showed that the proximal dendrites and somata of hippocampal neurons label for L-type Ca2+ channels and that these channels tend to cluster near the bases of the neural processes. In patch recordings, "HVA-l channels reminiscent of L-type channels were occasionally encountered primarily in the more proximal dendrites" (and in the soma) |

Simultaneous recordings were carried out in visual cortical slices. Assuming open probability of non-NMDA receptor channels to be 0.7, it is suggested that the number of channels available for synaptic transmission between individual pyramidal cells would be 74 (kittens) and 59 (rats) |

Simultaneous whole-cell recordings, made from the soma and dendrites rat brain slices, showed that AP evoked by either current pulses or synaptic stimulation of parallel or climbing fibers, always occurred first at the soma and decreased in amplitude with increasing distance into the dendrites. Simultaneous somatic and axonal recordings showed that these action potentials were initiated in the axon |

Simultaneous whole-cell recordings, made from the soma and dendrites rat brain slices, showed that AP evoked by either current pulses or synaptic stimulation of parallel or climbing fibers, always occurred first at the soma and decreased in amplitude with increasing distance into the dendrites. Simultaneous somatic and axonal recordings showed that these action potentials were initiated in the axon. Outside-out patches excised from the soma and dendrites up to about 100um revealed a channel density decreasing with distance from the soma. |

Single action potential backpropagations show dichotomy of either strong attenuation (26-42%) or weak attenuation (71-87%). The dichotomy seems to be conferred primarily by differences in distribution, density, etc. of voltage dependent sodium and potassium channel (A-type, especially ) along the somatodendritic axis |

Single-cell-reverse transcription-polymerase chain reaction analysis of glycine receptor-subunit expression was combined with whole-cell recordings from acutely isolated cholinergic interneurons. Subunits alpha2, beta, alpha3, were found to be associated with receptor properties such as efficacy and desensiutization. Celllular localization of receptors unclear, but presumably on soma (?) |
