Under most naturalistic situations, attentional selection is achieved by moving our eyes around the environment, bringing objects of interest to the centre of the visual field where acuity is highest. This relationship between eye movements and attention has been the subject of much debate in psychology and neuroscience. Evidence from psychophysical and neurophysiological studies has shown that saccade preparation is often accompanied by shifts of visual attention. My project aims to investigate the neural dynamics that underpin perceptual selection during saccade preparation. More specifically, I will investigate the brain dynamics associated with presaccadic shifts of attention in human participants using magnetoencephalography (MEG) and in non-human primates using large-scale recordings across multiple brain regions.
