Neural Grafting: Implications for Personal Identity and Personality

It is often suggested that advances in neurosciences will force us to re-think our customary notions of personal identity and personality. In this paper, we study a number of philosophical positions on these notions, especially in connection with mentally degenerative illnesses and neural grafting. We conclude that while the possible future treatments are likely to change the personalities and personal identities of patients, these changes will not pose any new challenges to the notions of personal identity and personality.
