| Abstract/Results: | ABSTRACT:
A plethora of research has investigated the neural basis of the ability to recognise one’s current facial appearance in photographs or mirrors. However, one important question has not previously been examined; how are images of one’s past facial appearance processed in the brain when they are also recognised as “me”? To examine this question, we used fMRI to investigate brain activity as participants viewed images of themselves, morphed with images of a personally familiar other. The images were morphs between the participants’ and the familiar others’ current facial appearances or their childhood appearances. The participants performed a self-other judgement on morphed pictures that contained 0%, 20%, 40%, 60%, 80% or 100% “self”. We analysed the fMRI data parametrically, to examine activity that covaried with the percentage of “self” present in the stimuli. Activity in areas involved in body-ownership and memory retrieval varied with the amount of the participants’ childhood face in the images, but not the amount of the participants’ current facial appearance. We also found that activity in a network of face-selective, but not self-face selective areas varied with the amount of current self in the stimuli and not the amount of childhood self. We argue that a representation of one’s current facial appearance is maintained and updated in networks that process all faces. In contrast, representations of one’s past facial appearances are stored in memory and then are re-experienced as a part of one’s own body, allowing them to be recognised as one’s own.
