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 “typical views of reminiscence and id” by suggesting organs carry recollections and feelings and that the findings increase “moral and philosophical questions” about transplantation.
In medical historical past, although, each are already acquainted themes. Doctor J. Andrew Armour argued that the guts 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 Nineteen Fifties.
The examine’s authors don’t interact 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 medication and emotion present why the query is necessary. It’s the coronary heart, the centre of the self – valued in all cultures from historical Egyptians’ coronary heart weighing to present-day Valentine’s Day playing cards – that speaks emotional truths.
I am a historian of medication, emotion and the physique. In 2010, I wrote Issues of the Coronary heart: Historical past, Drugs, and Emotion, a historical past of the emotional, bodily and non secular significance of the guts. My analysis reveals that, earlier than the emergence of scientific drugs, the guts was thought-about 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 principle that blood was produced within the liver and burned by the physique.
As soon as the guts 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 guts grew to become widespread – the mechanical pump mannequin continues to be taught in faculties.
And, whereas few cardiologists consider the guts – the centre of a posh chemical system – is a straightforward organ, most choose not to consider the guts because the seat of the soul.
“How then”, one well-known coronary heart transplant surgeon requested me, “may I minimize it out of a person’s physique?”
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 troublesome to get sentimental concerning the spleen, a kidney, or a small bowel. So, then, it isn’t 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 may be rising proof to counsel mobile reminiscence exists in some type – that’s, cells retaining details about previous occasions which are saved exterior of the mind. And Bessel van der Kolk’s concept that the “physique retains the rating”, whereas not scientifically confirmed, is acquainted in trauma analysis, together with intergenerational research of slavery and holocaust survivors.
Nevertheless, the 2024 examine offers solely a abstract of present work, a few of which entails simply ten sufferers, with unclear findings. The examine additionally cites earlier, largely anecdotal accounts that coronary heart transplant recipients may expertise a change in meals, music and even sexual preferences.
For instance, Claire Sylvia craved rooster nuggets, similar to her donor. However would not the reminiscence of rooster nuggets be lodged within the intestine? The intestine is ever extra necessary 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 – perhaps this can be a dialogue much less concerning the potential for organ transplants to vary sufferers’ personalities and extra concerning the limitations of scientific drugs 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 concerning the coronary heart, are knowledgeable by cultural contexts.
In Thailand or Japan, as an illustration, there’s extra pronounced medical curiosity within the non secular coronary heart – Japan would not recognise mind dying 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 does not focus on the complicated cultural and psychological explanation why individuals may 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 browse between the strains, whereas immunosuppressants can have a transformative impact on sufferers’ emotions.
So, there are a lot of explanation why these distinctive tales of character change may 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 break up in fashionable drugs – however specializing in essentially the most urgent points. Reminiscent of, why there isn’t a actual join-up in psychological and bodily healthcare, and how you can 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 tasks to transplant sufferers prolong past the working theatre, particularly within the US context of privatised healthcare.
Proper now, I fear about what’s going to occur to UK transplant sufferers who will probably be equally crushed by costly drugs if we do not save the NHS. We’d like these debates not solely to help rigorous moral requirements and evidence-based analysis, but additionally, amid a lot misinformation about science, to keep away from media sensationalism.
