Abstract
The responses of normal and axotomized cells of frog sympathetic ganglia have been studied. Transmission through the ganglion gradually fails after axon section. The synaptic potential decreases progressively beginning about 3 days after axon section. The resting potential also falls and cell resistance decreases. Antidromic as well as directly evoked spike potentials become abnormally slow and small.
