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.

Why do films portray Christians as crazy?

Exploring why films often portray the god-fearing as ‘always so god-damn weird’, psychologist Roger Bretherton recalls a first divine experience.

We knew we were in trouble when he started quoting the Bible. If there is one rule we should all follow in a zombie apocalypse it is not to trust the isolated community of believers huddled around a Bible-quoting preacher. You know the plotline. The one that never occurs in Star Trek: the crew of the USS Enterprise land on a paradise-like planet only to discover that everything is exactly as it seems. No. The rules of genre television must be upheld. If it seems too good to be true, it probably is. 

This was the strong suspicion my eldest child and I immediately leapt to while watching season one, episode eight of HBO’s The Last of Us. If you haven’t seen it, it’s a zombie apocalypse drama, a bit like The Walking Dead, but with more giraffes and fewer zombies. Is it a virus? Is it radiation? No, it is a fungus that has zombified the masses. Starting with a few isolated infections here and there it rapidly mushroomed (I guess) to turn the placid citizens of the world into manic flesh-eaters. All I’m saying is keep applying the anti-fungal toenail cream, it may be the only thing standing between us and the collapse of civilisation as we know it.  

So, when episode eight opened with a previously unknown character quoting the Bible to a fearful flock hiding in a diner, we knew things weren’t going to turn out well. The signs were all there. He was almost definitely a paedophile, possibly a murderer, and very likely a cannibal. As it turned out we’d hit a perfect straight: three for three. He was all of them. I probably should have issued a spoiler warning for that one, but to be honest if you didn’t see it coming The Last of Us probably isn’t for you. You’d probably be happier watching something more sedate. Silent Witness anyone?  

Needless to say, the episode provoked no small amount of theological commentary in our household, mainly querying why it is that anyone exhibiting even a modicum of Christian belief in shows like this, almost always turns out to be completely unhinged. Why do the righteous always have something wrong with them? Why are the god-fearing always so god-damn weird?  

Pray and take the pills 

Just to be clear, I’m not a murderer, nor a paedophile, nor a cannibal (and I have no plans), but somehow the prejudice that Christians must be crazy has come to influence how I view my own spiritual history. I have inadvertently imbibed the simple naturalistic logic that if I am a Christian then there is something wrong with me. Some part of me shakes hands with Freud and retrospectively attributes my conversion to neurosis, a coping strategy, a crutch. The assumption that the only reason I would believe something so unusual, so out of step with the people I spend most of my time with, is that I am weird. Quietly, without realising it that is how I have come to view it - I need God because I am weak. 

Of course, religion can and often is used as a coping strategy. Leading psychologists of religion, like Kenneth Pargament, have made entire careers out of studying this phenomenon. For several decades, he and his collaborators have demonstrated pretty conclusively that people use religion and spirituality as potent sources of coping with the pain of life. From this perspective, religious conversion can be viewed as a transformation of significance. When the things we previously relied on to give us a sense of meaning and stability fail us, when our adjustment to life falls apart and cannot be put back together, we give up trying to conserve what was previously meaningful and instead take a transformative leap toward a new view of what matters to us. When the going gets tough, the tough get going. When the going gets too tough, some people turn to Jesus.  

But there are many ways we can use religion to cope, and over the years Pargament and his collaborators have identified a few of them. Some people defer everything to God, they cope by thinking God will do everything for them, they plead for Him to intervene. Others are self-reliant, they may believe in God, but they don’t expect much from Him; for them prayer is more like therapeutic meditation than anything medically effective. Others cope in a collaborative way. They don’t leave it all to God, nor do they think everything centres on them. They take responsibility for their lives, but view God as a companion, a collaborator, a conversation partner through all the vicissitudes of life.  

It probably comes as no surprise that in studies of religious people dealing with chronic illness, these styles of coping significantly predict prognosis over time. There are many ways it can help us, and some of them are more admirable and effective than others. Those who leave it all to God usually do worse, those who think it’s all down to them do better, and those who pray and take the pills do best. Coping with a painful and bewildering world is undoubtedly one of the benefits of religious belief. It’s one of the things it does for us, but it is not what religion is at core. It may be a function of belief but not its essence.  

That first intimation of divine presence... It was the teaser trailer of a movie I was yet to see. A tiny taster from an infinite menu. 

As a twelve-year old boy, lurking at the back of an old Methodist church, waiting in silence for the possibility of something sacred to be unconcealed, I was not the kind of child anyone at school would ever admire: lonely, bullied, ignored. Relegated to the corner of the playground reserved for the outcasts and untouchables, the overly sensitive gay kid, the boorish tractor enthusiast, and the Dungeons and Dragons players. When I revisit the moment of my first truly transcendent and mystical experience of God, it’s tempting to write it off as an imaginative invention designed to anaesthetise the pain of social exclusion. I needed it to be true, so I made it up.  

Yet there is more to it than that. That first intimation of divine presence was the beginning of a lifelong quest to experience more. It was the teaser trailer of a movie I was yet to see. A tiny taster from an infinite menu. And in the years that followed I pursued it. To begin with, that strange sense of presence was elusive. I couldn’t generate it under my own steam but ran across it every few months, in a small group, a church service, a prayer meeting, a piece of music. Over time the frequency increased, as I learned patterns of prayer and spiritual practice. Eventually, decades later, it stabilised into an almost daily occurrence. I discovered the western mystical tradition, a historical lineage that made sense of what I was sensing, and to which I could belong. I made myself at home with Augustine of Hippo, Julian of Norwich, Ignatius of Loyola, Teresa of Avila, John of the Cross, Thomas Merton. My new extended family was large and varied. They became my friends and spiritual guides. I had a history. 

When I think of the creatives I know, the artists, writers, actors, and musicians I have spent time with, I notice that for many of them their art is a response to the tragedy of life. But I rarely judge their work on the loneliness and pain that drives their compulsion to create. All too often it is the aching that lingers just under the surface of their work that makes it poignant and affecting. It is not just the beauty of what they create that moves me to tears, it’s the heartbreak out of which it is composed.  

My spiritual journey seems somewhat similar, a creative enterprise launched and sustained by a new insight into the nature of the world. Faith is more like a new way of seeing, than a new set of propositions to believe. If I’d been happy and fitted seamlessly into the fabric of social life, I doubt I’d have been open to the experience or able to recognise it when it occurred. But just as we might hesitate to reduce an artist’s work to little more than psychological self-help, I find myself increasingly reluctant to view my spiritual history as just an expression of my own neurosis. There is another way to tell the story, one that emphasises not so much the problems that drove me to God, but the presence that drew me to Him. There is more to the story than my own neediness and, in the final analysis, when the zombie apocalypse comes, at least I have retained sufficient sanity to avoid the guy with the Bible.
