[Passive cable properties of relay cells in dorsal lateral geniculate nucleus of the rabbit].
We measured the passive membrane properties of 24 relay cells in slice preparation of the lateral geniculate nucleus of the rabbit. The resting membrane potential was -62.7 +/- 4.1 mV (mean +/- SD) with an input resistance of 30.4 +/- 11.2 M omega. According to Rall's linear cable model, the electrotonic length (L) of the dendrite was 0.79 +/- 0.13. The voltage attenuation factor (H) was 1.33 +/- 0.11. All these indicated that the relay cells were electrically compact. DC voltage on the distal dendrite could spread to the soma attenuated only by 25%.
