Brain　functional　network　studies　have　demonstrated　the　small-world　topology　as　the　nature　of　large-scale　spontaneous　brain　activity.　Studies　have　also　revealed　that　the　temporal　coherence　of　spontaneous　activity　could　be　reshaped　during　task-dependent　(or　post-task)　resting　states　within　local　spatial　patterns　such　as　task-related　and　the　default-mode　networks.　However,　to　our　best　knowledge,　it　is　still　a　lack　of　rigorous　investigations　that　whether　the　small-world　topology　of　spontaneous　intrinsic　organization　remains　robust　and　stable　during　different　resting　states.　To　address　the　problem,　we　recorded　blood　oxygen　level-dependent　(BOLD)　signals　from　two　rests　(namely,　pre-　and　post-task　resting　states)　before　and　after　a　simple　semantic-matching　task,　and　investigated　the　preceding　task　influences　on　the　topology　of　the　large-scale　spontaneous　intrinsic　organization　during　the　post-task　resting　state.　The　major　findings　are　that　the　small-world　configuration　of　spontaneous　intrinsic　organization　remains　robust　and　stable　during　resting　states　regardless　of　preceding　task　influences.　©　2011　Springer-Verlag.
