The authors show that activation of GluK2-containing kainate receptors on hippocampal neurons, by either agonist application or high-frequency synaptic stimulation, leads to a new form of NMDA-receptor-independent LTP. Induction of this form of plasticity requires the metabotropic action of postsynaptic kainate receptors, which triggers spine growth and potentiation of AMPA-receptor-mediated transmission.
