[The spatial ordering of the brain electrical processes as an index of its functional organization]

Analysis of constraints, which are imposed on correctness of conclusions drawn from the studies of the spectrum-correlation model of cortex electrical activity, and necessity of enlarging interaction forms which have to be studied, brought to development a new index for estimating spatial order of cortex electrical processes. This index and the technique were called "multiple entropy" (ME). The algorithm of calculating ME and its properties are discussed. The results of studying spatial structure of cortex electrical processes by estimating their spatial synchronization and ME were compared. It was shown that these approaches complemented each other. Using both these techniques in combination gives more complete picture of integration of cortex processes.
