Adaptive neural mechanisms of self face recognition after face transplantation.

ABSTRACT: The study aims to investigate the behavioral and neural responses of a face transplant patient (FTP) to his pre-operative and post-operative faces. For this purpose, a control group (N = 15) and a single FTP were presented images of their past face, present face, and other unfamiliar faces and asked to identify whether these faces belonged to them or not. During the task, electrophysiological and behavioral responses were recorded. The FTP exhibited higher N170 amplitudes for his past face compared to the control group, suggesting increased visual processing due to its distinctiveness. N250 latency was shorter for his past face, indicating a profoundly ingrained self-identity. P300 amplitudes to his present face were significantly higher, potentially reflecting cognitive adaptation to his
