Through the use of single-neuron recording, reversible inactivation of subsets of neuronal populations, and computer simulations, we have discovered a crucial component of the brain mechanism for generating microsaccades. These results provided the first neuronal substrate for understanding the links between microsaccades and visual attention that we and others have observed in humans starting ca. 2002.
One of our long-term goals is to understand the brain mechanisms subserving microsaccade generation as well as the mechanisms allowing internal-monitoring of these movements. We are also interested in learning how fixational eye movements in general may help us further understand the nature of covert visual processing in the brain.
