- AMPA Receptors (75)
- Delta Receptors (2)
- Kainate Receptors (25)
- NMDA Receptors (77)
- Metabotropic Glutamate Receptors (39)
The excitatory effects of glutamate (the major excitatory neurotransmitter) are mediated by the activation of ionotropic and metabotropic receptors. These receptors differ in their molecular, biochemical, physiological and pharmacological properties.
The ionotropic glutamate receptors are divided into three main categories: AMPA, NMDA (N-methyl-D-aspartate) and Kainate receptors.
