Olfactory bulb main mitral cellProximal basal dendriteAMPA.(Petralia RS and Wenthold RJ, 1992 [rat ]15 ). With a postembedding immunogold procedure, it has been found that these receptors do not appear to be concentrated in clusters on dendrites, suggesting that the presynaptic effects of glutamate are mediated by a small complement of extrasynaptic receptors (Sassoe-Pognetto M and Ottersen OP, 2000264 ). The pharmacology and kinetics of glutamate sensitivity of mitral cells was studied using flash photolysis in rats (Lowe G, 2003464 ).
Olfactory bulb main mitral cellProximal apical dendriteNMDA.Auto-activation from glutamate released by mitral cell secondary dendrites (van den Pol AN, 1995 [rat ]1 ). Paired recordings in slices showed excitatory transmission mediated solely by transmitter spillover between mitral cells. Dendritic glutamate release causes self-excitation via local activation of NMDA receptors, and generates NMDA receptor-mediated responses in neighbouring cells. It is suggested that this simultaneous activation of neighbouring cells by a diffuse action of glutamate provides a mechanism for synchronizing olfactory principal cells (Isaacson JS, 1999234 ). The pharmacology and kinetics of glutamate sensitivity of mitral cells was studied using flash photolysis in rats (Lowe G, 2003464 ).
Olfactory bulb main mitral cellSomaNMDA.Paired recordings in slices showed excitatory transmission mediated solely by transmitter spillover between mitral cells. Dendritic glutamate release causes self-excitation via local activation of NMDA receptors, and generates NMDA receptor-mediated responses in neighbouring cells. It is suggested that this simultaneous activation of neighbouring cells by a diffuse action of glutamate provides a mechanism for synchronizing olfactory principal cells (Isaacson JS, 1999234 ). In an immunocytochemical study in zebrafish all cells resulted in NMDA receptor mediated labelling (Edwards JG and Michel WC, 2003460 ). The pharmacology and kinetics of glutamate sensitivity of mitral cells was studied using flash photolysis in rats (Lowe G, 2003464 ).
