[Ganglionic synapses and synaptic transmission after axotomy of sympathetic neurons in the frog].
In frog ganglia, efficacy of synaptic transmission was analyzed in parallel with the number of synapses at different times after axotomy of sympathetic neurons: the number of synapses was at their minimum at two weeks whereas depression of synaptic transmission was strongest at one month. The relationship between the presence of synaptic dense specializations and the existence of efficacious transmission is discussed.
