A study using simultaneous intracellular recording from interneurons and pyramidal neurons combined with biocytin cell fills and morphological reconstructions revealed that the interneurons made connections onto the soma and proximal dendrites of the pyramidal neuron and that stimulation of the interneurons evoked IPSPs in the pyramidal neurons. EM microscopy revealed differential numbers of terminals depending on the subcellular locus of the connections. |

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. |

A-channel regulate timing of dendrodendritic inhibition between Mitral cells and granule cells |
129 |
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. |

Ach exerted two distinct effects on fast-spiking interneurons: Ach directly depolarized FS interneurons by acting on nondesensitizing soma-dendritic nicotinic receptors. In addition, Ach attenuated the GABAergic inhibition of projection neurons by fast-spiking interneurons through activation of presynaptic muscarinic receptors |

Activation of mGluR increases GC excitability, an effect that should increase GC-mediated GABAergic inhibition of mitral cells |
141 |
Activation of mGluR1 in Purkinje cells causes a Ca-dependent release of a retrograde messenger, probably Glutamate, which acts on presynaptic ionotropic glutamatergic receptor (AMPA/kinate) on the parallel fibers (PFs), depolarizes PFs and modulates neurotransmission from parellel fibers to Purkinje cells |

Activation of muscarinic receptors decreases granule cell firing frequency, as well as modulates GABAergic synaptic inputs onto mitral cells. |

Activation of the adenosine A1 receptor reduces synaptic strength by modulating presynaptic calcium channels. Baclofen modulates presynaptic calcium channels as well but also affects release processes downstream from calcium entry |

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 |

Amplitudes of excitatory postsynaptic conductances (EPSCs) evoked in RTN neurons by minimal stimulation of corticothalamic fibers were 2.4 times larger than in relay neurons, and quantal size of RTN EPSCs was 2.6 times greater.

Amputation of the apical dendrite approximately 30 micron from the soma, while simultaneously recording the slow AHP whole cell current at the soma, depressed the sAHP amplitude by only approximately 30% compared with control. Somatic cell-attached and nucleated patches did not contain sAHP current. Amputation of the axon about 20um from the soma had little effect on the amplitude of the sAHP. By this process of elimination, it is suggested that sAHP channels may be concentrated in the basal dendrites of CA1 pyramids |
