title: Potassium channels in mouse neonate dorsal root ganglion cells: a patch-clamp study.
abstract: Isolated neurons from mouse neonate dorsal root ganglia were analyzed using both whole-cell clamp and single-channel recording techniques and presented a complex repertoire of potassium (K) channels. Different types of potassium channels have been found: calcium-activated K channel presenting a large unit conductance of 260 pS in symmetrical K; voltage-dependent K channels of 130 pS without calcium-dependence; two types of inward rectifying K channels (90 and 120 pS in symmetrical K); low probability K channels; delayed rectifier channels and non-selective cationic channels.
