摘要：

Rhythmic neuronal activity preceding C4 inspiratory activity (Pre-I neuron activity) was recorded in rostral ventrolateral (near ventral surface) medulla of brainstem-spinal cord preparation isolated from newborn rat. Vagal stimulation inhibited C4 activity but not Pre-I neuron activity. Rhythmic Pre-I neuron-like activity was still recorded in the block of rostral medulla after transection. Results suggest that Pre-I neurons generate the basic respiratory rhythm and trigger inspiratory activity.
