The Application of Phase Synchronization in Continuous Neural Signals

Synchronization is an important feature in the exchange of information and the establishment of interconnections between the different regions of the brain. Phase-based synchronization is a very effective method in the analysis of neural signal synchronization. In this paper, the method of phase-based synchronization was used to calculate the phase lock value (PLV) of the local field potential(LFP) signal between the prefrontal cortex (PFC)and striatum(STR) in the monkey. We found that the phase synchronism in the beta frequency band was clearly different for different test conditions and different test stages between the two brain regions of the monkey. The beta-band LFP signal was more synchronous. The beta-band LFP signal was important in the exchange of information between two different brain regions.
