A study of the action of some drugs on frogs.

The discovery by Loewi (1921) that the slowing of the heart during vagal stimulation was due to the release at the nerve ending of a chemical substance, led to the study of transmission at other synapses. Although much success has been achieved at various periferal synapses, no chemical transmitter at the G.N.S. synapses has definitely been discovered or proven. The complexity of the G.N.S. is such that many supposedly similar experiments give conflicting results. One explanation for these conflicting results obtained when dealing with the G.N.S. would be that there is probably more than one synaptic transmitter, and that a substance may be excitatory at one synapse but inhibitory at another.
