A closer look at goal-directed eye and hand movements
Humans continuously make saccadic eye movements to see their surroundings with the high precision of the fovea. Each saccade shifts the image on the retinas, such that the visual system needs to integrate blurry peripheral views of objects with their high-resolution equivalents once brought into the fovea. Understanding how this seamless integration is achieved is critical for theories of human perception. The EU-funded project PremotorPerception combines psychophysical protocols that enable a continuous assessment of visual sensitivity throughout the visual field with transcranial magnetic brain stimulation to investigate the role of specific brain areas underlying these modulations. We assess dynamic modulations of visual processing before saccades and goal-directed hand movements that enable continuous perception as the eyes move.
