Abstract: We investigated if the fusiform face area (FFA) and the parahippocampal place area (PPA)contain a representation offixation sequences that are typically used when looking at faces orhouses. Here, we instructed observers to follow a dot presented on a uniform background.The dot’s movements represented gaze paths acquired separately from observers looking atface or house pictures. Even when gaze dispersion differences were controlled, face- andhouse-associated gaze patterns could be discriminated by fMRI multivariate pattern analysisin FFA and PPA, more so for the current observer’s own gazes than for another observer’sgaze. The discrimination of the observer’s own gaze patterns was not observed in early visualareas (V1–V4) or superior parietal lobule and frontal eyefields. Thesefindings indicate a linkbetween perception and action—the complex gaze patterns that are used to explore facesand houses—in the FFA and PPA.
