Non-invasive neurotechnology for coordinated control of vision via visual networks

Scientists at the University of Geneva (UNIGE) have developed an eye-tracking system enabling surgeons to operate on patients more effectively through a novel kind of non-invasive neurotechnology. This new approach is to be published in Nature Communications.

Seeing is an evolutionary skill that humans derive from vision. Like a spectre that signals us to occupy its space our vision allows us to navigate to find our way home and to impress people around us. But the human brain has an extraordinary capacity for anticipating its environment and scene focus thus that nearly everything is possible through visual perception.

The vision-control system of the brain consists of two levels of brain networks: Decision and Reconfigurable. Decision is responsible for initiating the controls that allow us to adapt to the sensory environment and the Reconfigurable network ensures that our visual perceptions remain in sync with our general perception of the environment (the visual network) to ensure maximal efficiency.

We have identified for the first time the precise regions of the visual cortex that contain biologically relevant information for visual perception. To our knowledge this is the first demonstration of structural and functional organization of the visual cortex.
