Electrical properties and morphology of 21 genioglossal motoneurons were measured in a slice preparation of the rat brainstem at four different postnatal ages. The motoneurons labeled with neurobiotin were reconstructed and quantified in three-dimensional space. There was no strong correlation found between the input resistance or membrane time constant and the total membrane surface area. We conclude that there is no electrical property of these developing motoneurons that can accurately predict their anatomical size.
在四个不同的出生后年龄阶段，对大鼠脑干切片制备中的21个颏舌肌运动神经元的电特性和形态进行了测量。用神经生物素标记的运动神经元在三维空间中进行重建和量化。未发现输入电阻或膜时间常数与总膜表面积之间存在强相关性。我们得出结论，这些发育中的运动神经元的电特性无法准确预测其解剖学大小。
