Hadron properties are modified when the hadron is embedded in a nuclear medium. Here we discuss the Gerasimov-Drell-Hearn, GDH, sum rule for polarised photoproduction from a polarised nucleon within a polarised nuclear target. Strong enhancement is expected with the suppression of the proton and nucleon resonance masses and enhancement of the proton’s anomalous magnetic moment in medium. This could be tested in polarised photoproduction experiments with interesting targets being polarised deuterons, ^3He, ^6Li and ^7Li. The largest contribution to the GDH sum rule comes from the Delta resonance excitation. In existing data with polarised deuterons and ^3He the Delta excitation is shifted to slightly lower energy when compared to model predictions where the Delta is treated with its free mass.
