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.

Ludwig’s clues to the answers we long for

Puzzles preserve a fully realised truth in the clue, and, if we are willing to persevere, we will be rewarded.
Two TV characters, a man and a woman, stand in front of a crossword cover walls of a room.

The BBC have scored a bingeable hit with new comedy-drama Ludwig, starring David Mitchell as a maladroit puzzle-setter who is roped into a rather fabulous whodunnit. It involves his missing twin, a police detective whom he must impersonate in order to chase the trail of the disappearance.  While on the case he solves a few other conundrums, giving the show many intriguing, if knotty, narrative threads.  

It is not the first-time crossword setting and detective work have gone hand in hand. One of the very first cryptic crossword setters - the ‘grandfather’ of the genre - was Edward Powys Mathers, who also dashed off a mystery thriller, Cain’s Jawbone in 1934. The novel was provided to readers in the wrong order, with the simple but infuriating challenge to reconstruct the right sequence of pages based on maddeningly subtle internal clues. Despite offers of a cash prize, virtually no solutions were submitted.  

Such is the dilemma of a cryptic crossword setter - when is clever too clever? Puzzles can appeal so much to our pride; our desire to be part of an ‘in-group’ which understands the highbrow references to opera, Latin oratory, and cricket slang. Those who can outwit them are part of an elite rank. The Telegraph crossword of 13th January 1942 was used as an exercise to recruit for the ENIGMA codebreaking unit. Indeed, when Mathers all but invented the idea of a fully cryptic crossword in the Saturday Westminster Gazette in 1924, his challenges bore the banner ‘Crosswords for Supermen’.  

There is fundamental connectedness behind the world, and working on the presumption of such a unity allowed him to collect ideas and references from across the globe and throughout all history to form his tricksy clues. 

I’ve often started out on a cryptic crossword, hoping to discover that I am one such genius, only to bitterly give up shortly afterwards, irritated that I don’t have that instant ability to see the solutions. I stare at the riddle, wanting to be one of those people who can naturally recall information, connect ideas, or see what has been hidden in the tortuous clue. Surely the appeal of a show like Ludwig is that it gives us an aspirational glimpse at the peak of human mental prowess, even if Mitchell’s wannabe inspector is a little socially awkward. He still possesses a penetrating gaze that looks through the surface of things, to see what no one else can. He is one of those ‘supermen’ - beholden to no one, able to uniquely see the way things are all by himself.  

And yet, when Edward Powys Mathers died in 1939, he was referred to in his Observer obituary not as a kind of lone snobby genius, but “the gentlest of men… a saint”. It’s appropriate, as crosswords have long been a curiously churchy phenomenon: in the small list of great UK cryptic writers, two have been Anglican priests (Revd John Graham, known as Acaucaria, and Revd Canon A. F. Ritchie, or Afrit). Even Mathers’ fondness for Biblical allusions in his clues “led many to endow him with ecclesiastical rank” as Roger Millington’s book on Crosswords put it. Christian faith, because it is a religion built on the idea that God is with us in flesh, invites us to pay attention to the world around us. The world is not something to escape from, but is rather the place that, in Jesus Christ, God has come to meet us in. It makes you want to understand time, place, and culture, to better understand the God who has spoken through them, and given them meaning and destiny. In reference to this way of seeing things, Mathers was spoken of as a ‘catholic’ thinker in his obituary. This did not mean his church affiliation, but rather an instinct for seeing how everything is part of a greater whole. There is fundamental connectedness behind the world, and working on the presumption of such a unity allowed him to collect ideas and references from across the globe and throughout all history to form his tricksy clues.  

There is also a negative hint in this obituary clue, ‘catholic’. Crossworders work under a nom de plume (David Mitchell’s character John for instance, who goes by ‘Ludwig’). And while Mathers was indeed a generous, open-minded man, he sealed his reputation for difficulty by adopting the pseudonym ‘Torquemada’, in reference to a former Grand Inquisitor of the Spanish Inquisition. So, if Christians are alive to the interconnectedness of all things, we also have a reputation for the institutional guarding of those very mysteries. History shows believers have tortured those who do not come to their idea of what the answer is; indeed, they have set the questions for too long, in the eyes of many hostile to the faith.

Puzzles preserve a fully realised truth in the clue, and, if we are willing to persevere, and learn a new way of seeing, and of paying attention, we will be rewarded. 

But this is the tension that crosswords offer us - a very authentically Christian way to think about the way God spells things out for us which does not rely on a stark binary of ‘true’ or ‘false’. He reveals things like a puzzle; slowly, and cryptically. Some might fairly object to this comparison, on the grounds this would make God too ‘out there’ - far away from the intimate father that Jesus bids us address so familiarly. Does it make God too remote and enigmatic to say he is setting riddles for us? But actually, a puzzle does not deceive us, like a mask does. Puzzles preserve a fully realised truth in the clue, and, if we are willing to persevere, and learn a new way of seeing, and of paying attention, we will be rewarded. The answer is there, reaching out to us, if we only commit ourselves humbly to receiving it. It may cost us much effort and time. It may require us to learn things afresh. But this is part of the joy of trying to see, as St Paul puts it, "the mystery hidden for ages in God, who created all things”.  

Jesus himself spoke in parables, very much like cryptic clues. But this was no elitism, designed to cut out those without the high IQ of David Mitchell’s ‘Ludwig’. Arrogant intellect or love of one’s own status is, for Jesus, just as much a bar to those seeking a solution, because to find the answer requires a certain submission - a discipline - to see things as the puzzle-setter sees them. If we proceed only to do things our way, we remain blind: seeing we do not see, and hearing we do not hear, nor do we understand.
