the sea, has been a source of terror. A no-go area ‘where there be dragons’, OK, lobsters for sure, probably sharks, and whales like Moby Dick. The sea remains one of the last places of mystery, an unfathomed, unfathomable place of endless dark water. We know more about the far reaches of the universe than we do about the truly deep ocean. Mythical creatures of the deep, whether Nessie, or one of various giant specimens hauled unsuspectingly from the ocean, continue to populate the diminishing space of our wonder and fear of the unknown.  

So whilst elucidating the psychological benefits of water is certainly helpful, it’s all a bit…tame. Is it just another way of humans turning the wild and numinous into something we now think we understand? Something we can now control and apply in our lives for our own benefit and comfort? Have we demystified the sea? Reducing its mysteries to little more than a balm for our troubled modern minds? A lure for our attention and our debt in an overheated housing market? 

In the Christian tradition the sea is a place of profound paradox. Creation begins with God’s Spirit hovering over the water. However, the Hebrew scriptures also present the sea as a place of God’s absence. The sea is the place of monsters and mystery, and death. It’s also the place of perhaps the most famous whale in all literature. The whale that swallows the hapless Jonah. Jonah’s story expresses the deep paradox of the sea as a place of death and yet also a place of divine encounter. It is in the depths of the sea, and the digestive system of the whale, that Jonah’s epiphany takes place and his journey starts anew. 

Stories of Jesus also deal with this paradox of wildness and encounter in the chaos of the sea. In the story of the calming of the storm the wild threat of the sea is not rendered as simply something to be avoided. Jesus is not a fixer making all daily dangers obsolete. Rather the story says that it is precisely in such moments of wildness, fury and terror that his powerful presence can be encountered.  

To step off the shore and into the sea is to enter the possibility of the death and (paradoxically) the real possibility of deeper life.

It’s for these reasons perhaps that, John Good, a friend of mine, has formed a Christian community that’s based around encounter with the sea. Located as it is in an area almost surrounded by the sea, it started as a social enterprise helping people access the water who otherwise lacked the equipment or resource to do so. Pretty soon it became clear that this was transformational for people. Enabling families otherwise excluded from a life-giving resource to enjoy it as much as anyone else was powerful. One person referred to the experience by saying that on that day the sea had been ‘her saviour.’ Ocean Church began with a gathering on three large, tethered paddleboards some metres offshore. They now run retreats and pilgrimages on the sea, practice centering prayer (a form of Christian meditation or contemplative prayer) on the sea and continue to explore what it means to meet God on the water.  

We yearn for the sea, and the water, for more than a balm for the mind. The sea remains that place, in our mechanised, technological world with its constant lure of control and mastery, where an immersion in dangerous mystery can still be experienced. To step off the shore and into the sea is to enter the possibility of the death and (paradoxically) the real possibility of deeper life. To be held buoyant by the sea and look to the horizon is to get it touch with our finitude in the context of the vastness of the seas. It is to engage with our utter dependency on the creation which we inhabit and to connect with the presence that holds that creation together.  

To step into the sea is even therefore a step of faith. A step in the direction of our own vulnerability. A brave step away from the world in which our technology, our algorithms, our machines and our skyscrapers dupe us into a faith in our own control, our own supremacy. A step into the depths. ‘Deep calls to deep’ says the psalmist as ‘all your waves and breakers have swept over me.’ As many of us step into the sea this summer it may certainly be a step toward a restored sanity, but it might also be a step toward a restored soul.
