 Neuronal Receptors (10)
  
SN Property present CF-Compartment Receptor Connect Note Publication facts
1 Yes Distal equivalent dendrite AMPA Morphological evidence of local contact by pyramidal neurons
2 Yes Axon terminal Cholinergic Receptors Ach action: pre- or postsynaptic? Cholinergic agonist carbachol caused a significant suppression of inhibitory postsynaptic potentials (IPSPs) in the pyramidal neurons that were induced by stimulation of layer Ib, with a weaker effect on IPSPs induced by stimulation of layer Ia
3 Yes Soma Cholinergic Receptors Acetylcholine action: pre- or post-synaptic? Cholinergic agonist carbachol caused a significant suppression of inhibitory postsynaptic potentials (IPSPs) in the pyramidal neurons that were induced by stimulation of layer Ib, with a weaker effect on IPSPs induced by stimulation of layer Ia
4 Yes Distal equivalent dendrite 5-HT2 PKC may have a negative feedback role in modulating excitation by 5-HT in piriform cortical interneurons
5 Yes Distal equivalent dendrite Alpha1 A subpopulation of interneurons in layer III of the rat piriform cortex are excited by 5-hydroxytryptamine (5-HT) via 5-HT2A receptors and by norepinephrine via alpha 1-adrenoceptors.
6 Yes Distal equivalent dendrite Monoamine Receptors IPSPs elicited by monoamines in pyramidal cells result from a convergence of inputs from populations of layer II/III interneurons that are activated by one, two or all three of the following monoamines 5-HT, NE, and DA.
7 Yes Soma Gaba GABAergic input? GABAergic interneurons in deeper layers of piriform cortex receive symmetric synapses as well as asymmetric synapses
8 Yes Proximal equivalent dendrite Gaba GABAergic input? GABAergic interneurons in deeper layers of piriform cortex receive symmetric synapses as well as asymmetric synapses
9 Yes Axon terminal GabaB GABAB presynaptic mechanism? Although both the soma and distal dendrites have both the fast and slow GABAA-mediated IPSCs, there is a greater proportion of slow component in the dendrites. Slow GABAA mediated IPSC component is regulated by presynaptic GABAB inhibition (at the interneuron terminals?) whereas the fast is not
10 Yes Distal equivalent dendrite NMDA
 Neuronal Currents (4)
  
SN Property present CF-Compartment Current Connect Note Publication facts
1 Yes Soma I T low threshold
2 Yes Soma I Na,t TTX-sensitive sodium current (possibly of the transient type?) may also be present
3 Yes Soma I M I M may contribute to a sag and rebound of voltage response to hyperpolarizing current steps
4 Yes Soma I A Some diferences in the neurons in the deeper layers (v.s. those in the superficial layers) can be accounted for by differences in the IA channel in the cells
 Neuronal Transmitters (1)
  
SN Property present CF-Compartment transmitter Connect Note Publication facts
1 Yes Axon terminal Gaba onto pyramidal neuron Dendritic GABAA-mediated IPSPs act largely independent of somatic IPSPs and may regulate facilitation of MNDA-mediated respnses
