The distribution of Gp1 mGluRs at glutamatergic synapse. Gp1 mGluRs are mostly localized postsynaptically and promote a calcium influx upon their activation and contribute to LTP/LTD induction. mGluR5 also modulates synaptic release probability by depleting PIP2. The astrocytes also express mGluR5.
