In the frog, antidromic electrical stimulation of the ophthalmic branch of the trigeminal nerve (NV-ob) evokes a slow potential in the olfactory mucosa, modifies the activity of receptor cells and modulates the responses to odour. Substance P (SP) application evokes similar electrical responses. These results imply that the functioning of the olfactory system might be controlled at the receptor cell level. It is suggested that the trigeminal system could modulate the activity of the olfactory receptor cells via a local axon reflex which may result in the release of SP.
在青蛙中，对三叉神经眼支（NV-ob）进行逆向电刺激会在嗅觉黏膜中诱发一个缓慢电位，改变受体细胞的活性并调节对气味的反应。应用P物质（SP）会诱发类似的电反应。这些结果表明，嗅觉系统的功能可能在受体细胞水平受到控制。有人提出，三叉神经系统可能通过局部轴突反射调节嗅觉受体细胞的活性，这可能导致SP的释放。
