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.

Shorter TED Talks are not the only way to learn

As education and entertainment blend, get ready for the unexpected.

Are you going to make it to the end of this article? I'm aware, dear reader, that much of the responsibility for this is down to me. But spare a thought (or maybe an extra five seconds before returning to Instagram) for those wanting to communicate something of substance in today's abbreviated age. Take TED talks, for instance. 

The already bite-sized format has had another chunk gorged out of it. Elif Shafak, a Turkish-British novelist needed to trim her TED talks from 19 to 13 minutes. In the view of The Times' editorial,

'Packing the world’s knowledge into the time it takes to heat a pizza might seem ambitious. Sadly, it now appears to be beyond the patience of those thirsting for enlightenment.' 

It's worth us recognising that education and entertainment have blended in our consciousness ('E' in the TED acronym standing for 'entertainment'), with our era's pastime being consuming more information. And if we consider this, are our attention spans truly squeezed beyond the point of no return? I'm not so sure. We are also in the age of bloated films and slow-burn series. If we are invested in the entertainment we want, then we will cope. In fact, many theatres are doing away with intervals. The interval is a relatively modern invention. Susanna Butler writes that in Shakespeare's day not only did people have longer attention spans, but they could roam freely during the play. I suspect not many were distracted for long. For the information or entertainment provider, there's no excuse for being boring, or unnecessarily verbose. 

But if we free ourselves from being dependant on dopamine, and take the longue durée of our lives, we open ourselves to learning in a new way. That's not to say that we should give up an ever-present expectation for the next hit of knowledge. 

This is what it means when Christians are referred to as disciples: the word to describe an apprentice or student of their master. These disciples, to Rowan Williams,  

'take it for granted that there is always something about to break through from the Master, the Teacher, something about to burst through the ordinary and uncover a new light on the landscape.'  

This is the kind of expectation that doesn't front-load an Instagram reel with its best content in the first three seconds. It might be a quaint analogy, but as Williams writes, this has more in common with ornithologists. 

 'The experienced birdwatcher, sitting still, poised, alert, not tense or fussy, knows that this is the kind of place where something extraordinary suddenly bursts into view.' 

I'll keep this as short as I can. But any hope of discipline in attentiveness must be sparked by the sight of the one who has infinite attention for us. And all the time in - and out of - the world.
