A Reversible Low Frequency Alternating Current Nerve Conduction Block Applied to Mammalian Autonomic Nerves

Sensors, 2021
Electrical stimulation can be used to modulate activity within the nervous system in one of two modes: (1) Activation, where activity is added to the neural signalling pathways, or (2) Block, where activity in the nerve is reduced or eliminated.

Closed-loop bioelectronic block of stellate ganglia reduces neurotransmitter release and improves recovery following programmed ventricular pacing [PDF]

Frontiers in Bioengineering and Biotechnology
IntroductionThe autonomic nervous system governs cardiac function through a finely-balanced interplay of sympathetic and parasympathetic activity. Following myocardial infarction chronic sympathetic hyperactivation destabilizes this balance, increases ...

Kilohertz waveforms optimized to produce closed-state Na+ channel inactivation eliminate onset response in nerve conduction block.

PLoS Computational Biology, 2020
The delivery of kilohertz frequency alternating current (KHFAC) generates rapid, controlled, and reversible conduction block in motor, sensory, and autonomic nerves, but causes transient activation of action potentials at the onset of the blocking ...

Stimulation parameters for directional vagus nerve stimulation

Bioelectronic Medicine, 2023
Background Autonomic nerve stimulation is used as a treatment for a growing number of diseases. We have previously demonstrated that application of efferent vagus nerve stimulation (eVNS) has promising glucose lowering effects in a rat model of type 2 ...
