摘要：
This invention relates to methods and systems for determining network connections. It is particularly, but not exclusively, related to methods and systems for determining network connections in sparse networks, and has particular application to EEG data. An aspect of the invention provides a method for identifying, in a network of interacting nodes simultaneously producing signals, connections between said nodes and of estimating connection coefficients between nodes identified as connected which includes the steps of setting to zero connection coefficients where the calculated coherence or partial coherence is below a first predetermined threshold and subsequently setting to zero connection coefficients where the estimated connection coefficients are below a second predetermined threshold, and then re-estimating the connection coefficients for the combinations of nodes for which the connection coefficients have not already been set to zero.
