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.

Marsha de Cordova: the personal experiences driving her passionate politics

“What disabled people need is assistance to live, not to die.”

Robert is a journalist at the Financial Times.

 

A woman wearing a red jacket stands formally beside an office stair case.

When Marsha de Cordova talks about most issues relating to her work as the Member of Parliament for Battersea, in south London, she sticks to the standard position of her Labour party. Meeting at her constituency office by the busy Clapham Junction railway station, she dutifully defends her party’s government, elected last July. She points to ministers’ work to reform planning and improve renters’ rights as evidence they are making progress. 

But when conversation turns to the Assisted Dying Bill currently going through parliament, her tone becomes unmistakeably more urgent and her passion more obviously personal. 

The strong feelings mark de Cordova out as one of a group of Labour MPs who have been spurred by personal experience and, in many cases, religious conviction to oppose the Assisted Dying Bill introduced by a colleague, Spen Valley MP Kim Leadbeater. While the legislation is a private member’s bill without official government support, it has been widely seen as reflecting the views of Prime Minister Keir Starmer. 

De Cordova, who is Black, expresses similarly trenchant views about the government’s rhetoric on immigration. She is also a strong supporter of rapprochement with the European Union. 

However, her views on assisted dying – informed partly by being a committed Christian – are particularly forcefully expressed. She answers tersely, “No, I’m not”, when asked if she is happy about the political capital the new government has expended on the Assisted Dying Bill. She adds that she voted against it at second reading, the first parliamentary vote on a bill. She intends to oppose it again at third reading, before it passes to the House of Lords. 

“We didn’t need to expend so much capital on it,” de Cordova says. “The aim now has to be to ensure the bill doesn’t pass third reading.” 

Many of the Labour MPs who have opposed the legislation have cited religious objections. In the Cabinet, they include health secretary Wes Streeting and foreign secretary David Lammy, both Christians, and justice secretary Shabana Mahmood, a Muslim. 

De Cordova also links her opposition to her disability. De Cordova is registered blind because of nystagmus, in which the eyes repeatedly move involuntarily, disrupting vision. There have been fears assisted people could come under greater pressure than others to seek assisted death. 

“As a disabled woman, I’m incredibly concerned,” de Cordova says. “What disabled people need is assistance to live, not to die. That should be our government’s priority.” 

“My faith is an integral part of who I am. It really is part of my values, my beliefs, my politics.” 

The assisted dying fight has garnered unusual levels of publicity for the Battersea MP, who entered parliament seven years ago when barely expecting to do so. De Cordova, now 49, was serving as a Lambeth borough councillor when the 2017 snap general election was called and decided to seek the Labour nomination for Battersea, then held by the Conservatives. 

The seat was one of several Conservative seats in pro-Remain areas that fell to Labour’s surprisingly strong showing in the election in the wake of the 2016 Brexit referendum. 

“No one really thought I could win here,” de Cordova says. “Obviously, Brexit I would say played a role in that I’m a strong Remainer.” 

De Cordova increased her majority in 2019 and last year’s general election. She sees strong continuities between serving as an MP and her previous role in the charity sector. She had been working when elected as the engagement and advocacy director for the Thomas Pocklington Trust, which supports blind and partially sighted people. 

“I didn’t grow up wanting to be a politician,” de Cordova says, of her upbringing in Bristol. “I’ve always had the desire to be making a difference. All of my work before becoming a politician centred around that – being that voice for the voiceless.” 

She links her work to her faith. She became a Christian in her late 20s and now attends Holy Trinity Clapham. The church is famous as the spiritual home of William Wilberforce and the “Clapham Sect” of early 19th century campaigners against the slave trade and other social evils. 

Her faith has led to her appointment as second church estates commissioner – the liaison between parliament and England’s established church, who answers questions in the Commons on behalf of the church. 

“My faith is an integral part of who I am,” de Cordova says. “It really is part of my values, my beliefs, my politics.” 

It becomes clear speaking to her that her objections to the policies of the government – and the Assisted Dying Bill, which many of her party colleagues support – are clustered around areas involving challenges to fundamental rights. 

She objects to the Assisted Dying Bill because she sees it as part of a steady erosion of disabled people’s rights. 

“The issue will have a hugely, hugely disproportionate impact on disabled people,” she says. “That, for me, is a no-no.” 

Provision for disabled people was “hollowed out” under the last Conservative government, she says. 

“That, for me, will always be the issue,” de Cordova says. “I want to campaign and fight for full equality for us.” 

She also views immigration issues through the prism of immigrants’ rights. 

Asked if she wishes the government took a less hostile tone on the issue, she replies: “From my perspective, when I think about immigration, I tend to think about it in a compassionate way.” 

She calls for the establishment of “safe routes” to ensure people fleeing persecution can claim asylum from outside the UK, without making dangerous Channel crossings. The government has shown no signs of introducing such rights. 

“Let’s think about immigration in a positive way,” de Cordova says, adding that her grandparents were immigrants to the UK from the Caribbean. “The Tories and the right have always tried to portray it as a negative. It’s not always a negative.” 

For de Cordova, the unglamorous role of church estates commissioner forms part of that pattern of advocating for the voiceless. 

The job entails dealing with every aspect of MPs’ questions about church life, including the status of historic buildings and other less obviously morally important questions. 

However, de Cordova, who was appointed a month before publication of the Makin Report on the church’s handling of abuse by John Smyth, is clear the church has urgent problems to resolve. 

The Makin Report has to be a “turning point”, she says. 

“I understand steps are being taken to address the challenges,” de Cordova says. “They need to set out over time how they’ll ensure such abuse never happens again.” 

The campaigning approach is part of de Cordova’s wider philosophy. She says she has faced many challenges as a result of her disability and tried to overcome them. 

“I want to ensure that I can break down the barriers for people coming after me, so that people don’t have to face those same experiences,” she says.
