Dynamic Communication and Connectivity in Frontal Networks

Show Summary Details


The brain is a dynamic, growing, changing organ consisting of many interconnected brain regions that communicate to give rise to a unified sense of self and cognition. The prefrontal cortex plays a critical role in cognitive processes including attention and working memory. Brain lesions—such as from stroke—lead to cognitive deficits, however these deficits can recover over time. This chapter examines the role that neuroplasticity plays in the recovery of cognitive functions and it discusses the nature of the dynamics of network communication in cognition. These phenomena highlight the importance of distributed networks in higher cognition and pose difficulties for cognitive functional localization

Keywords: prefrontal cortex; functional localization; stroke; recovery; neuroplasticity; lesion; networks; attention; working memory
