Differences of information transmission network hub, network aggregation and minimum path of information transmission under the states of photon stimulation and resting are studied. The brain functional network is constructed based on the small-world network theory. By analyzing the network connectivity of brain function, cluster coefficient and the minimum path, the conclusion is drawn that stronger functional areas of information transferring are the insula and the posterior cingulate state. Thalamus and hippocampus have a greater aggregation. The information amount of photon stimulation from superior frontal gyrus to the middle occipital gyrus is passed through middle temporal gyrus under the photon stimulation. Those are drawn under rest state that stronger functional areas of information transferring are the cuneus and the lingual gyrus, the central lobule and superior temporal gyrus have a greater aggregation; the information amount of photon stimulation from left superior frontal gyrus to left the middle occipital gyrus is passed through middle temporal gyrus, cuneus and that from right superior frontal gyrus to right the middle occipital gyrus is passed through anterior cingulate gyrus and inferior occipital gyrus.
