Functional connectivity

Whereas initial stimulus processing can be accomplished in primary sensory areas, such as the visual (see areas I and II in the figure below), somatosensory (III) and auditory (IV) cortex, sensory integration and conscious perception requires information transfer and communication between distant cortical areas (black arrows). Synchronized neural oscillations represent a mechanism to form functional connectivity networks, in which information can be transferred. In our research, we examine how information transfer and higher cognitive processes are reflected in neural networks and how cognitive and emotional processes influence perception.

For conscious perception, information that is initially processing in specialized sensory areas has to be transferred across a larger functional network.
