In order to analyze the mechanism of phase in information processing related to working memory task, the discrepancy of phase synchronization of local field potentials in ventral hippocampus and medial prefrontal cortex between rest state and working memory encoding were compared and studied. The research data were the local field potentials of ventral hippocampus and medial prefrontal cortex obtained during rest state and Y-maze spatial working memory task of 6 SD rats. The weighted phase lag index between the local field potentials of the two brain regions was calculated. The results show that the phase synchronization in working memory encoding between ventral hippocampus and medial prefrontal cortex selectively and significantly increases in theta band compared with rest state. The phase synchronization of theta band between ventral hippocampus and medial prefrontal cortex is a mechanism of task related information processing in working memory encoding.
