This exploratory study is done to expand the possibility that vertebrates other than mammals possess similar primitive brain functions that has withstood the rigors of evolution. Resting-state modality which is commonly used to explore such a possibility in mammals is employed on the crucian carp, cyprinus carpio L. Long-range networks which are key to resting-state networks has been discovered and with very close anatomical specificity to previous axonal projection studies. This provides us motivation to believe that resting-state network is a basic global brain phenomenon in vertebrates.
