Key features of antiferromagnetic dynamical correlations in high-TC superconductors cuprates are discussed. In underdoped regime, the sharp resonance peak, occuring exclusively in the SC state, is accompanied by a broader contribution located around ∼ 30 meV which remains above TC. Their interplay may induce incommensurate structure in the superconducting state.
