Dynamic visual cortical connectivity analysis based on functional magnetic resonance imaging.

ABSTRACT:

Background

Studies of brain functional connectivity (FC) and effective connectivity (EC) using the functional magnetic resonance imaging (fMRI) have advanced our understanding of functional organization on visual cortex of human brain. The current studies mainly focus on static or dynamic connectivity, while the relationships between them have not been well characterized especially for static EC (sEC) and dynamic EC (dEC), as well as the consistency characteristics of changing trend of dFCs and dECs, which is of great importance to reveal the neural information processing mechanism in visual cortex region.

Method

In this study, we explore these relationships among several subareas of human visual cortex (V1-V5) by calculating the connection intensity and information flow amo
