Layer Ia horizontal cells receive a very small number of symmetrical synapses (presumably GABAergic?), in contrast to interneurons of the deeper layers of the piriform cortex -- globular, multipolar cells |

Layer-4 basket cell axons make lateral connection isotropically near cell body ( 50 microm radius), but beyond this core region, anisotropically, preferably within a particular angular sectors cell body |

Leads to a fast EPSP which allows an influx of cations. This can work with the M1 receptors to switch the cell from burst to tonic mode |

Low-voltage-activated (LVA) and high-voltage-activated (HVA) Ca2+ currents were observed in the isolated rod bipolar cell terminal recordings |

Macropatch clamp and intracellular recordings in guinea pigs suggested that the pattern of Ca2+ spike firing in the dendrites of Purkinje cells is dynamically modulated by a highly aminopyridine-sensitive K+ current, and probably also by a Ca2+-activated potassium current |

May generate long delays contributing to temporal patterns (Ketchum and Haberly 1991); may play a role in epileptogenesis |

Mechanisms underlying suppression of this current by odorants were investigated in newt ORNs using the whole-cell version of the patch-clamp technique |

Membrane patches recorded in the cell-attached patch configuration from the soma and apical dendrites revealed an Ih that increased over sixfold from soma to distal dendrites. Ih demonstrated a mixed Na+-K+ conductance and was sensitive to low concentrations of external CsCl. As a result of Ih the propagation of subthreshold voltage transients is directionally specific.The elevated dendritic Ih density decreases EPSP amplitude and duration and reduces the time window over which temporal summation takes place |

Mitral-cell soma-dendrites act as a presynaptic terminal to the granule cell; the circuit is recurrent onto the injected cell; and the inhibitory transmitter is GABA |

mRNA of A-channel subunit Kv4.2 is expressed predominantly in granule cells. (In contrast, that of Kv4.3, also of A-channel, is expressed predominantly in periglomerular cells) |

Neostriatal cholinergic interneurons fire irregularly but tonically in vivo. The summation of relatively few depolarizing potentials and their temporal sequence are thought to underlie spike triggering and the irregularity of action potential timing, respectively |

Nitric oxide, released from both mitral and granule cells, is involved in olfactory memories and may act as a retrograde and/or intracellular messenger. However, only mitral cells expressed guanylyl cyclase subunits. |

NMDA and AMPA conductances properties were studied using patch-clamp recordings in morphologically identified cells in slices prepared from surgically removed medial temporal lobe specimens of epileptic patients (14 specimens from 14 patients). The wide range of changes in the slope conductance of the NMDA EPSCs suggests that the NMDA-receptor-mediated conductance could be altered in human epileptic DGCs |
