1 Yes Distal equivalent dendrite mGluR5 Activation of mGluR5 increases GC excitability, an effect that should increase GC-mediated GABAergic inhibition of mitral cells
2 Yes Distal equivalent dendrite NMDA NMDA receptor is required for DDI (dendrodendritic inhibition) since IPSC was completely blocked by AP-5. Ineffectiveness of AMPA receptor-mediated EPSPs to activate the granule cells may be due to their intrinsic membrane properties.
3 Yes Distal equivalent dendrite AMPA DDI (dendrodendritic inhibition) can be elicited by activation of AMPA receptors, while NMDA receptor activation is not an absolute requirement. DDI is blocked by Cd and toxins to N- and P/Q-type channels.
4 Yes Soma GabaA Cell-specifc modulation of GABAA receptor- mediated chloride current by dopamine. In interneurons (mainly granule cells), dopamine reduces GABAA Cl- current, via D1 receptor and involves phosphorylation of GABAA receptors by PKA. In mitral cell, dopamine enhances GABA responses via activation of D2 receptors and phosphorylation of GABAA receptors via PKC.
5 Yes Soma Dopaminergic Receptor primary culture Cell-specifc modulation of GABAA receptor- mediated chloride current by dopamine. In interneurons (mainly granule cells), dopamine reduces GABAA Cl- current, via D1 receptor and involves phosphorylation of GABAA receptors by PKA. In mitral cell, dopamine enhances GABA responses via activation of D2 receptors and phosphorylation of GABAA receptors via PKC.

SN Property present CF-Compartment Current Connect Note Publication facts
1 Yes Distal equivalent dendrite I A A-channel regulates timing of dendrodendritic inhibition between mitral and granule cells: The transient IA attenuates dendrodendritic input mediated by fast-acting AMPA receptors, such that the excitation and subsequent inhibitory output of granule cells follows the prolonged kinetics of their NMDA receptors. Altering weights of AMPA and NMDA inputs by modulating IA provides a mechanism to regulate the timing of inhibition. A-channels are localized in dendrites.
