Extensive ARPES and low-energy inelastic neutron scattering studies of cuprate superconductors can be successfully described using a weak-coupling theory in which quasiparticles on a square lattice interact via scalar and spin-dependent effective interactions. In this article we point out that in Bi2Sr2Ca1−xYxCu2O8 (Bi2212) both probes are consistent with dominant near-neighbour Heisenberg interactions. We discuss the implications of this finding for the mechanism of high-Tc superconductivity.
