Psychopathy, Altruism and the Gift of Life: Neuroscience with Dr. Abigail Marsh | Patient Stories | Organ Donation | Medical Experts

In this episode, Dr. Marsh explains the neuroscience of altruism, from the role of the amygdala to genetic influences on empathy. Through Dr. Marsh’s donor stories and research insights we explore the spectrum of altruism and psychopathy. She reveals how the amygdala, the brain region tied to emotional responses, plays a pivotal role in altruistic behavior. Remarkably, research shows that altruistic kidney donors often have larger amygdala sizes compared to the average person.

Dr. Marsh also reveals the genetic factors that shape empathy and altruistic tendencies, while challenging the misconception that altruism is irrational or abnormal. She contrasts the media’s frequent focus on negative aspects of human nature with the lived experiences of donors, who describe profound feelings of honor and fulfillment after giving the gift of life.

Throughout the conversation, personal stories from living organ donors underscore the importance of community support for both donors and recipients. Dr. Marsh emphasizes the power of education and awareness to dispel myths about donation and highlights that altruism is not only a natural human trait but also one that can be nurtured and encouraged in all of us.
