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.

Eternal Sunshine of the Spotless Mind: 20 years on

Memory and the meaning of suffering.

Michel Gondry’s Eternal Sunshine of the Spotless Mind came out in 2004. Twenty years on, its stubborn insistence that the memory of pain gives meaning to our lives is as relevant as ever.

I first watched Gondry’s cult classic earlier this year, in the midst of recovering from postnatal PTSD. When we are faced with heartbreak, it can be easy to wish that we could retreat from painful memories, hiding them away until the initial pang has seemingly died down. That was my experience, at least. But I quickly learnt that the traumatic memory of my daughter’s birth would continue to resurface until I processed it and accepted it as part of my life. Just so, Eternal Sunshine of the Spotless Mind teaches us that being vulnerable to suffering is a gift, that suffering itself is necessary to our moral growth, and that our ability to remember the past is an invaluable faculty of the human mind.

The film begins simply, with a meeting between its protagonists, Joel Barish and Clementine Kruczynski. As Joel and Clementine start making small talk, they seem immediately comfortable, almost familiar with each other, and yet the atmosphere is eerie. Soon enough, we discover that Clementine was a patient at Lacuna, a clinic which erased every memory of Joel from her mind after their two-year relationship ended in a painful breakup. When Joel finds out, he asks Dr. Howard Mierzwiak, the director of Lacuna, to do the same for him. As viewers, we now start to wonder: was that meeting we witnessed their very first, or have they met again after their memories were erased, unaware that they loved each other in a ‘past’ life?

This tone of disorientation continues throughout the film, and that’s what makes it so special. As Joel’s memories of Clementine are erased one by one, he realises that the removal of one’s painful experiences is in itself a kind of trauma; what promises to be a relief, turns out to be nothing more than loss.

We experience this sense of disorientation and loss alongside Joel as we jump through snippets of his and Clementine’s happiest and saddest moments together, trying to piece together in our minds a linear narrative of their relationship. While this is happening, the film’s subplot focuses on Stan, Patrick, and Mary, three young people working for Lacuna. As Stan and Patrick, the ‘technicians’, work on Joel’s memory removal, Mary, Lacuna’s naive receptionist, muses on the beauty of their mission. She begins quoting aloud the passage of poetry which inspires the film’s very title, taken from Alexander Pope’s verse epistle Eloisa to Abelard (1717):

How happy is the blameless vestal’s lot!

The world forgetting, by the world forgot.

Eternal sunshine of the spotless mind!

Each pray’r accepted, and each wish resign’d.

Mary has an idealistic vision of her work: she believes she is helping suffering people experience the kind of ‘eternal sunshine’ that only a ‘spotless mind’ can achieve. But the human mind is not so simple. Joel’s desire for forgetfulness quickly turns nightmarish. As he realises he has made a mistake, he starts fighting to retain the memory of his love for Clementine, but his is a hopeless quest. Dr. Mierzwiak’s intervention ensures that the procedure is completed.

Left alone without Stan and Patrick, Mary confesses to the married Dr. Mierzwiak that she is in love with him. It is at this point that her idealism crumbles down. He reveals that they’ve already had an affair in the past and that she agreed to let him erase its memory from her mind. Mary is devastated. She decides that what Lacuna is doing is unethical - even if Mierzwiak technically has the patients’ consent to the procedure - and releases the clinic’s files back to the patients. It is this decision which leads Clementine and Joel, just a few days after they ‘meet’ again, to discover that they’ve already loved each other in the past.

Accepting suffering and holding it in our hearts, not with bitterness, but rather with courage, requires endless patience and infinite hope.

Although the script of the film doesn’t spell it out, Mary’s story emphasises that the absence of painful memories is in itself experienced as a painful loss. What’s more, it shows that, without the memory of the suffering which we have inflicted on others, and which others have inflicted on us, we are incapable of moral growth. Thanks to the knowledge of the past, Mary is able, this time around, to resist having an affair with a married man. Just so, the final scene of the film, which sees Joel and Clementine vow to renew their relationship, is hopeful not in spite of the fact that they have regained the memory of the ways in which they hurt each other in the past, but precisely because of it.

Accepting suffering and holding it in our hearts, not with bitterness, but rather with courage, requires endless patience and infinite hope. But that is what we were made for. Each one of us is called to endure pain in imitation of Christ, and, out of that pain, to discover a greater capacity for sacrificial love. We make meaning out of pain: that’s what human beings do.

The very last lines of Eternal Sunshine of the Spotless Mind perfectly express the fruits of this Christ-like acceptance. As Joel reassures Clementine that he can’t see anything he doesn’t like about her, she expresses her doubts and anxieties: ‘But you will! But you will.’, she repeats, ‘You know, you will think of things. And I’ll get bored with you and feel trapped because that’s what happens with me.’ Joel and Clementine look at each other, and, after a pause, they simply say to each other: ‘Okay’. Their ‘okay’ is not an indication that they are doomed to repeat old mistakes. Rather, it signals a new choice: this time, when their relationship becomes difficult, they won’t just run away; this time, they will face discomfort, heartbreak, and disappointment, armed with the knowledge that seeking a sense of permanence by loving another person completely is an inherently valuable pursuit. In accepting the most traumatic parts of our past we grow closer to God; and in bravely deciding to look ahead to the future with hope, we catch a glimpse of the unadulterated joy which we will finally experience in God’s eternity.
