Negative slope conductance at large depolarizations in cat spinal motoneurons.
The current-voltage relation of cat spinal motoneurons obtained by somatic voltage clamp exhibits a region of negative slope conductance at large depolarizations in addition to the previously reported N-shaped region at small depolarizations. The N shape at large depolarizations is caused by one outward current component which grows larger and then smaller with depolarization.
