Capsaicin-sensitive afferent fibers
of the common hepatic branch of the vagus project towards the rat liver (34).
It is physiologically controlled by excitatory presynaptic potentials of Ia afferent fibers
and inhibitory postsynaptic potentials from muscle spindles of antagonistic muscles.
A recent dosimetric study  revealed that a typical cochlear implant delivered, at the location of the afferent fibers
of the auditory nerve, a peak voltage of several tens of mVs, higher than the signal amplitudes used in this work ([less than or equal to] 10 mV).
For MI + SS and SS alone, this decrease may be due to the stimulation frequency, inducing homosynaptic post activation depression (HPAD) related to the repetitive stimulation of afferent fibers
. However, after MI alone, this decrease may be related to a stimulation effect at Per and/or a condition effect.
An electrode cuff is placed around the right (or left cervical vague) aiming to stimulate both the vagal efferent and afferent fibers
The possible underlying mechanism of extraordinary symptoms during supraventricular tachycardia has been supposed to be cross-talk between the cardiac afferent fibers
and cranial nerves or ganglia through the impulse propagation .
Nociceptive inflow from these suboccipital structures is mediated by smalldiameter afferent fibers
in the upper cervical roots terminating from the C2 segment up to the medullary dorsal horn [9,14,15].
Furthermore, Spinal Manipulation (SM) could have had a twofold effect, acting on (i) the skeletal muscle hypertonia, via the efferent projection from the CNS; (ii) the enteric, sympathetic, and parasympathetic systems, via the afferent fibers
located in dorsal root or cranial nerve ganglia .
Primary afferent nerve fibers include extrinsic and intrinsic afferent fibers
that govern the GI tract.
Most, if not all, studies have restricted their work on brain, at a large macroscopic level, without particular focus on a more cellular localization such as neurons, glial cells and/or vascular tissue (capillary) and neurotoxin for small-diameter primary afferent fibers
(C and A delta).
Prior scientific evidence shows that when the active device stimulates the afferent fibers
of the vagus nerve, there is a rapid and sustained change in brain chemistry characterized by the release of inhibitory neurotransmitters, and a decrease in the over-expression of the excitatory neurotransmitter glutamate.
