Customer experience as a boardroom topic is more relevant than ever. Enterprises are investing significant digital transformation budgets and commissioning large projects to elevate CX. Yet more than 70 percent of digital transformation projects fail to move the needle at scale. One topic that has a substantial impact on CX is the transformation of customer service operations using digital tools.

The action potential (AP) waveform controls the opening of voltage-gated calcium channels and contributes to the driving force for calcium ion flux that triggers neurotransmission at presynaptic nerve terminals. Although the frog neuromuscular junction (NMJ) has long been a model synapse for the study of neurotransmission, its presynaptic AP waveform has never been directly studied, and thus the AP waveform shape and propagation through this long presynaptic nerve terminal are unknown. Using a fast voltage-sensitive dye, we have imaged the AP waveform from the presynaptic terminal of male and female frog NMJs and shown that the AP is very brief in duration and actively propagated along the entire length of the terminal. Furthermore, based on measured AP waveforms at different regions along the length of the nerve terminal, we show that the terminal is divided into three distinct electrical regions: A beginning region immediately after the last node of Ranvier where the AP is broadest, a middle region with a relatively consistent AP duration, and an end region near the tip of nerve terminal branches where the AP is briefer. We hypothesize that these measured changes in the AP waveform along the length of the motor nerve terminal may explain the proximal-distal gradient in transmitter release previously reported at the frog NMJ.

SIGNIFICANCE STATEMENT The AP waveform plays an essential role in determining the behavior of neurotransmission at the presynaptic terminal. Although the frog NMJ is a model synapse for the study of synaptic transmission, there are many unknowns centered around the shape and propagation of its presynaptic AP waveform. Here, we demonstrate that the presynaptic terminal of the frog NMJ has a very brief AP waveform and that the motor nerve terminal contains three distinct electrical regions. We propose that the changes in the AP waveform as it propagates along the terminal can explain the proximal-distal gradient in transmitter release seen in electrophysiological studies.

Although amphibians are known Salmonella carriers, aquatic African dwarf frogs are specifically marketed toward children, who are especially vulnerable to Salmonella infections. Both direct animal contact and indirect contact with animal habitats can lead to human Salmonella infections.

This is the first reported outbreak of human Salmonella infections associated with African dwarf frogs, particularly among young children. Parents should be aware of the risk of Salmonella infections from both direct and indirect animal contact. Pediatricians should regularly inquire about animal contact and advise families about risks.
