From vegetarians craving meat to adjustments in sexual choice, some organ transplant sufferers report adjustments to their character reflecting these of the organ donor.
A 2024 examine claims to problem “conventional views of memory and identity” by suggesting organs carry recollections and feelings and that the findings increase “ethical and philosophical questions” about transplantation.
In medical historical past, although, each are already acquainted themes. Doctor J. Andrew Armour argued that the center holds recollections and emotions in 1991. Neither is there something new about suggesting organ transplants increase moral and philosophical questions – they have been controversial since their inception within the Fifties.
The examine’s authors don’t have interaction with the cultural histories of organ donation, or its ethnic, spiritual and historic contexts. With out an understanding of those, analysis – and media protection – can perpetuate Frankenstein-style horror myths about transplantation, already an emotive and moral minefield.
For many years, researchers have studied whether or not recollections and feelings may linger within the coronary heart, and histories of drugs and emotion present why the query is vital. It’s the coronary heart, the centre of the self – valued in all cultures from historic Egyptians’ coronary heart weighing to present-day Valentine’s Day playing cards – that speaks emotional truths.
I am a historian of drugs, emotion and the physique. In 2010, I wrote Issues of the Coronary heart: Historical past, Medication, and Emotion, a historical past of the emotional, bodily and non secular significance of the center. My analysis exhibits that, earlier than the emergence of scientific medication, the center was thought of the centre of emotion and reminiscence.
English doctor William Harvey popularised the circulatory blood mannequin in 1628 – first theorised by Thirteenth-century Arab doctor Ibn al Nafis. This changed Galen’s 2,000-year-old concept that blood was produced within the liver and burned by the physique.
As soon as the center was understood to be a pump, the mind was promoted to the centre of thought, reminiscence and emotion – helped by René Descartes’ whose 1949 e-book, Passions of the Soul, explored the connection between thoughts and physique. Regularly, this secularised view of the center turned widespread – the mechanical pump mannequin remains to be taught in colleges.
And, whereas few cardiologists imagine the center – the centre of a fancy chemical system – is an easy organ, most favor not to consider the center because the seat of the soul.
“How then”, one well-known coronary heart transplant surgeon requested me, “could I cut it out of a man’s body?”
Not all organs are emotionally significant. I analysis face transplants – faces are much more emotionally important than hearts. Faces and hearts talk emotions: faces convey expression whereas hearts beat quicker when anxious or in love.
It is tough to get sentimental in regards to the spleen, a kidney, or a small bowel. So, then, it is not all organs that carry recollections and meanings, however hearts, particularly.
However what about xenotransplants, when non-human tissues, cells and organs are used to deal with people. Will recipients of genetically modified pig hearts bear in mind their time on the trough?

There is growing evidence to suggest cellular memory exists in some form – that is, cells retaining information about past events that are stored outside of the brain. And Bessel van der Kolk’s idea that the “physique retains the rating”, while not scientifically proven, is familiar in trauma research, including intergenerational research of slavery and holocaust survivors.
Nonetheless, the 2024 examine supplies solely a abstract of current work, a few of which includes simply ten sufferers, with unclear findings. The examine additionally cites earlier, largely anecdotal accounts that coronary heart transplant recipients would possibly expertise a change in meals, music and even sexual preferences.
For instance, Claire Sylvia craved hen nuggets, similar to her donor. However would not the reminiscence of hen nuggets be lodged within the intestine? The intestine is ever extra vital in understandings of feelings and psychological sickness, together with schizophrenia.
Given there’s additionally a well-established gut-brain axis – a two-way communication system between the mind and the gastrointestinal tract – possibly it is a dialogue much less in regards to the potential for organ transplants to vary sufferers’ personalities and extra in regards to the limitations of scientific medication that divides the thoughts and physique up so neatly and so problematically.
Cultural context
Reminiscence and feelings will not be merely organic phenomena, however pushed by environments, experiences and relationships. They, like beliefs in regards to the coronary heart, are knowledgeable by cultural contexts.
In Thailand or Japan, for example, there may be extra pronounced medical curiosity within the non secular coronary heart – Japan would not recognise mind demise till 1985 because of this. So, cross-cultural comparisons are wanted to grasp how far narratives of reminiscence switch in coronary heart transplantation are common.
And the examine would not focus on the complicated cultural and psychological explanation why folks would possibly really feel they modified tastes or attitudes after an organ transplant. Coronary heart transplant surgical procedure is main surgical procedure that may invoke emotions of concern, gratitude, hope and longing, and post-traumatic stress dysfunction in addition to survivor guilt.
One bride-to-be discovered her father’s coronary heart recipient as a result of she needed him to stroll her down the aisle. Sufferers can overhear conversations and skim between the strains, whereas immunosuppressants can have a transformative impact on sufferers’ emotions.
So, there are numerous explanation why these distinctive tales of character change would possibly exist. And they’re distinctive – an Austrian examine of 47 coronary heart transplant recipients, discovered that 79% reported no change.
We’d like extra debates about organ donation – and the thoughts and physique cut up in trendy medication – however specializing in probably the most urgent points. Akin to, why there is no such thing as a actual join-up in psychological and bodily healthcare, and easy methods to change that.
Public debates about whether or not knowledgeable consent is working, and whether or not xenotransplantation (utilizing animal elements) and organogenesis (rising organs) are the way in which forward. One other dialogue available is about how far hospital duties to transplant sufferers prolong past the working theatre, particularly within the US context of privatised healthcare.
Proper now, I fear about what is going to occur to UK transplant sufferers who might be equally crushed by costly drugs if we do not save the NHS. We’d like these debates not solely to assist rigorous moral requirements and evidence-based analysis, but additionally, amid a lot misinformation about science, to keep away from media sensationalism.
