Measure of the correlation between brain activities: a methodological approach.
This paper is a short review of the work done on methods of measuring nerve activity. 1) It is proposed that physiologically meaningful measures of mass activities should have the character of time averages. The advantages of continuous integration are discussed. 2) For a comparison of the mass activities from different structures the method of the ongoing cross-correlation coefficient is proposed. The properties of the method are discussed and some preliminary results are reported showing its usefulness in the investigation of the so-called steady state activities.
