    The thesis demonstrates in a biological model the variation of the transfer velocity within the synfire concept. This phenomenon, is used for synchronization of the activities of two coupled synfire chains. The presented mechanism gives a tentative explanation for the way of applying correlated neuronal activities for information processing. The plausibility of representation and processing of neuronal information by means of correlation action potentials is tested by applying it to visual pattern recognition. The individual sequence of action potentials is determined by neighbouring interaction between the components of the pattern. By synchronization of synfire chains this signal sequence is compared with the sequence of action potentials which are formed by interaction of neighbouring image points in the picture. Optimum resonance between two local and temporal successions of action potentials proves a resemblance between the corresponding patterns. Continuous feed-back between interactions in the system contribute to recognition and segmentation of the pattern.
