In　this　paper,　the　synchronization　problem　of　coupled　reaction-diffusion　neural　networks　(CRDNNs)　is　considered　by　using　pinning　event　-triggered　sampled　-data　(PETSD)　control　method　under　spatially　point　measurements.　To　save　the　limited　transmission　channel,　a　PETSD　control　mechanism　by　controlling　a　small　fraction　of　the　nodes　is　proposed　to　decrease　the　update　frequency　of　controller　and　the　unnecessary　SD.　Then,　based　on　the　Lyapunov-Krasovskii　functional　(LKF)　and　inequality　techniques,　sufficient　conditions　for　exponential　stability　of　the　synchronization　error　system　presented　by　linear　matrix　inequalities　(LMIs)　can　be　derived　through　the　designed　PETSD　controller.　Finally,　simulation　results　of　one　numerical　example　are　presented　to　demonstrate　the　effectiveness　of　the　proposed　design　approach.
