Langleys Nicotine Test




The test is the following: First stimulate the Preganglionic Fiber and notice the response that appears. By adding a large dose of Nicotine , the Ganglion (site of relay beteween pre- and postganglionic fibers) is blocked. Now the preganglionic Fiber is restimulated again.

If there is still a response, the Fiber does not relay in the Ganglion . But if there is no response, the Fiber relays ("synapses") in the Ganglion .
