MPI-based method and system for extracting brain function activation area of primate face cognition

Abstract

The present application belongs to the field of MPI imaging and brain function region extraction, and particularly relates to a method and system for extracting primate face cognition brain function activation region based on MPI, comprising: collecting primate brain data under visual task stimulation through an MPI system, performing image reconstruction to obtain time sequence images corresponding to the visual task; combining primate brain anatomical images to perform region positioning and division, obtaining m signal nodes of the temporal lobe region of the brain and m signal nodes of the frontal lobe region of the brain; respectively performing signal time sequence extraction and correlation coefficient calculation to obtain m correlation coefficients α of the temporal lobe region of the brain and m correlation coefficients β of the frontal lobe region of the brain; respectively performing t test on the m correlation coefficients α and the m correlation coefficients β, and if the p value is less than a set t test threshold, obtaining the primate face cognition brain function activation region corresponding to the visual task stimulation. The present application realizes accurate and high-precision extraction of the primate face cognition brain function activation region without radioactivity.
