In this presentation, I refer to a paper (Lopes, 2019) in which I discuss the idea of personhood, or one's sense of self, in relation to advanced meditators in the Tibetan Buddhist tradition. Focusing on accounts of laboratory experiments on two advanced meditators, I look at the circulation of cultural products derived from these experiments in popular media to explore how they can impact our understandings of what it means to be human and point to the idea of the plasticity of personhood .
