The abstract of an article found here states that “studies indicate that heart transplant recipients may exhibit preferences, emotions, and memories resembling those of the donors, suggesting a form of memory storage within the transplanted organ. Mechanisms proposed for this memory transfer include cellular memory, epigenetic modifications, and energetic interactions. Moreover, the heart’s intricate neural network, often referred to as the ‘heart brain,’ communicates bidirectionally with the brain and other organs, supporting the concept of heart-brain connection and its role in memory and personality.” The article is a nice example of dramatic research results that can serve a target for critical thinking about memory mechanisms as well as about research design and methodology.
