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.

The utter humanity of Wallace and Gromit

Choices in front of and behind the camera tame technology.
A still from a claymantion film shows three characters, Wallace, Gromit and a robot garden gnome marching out a garden shed.
AI: here to help.
Aardman Animations.

In 1993, Aardman Animations released Wallace & Gromit: The Wrong Trousers. It follows hapless inventor Wallace and his long-suffering dog Gromit as they rent out their spare room to a penguin, Feathers McGraw, who is subsequently revealed to be a master criminal, narrowly pipping Anthony Hopkins’ Hannibal Lecter and Javier Bardem’s Anton Chigurh to the title of cinema’s most sinister villain. (Trust me: you will never look at a red rubber glove the same way after The Wrong Trousers). 

At the film’s climax, perpetual good-boy Gromit chases McGraw through the house via a series of increasingly convoluted model railway tracks, even as he has to build the very tracks he’s riding on. There is a strong argument to be made that it is best scene in cinematic history.  

Fast forward to Christmas, 2024, and Wallace and Gromit: Vengeance Most Fowl is shown on BBC One on Christmas Day. It tells the story of Feathers McGraw – who has lost none of his quiet menace – plotting revenge on the eponymous duo, this time by taking over a series of technologically advanced garden gnomes Wallace has invented.  

While nothing in Vengeance Most Fowl tops the train chase from The Wrong Trousers – indeed, how can one improve on perfection? – it is another magnificent addition to the Wallace and Gromit oeuvre.  

Moreover, it is a remarkably prescient tale about the dangers of technology, and the beauty of humanity. It is the perfect antidote to much of modern cinema and almost single-handedly restored by faith in film as an artistic medium. Vengeance Most Fowl is such a success because it oozes humanity in every single frame. However, this humanity appears most clearly in three distinct ways.  

First, in its story. The inciting MacGuffin of Vengeance Most Fowl is the new garden gnomes Wallace has concocted. Feathers McGraw takes control of Wallace’s gnomes by hacking into its software and switching it from ‘good’ mode to 'evil’ mode. (Like everything in life, this is a joke The Simpsons got to first: in 1992’s “Treehouse of Horror III,” Homer accidently buys Bart a Krusty the Clown doll accidently set to ‘evil’ mode rather than ‘good’ mode.) 

Vengeance Most Fowl offers a more nuanced take on technology than most. It’s neither straightforwardly good nor straightforwardly bad; it depends entirely on the user. We see the benefits of the gnomes as they help people with their gardening. But put them in the hands of the wrong person – or penguin – and they become tools for evil. Vengeance Most Fowl is not an anti-technology film, then, but is realistic about the fact that some humans – and, indeed, penguins – will inevitably seek to use technology for nefarious ends. 

Second, in its voice acting. Vengeance Most Fowl is the first Wallace & Gromit film released following the death of long-standing Wallace voice actor Peter Sallis. It is genuinely remarkable, then, that no AI was used by Aardman to replicate his voice. Instead, this is left to Ben Whitehead and the results are certainly worth it. 

Where many film studios or production companies would have used technology to offer a ‘fake’ Sallis performance – think Peter Cushing in Rogue One: A Star Wars Story, for example, or even the use of AI to reconstruct John Lennon’s voice for the lost Beatles single “Now and Then” – Aardman did not. Instead, they made a very conscious decision to have Whitehead offer a deeply human performance as Wallace. When (SPOILER ALERT) at the end of the film Wallace tells Gromit that he can live without inventing, but he can’t live without his dog, the emotional pay-off is so genuine because it is real. Because it is a thoroughly human moment. 

Third, in its cinematography. Claymation is a medium only adopted by artists who hate themselves. That’s the only reason I can think for making an entire film using such a slow, tedious process. It is also a deeply human art form. It is the result of tens of thousands of hours of painstaking and repetitive work. It is yet another conscious choice by the team at Aardman to create something that is thoroughly and unmistakably human. 

All of this, I think, says something about how Wallace & Gromit manages to feel like such a breath of fresh air. It has not been committee-d to death, or market research-ed into beige-ness. It is full of stupid little jokes (like Gromit reading Virginia Woof) and localised references (“Yorkshire Border: Keep Out!” followed by “Lancashire Border: No, Your Keep Out!”).  

The cost of making Wallace & Gromit films is too costly for them to be cheap, mass-produced disappointments churned out at an increasing rate of knots. They are lovingly hand-crafted works of art and, given the current state of much cinema and TV, they are nothing short of minor miracles.  

Wallace & Gromit is an utterly human series of films. It isn’t perfect. And that’s what makes it perfect.
