The role of kainate receptors in producing synaptic plasticity is …
Web4 de nov. de 2011 · Synaptic plasticity has been studied in all three hippocampal pathways. Distinct stimuli elicit changes in synaptic efficacy; high-frequency stimuli produce synaptic strengthening called long-term potentiation (LTP), and low-frequency stimulation produces synaptic weakening, called long-term depression (LTD).
