Comparison of the electrical properties of ventrally and dorsally derived mature OLs (vOLs and dOLs) in the forebrain. A, A vOL expressing tdTom in Gsh2-Cre: Sox10-GFP/tdTom mice (left) was whole-cell clamped with an internal solution containing Lucifer yellow (green: middle); thin green processes are internodes. Right panel shows overlay. Current traces are in response to 20 mV steps from −70 mV. B, As in A but for a dOL expressing eGFP in Gsh2-Cre: Sox10-GFP/tdTom mice; thin red processes are internodes. C, Comparison for vOLs (tdTom) and dOLs (eGFP) of membrane resistance at −70 mV. D, Percentage of vOLs (tdTom) and dOLs (eGFP) with different numbers of internodal processes (10 vOLs and 11 dOLs were studied). E, Mean number of internodal processes made by vOLs and dOLs. F, Specimen responses of an OL to kainate (100 μm) and NMDA (60 μm) at −70 mV. G, Magnitude of drug-evoked currents (as in F) for vOLs and dOLs.
