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.

Symbols in culture – the interface between the Seen and the Unseen

Open your eyes.

As December gives way to January, we become conscious of time rolling on from one year into the next.  

The moment is often marked by that most famous image of the New Year: the Roman god Janus standing sentinel at the threshold; two-faced, gazing back into the past, but also forwards into the future.  

The double-faced god is a striking symbol to depict this interface of time. But we also often find symbols at another important interface: the place where the Seen meets the Unseen. 

Symbols have always existed at this touch-point - between the spiritual and the material. We might even say between heaven and earth. Symbols possess a power which goes beyond the strictly rational. They are more than their constituent parts. 

In the moment when Jesus effectively instituted the church, he tells his disciple Peter: “Behold, I give you the keys to the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” Here, Jesus not only uses symbolic language with his image of the key, he also assigns Peter (and so the church) a divinely-appointed role: to stand there at this threshold between the seen and the unseen, and to have an effect. 

The mission then, to occupy and influence this frontier between both realms, is significant. It’s worth considering – especially at this liminal time of year - what a culture’s symbols say about its direction of travel. What are the symbols that saturate our conscious and unconscious world? What effect are they intended to have by their creators? What influence do they actually have in the seen and unseen? 

Our culture is saturated with symbols that were always meant to exert influence in the unseen. Some consciously; other maybe less so. 

The notion that symbols act on reality is not a merely Christian concept. Far from it. In many cultures, the origins of written communication have often been interwoven with both mystery and magic. The futhark, for example – the basis of the Old Norse runic alphabet in Scandinavia – developed directly out of shamanistic practices. In a word: witchcraft. Certain symbols were graven into material objects in order to have a specific effect. A rune for protection carved into the haft of a warrior’s axe; a rune for fertility on a woman’s comb or belt. Symbols to curse; symbols to bless. All intended to manipulate the reality around them. Effectively they acted as a kind of spell. 

Roll the wheel of history forward a bit and we see the cross itself became a powerful symbol across the developing civilizations of the world, especially in Europe. Making the sign of the cross became synonymous with an invocation of God’s blessing or else protection against some evil. An outcome all the more extraordinary when one considers the origin of its use – a shameful incident of execution, standing on a lonely hill. 

Similarly, the Crescent represents one of the great symbols of history, often in antagonism with the Cross. Think of the symbolic reversals still visible in the architecture of some parts of Spain. When the Iberian peninsula fell to Moorish conquest in the early eight century, the cross was torn down, all symbols of Christian faith effaced, only to return eight centuries later with the Reconquista. Today, you can see still the Cross surmounted on clearly Moorish architecture, a visible sign of those historic conflicts. 

Such warring symbols of unseen spiritual realities are hardly consigned to the history books. Witness perhaps the most live example playing out all across the cities of Europe. The Star of David opposed and disdained by those waving black, green, red and white flags. 

Nor is the clash of symbols simply a matter between the great religions of the world. The rainbow flag represents a certain positioning within the realm of the unseen wherever it is planted. In other contexts, our culture is saturated with symbols that were always meant to exert influence in the unseen. Some consciously; other maybe less so.  

Apple’s ‘apple’ is not just an apple. It is an apple with a bite taken out of it. Elsewhere, symbolic representations of devil horns proliferate – to be expected on heavy metal t-shirts and album covers; perhaps less so throughout myriad children’s TV shows and movies across our streaming channels. Yet they are there.  

The ‘One-Eye’ symbol has been associated variously with freemasonry, Luciferanism, Satanism and the occult. It appears in anything from pop videos to movie posters to political protest logos (“Just Stop Oil” anyone?). Even a ubiquitous pose-for-camera for celebrity photo-shoots. Once you clock it, you’d amazed how prevalent this symbol is across our culture.  

Does it signify anything? Or nothing at all? 

You have to assume that the creators of such symbols don’t include them by accident. Some are hidden in plain sight; others are brazen and bold. Either way, they are meant to be there. But why? 

Symbols have always been used in the casting of spells. These days, we give so much head space to the consumption of culture, myriad symbols flashing in and out of our consciousness as we scroll ever onward, have we any idea what spells we are subjecting ourselves to – irrespective of whether we believe they are effective or not? 

Against such murkiness, perhaps this season of Christmas rolling into the New Year is a good time to consider what some might consider the ultimate symbol appearing in our reality of the Seen: the Incarnation.  

In a way, Christ identified himself as the visible interface between the seen and the unseen when he said: Whoever has seen me has seen the Father.  

And yet, the Incarnation also transcends the mere symbolic. Yes, Christ points to an unseen reality, but he is also the ‘thing’ itself. He is both Seen and Unseen in one. Not a symbol pointing to something else, but the thing to which all symbols ultimately point: the central reality in the universe where God and creation meet.
