5">Activation of NMDAR reduces transmission more in VH than in DH.
Activation of NMDAR enhances excitability and reduces inhibition in DH but not VH.
5">The mGluR5 potentiates the synergistic effects of NMDAR in DH but not VH slices.
The A2AR exerts permissive role on mGluR5–NMDAR synergy in DH only.
5">CB1R participates in mediating the synergistic effects of mGluR5–NMDAR.
