These results suggest that serotonergic afferents from raphe dynamically modulate olfactory processing through distinct effects on multiple OB targets, and may alter the degree to which OB output is shaped by inhibition during behavior. |

This channel is present in high density in all species. Original intracellular recordings suggesting site of impulse initiation is the axon hillock with backspread into the soma dendrites |

This current "may be of limited significance within the normal physiological range of potential and extracellular environment" |

This current is inactivated at rest and de-inactivated by hyperpolarization; sequences of hyperpolarization-depolarization therefore activate I A, producing the pauser reponse |

This is the non-selective Na and K current located in the plasma membrane of the distal segment. It is activated in the dark by cyclic GMP from the disc membranes. |

This persistant conductance may be activated by the NMDA receptor depolarization, providing a mechanism for graded, voltage dependent EPSP amplification |

Three types of glutamate receptors for 1) cone-activated receptors of HCs; 2) cone-activated receptors of OFF-BPs; and 3) rod-activated receptors found in HCs and BPs |

Thus there is a steady-state calcium current contributing to the depolarization phase of the oscillation but small in comparison with the sodium current." |

Tonically active at rest; induces a sag in hyperpolarizing responses; blocked by ACh. |

TTX-sensitive sodium current (possibly of the transient type?) may also be present |

Two types of A-like current were observed in GP neurons: a high-threshold, TEA-sensitive current attributable to Kv3.4 channels and a low-threshold, TEA-insensitive current attributable to Kv4 family channels.” |

Two types of PG cells can be distinguished by the presence of delayed-rectifier. R-type has DR current and shows outward rectification under current-clamp; N-type does not. A third type, X-type, has properties of both R- and N-type. Zinc modifies the A-type current, but not the delayed-rectifier type: at given voltages, it reduces A-current peak amplitude, slows its kinetics. Zinc shifts activation and inactivation toward more positive voltage. Thus, at physiological resting potential -55mV, zinc accelerates repolarization. |

Unpublished data by Chen and Shepherd have revealed a long lasting after hyperpolarization following a train of action potentials. Using whole-cell recordings, the kinetic properties of this current have been investigated in neurones from neonatal rats, which were retrogradely labelled and identified after enzymatic dissociation |

Using differential polarization through applied electric fields, cell bodies and dendrites have been activated in effective isolation during intracellular recordings in vitro. In neurons located in the rostral substantia nigra, the dendrites are shown to have both HVA and LVA channels. HVA conductance appears to be exclusively dendritic. By contrast, in more caudally located cells HVA calcium spikes were located principally in the cell body |
