Abstract
The purpose of the study was to investigate the relationship between human cognitive processes and eye movements during inspection of images using methods of ultrafast functional magnetic resonance imaging (fMRI) and eye tracking. We conducted two series of experiments in which participants saw pictures of faces and houses. Statistical processing of the fMRI data showed that visual fixations on different objects in the context of different tasks lead to different patterns of cortical activation, and reconstructed BOLD signal responses show important information about the task context of individual fixations on viewed objects.
