Endocannabinoid regulation of gastric vagal afferent signalling
Background: Gastric vagal afferents (GVAs) play a role in peripheral appetite control. Tension sensitive GVAs respond to stretch or distension of the stomach sending signals to the hindbrain to produce feelings of fullness and satiety. The sensitivity of tension sensitive GVAs is reduced in …

Neural substrates of avoidance behavior: The afferent limb
… active avoidance conditioning, sources of afferent input to critical learning-related limbic structures were examined for their influence on neuronal activity and behavior.

Naᵥ1.8+ Visceral Afferent Neurons: Roles in Metabolism and Inflammation
… of inflammatory signaling pathways. As vagal afferents are a neuronal population that can rapidly respond to both food-related stimuli as well as inflammatory agents and cytokines, I hypothesized that intact vagal afferent function may be required for proper regulation of energy balance and …

Transfer Properties of the Hair Cell-Afferent Fiber Synapse
… and postsynaptic elements of the hair cell's afferent synapse. The transfer properties of this ribbon-type synapse have been explored with a variety of electrophysiological techniques, including whole-cell recordings, capacitance measurements, and iontophoresis. Glutamate is released from hair …

Mechanisms of thermal sensitivity in rodent primary afferent neurons innervating the skin
… recordings carried out from rodent primary afferent neurons using the in vitro skin nerve preparation in an attempt to reveal mechanisms underlying thermal sensitivity. The discovery of thermally sensitive transient receptor potential (TRP) ion channels has given insights into the molecular …

Interaction Of Afferent Renal Nerve Activity And Il-1R Signaling In Hypertension
… are due to ablation of sympathoexcitatory afferent renal nerves, which are overactive under conditions of renal inflammation. Renal interleukin 1-beta (IL-1β) is elevated in many cases of hypertension, as well as the DOCA-salt model of hypertension, and its activity may be responsible for …

The role of renal afferent signalling in chronic intermittent hypoxia-induced sympathoexcitation and hypertension
… blood pressure through the disruption of renal afferent nerve signalling. Renal oxidative stress and inflammation are evident following exposure to chronic intermittent hypoxia (CIH) in addition to blunted baroreflex control of heart rate. However, little information is available about the …

System identification and modeling of primary electrosensory afferent response dynamics in the weakly electric fish Apteronotus leptorhynchus
… into trains of action potentials in primary afferent nerve fibers. Using amplitude modulations (AMs) of the electric organ discharge (EOD), we systematically studied the stimulus coding properties of probability coding (P-type) electrosensory afferents in the weakly electric fish Apteronotus …

THE EFFECTS OF GASTRIC AND HOMEOSTATIC AUTONOMIC AFFERENT REFLEXES ON CARDIAC AUTONOMIC EFFERENT ACTIVITY IN HEALTHY HUMAN VOLUNTEERS
The effects of gastric autonomic afferent reflexes on cardiovascular autonomic efferent activity are regarded as a direct neural effect of the activation of gastric receptors which send afferent inputs to the central nervous system (CNS) to cause various cardiovascular changes (Van Orshoven et al., …

Modulation of cochlear afferent response by the lateral olivocochlear system : activation via electrical stimulation of the inferior colliculus
… terminations on outer hair cells and cochlear afferent terminals, respectively. The cochlear effects of electrically activating MOC efferents are well known: the MOC efferents suppress cochlear responses by reducing outer hair cells' contribution to cochlear amplification. In contrast, LOC …

Smooth Muscle-Specific Removal of Brain-Derived Neurotrophic Factor Results in Increased Vagal Afferent Innervation to the Intestine and Increased Satiation in Mice
<p>Vagal afferents transmit signals regarding food-derived stimuli in the gastrointestinal (GI) tract to the brain. Vagal mechanoreceptors called intraganglionic laminar endings (IGLEs) innervate the smooth muscle wall of GI organs and detect stretch and tension to regulate GI reflexes and …

Synaptic Specificity in the Zebrafish Lateral Line
… known as neuromasts. Here I show that each afferent neuron of the posterior lateral line establishes specific contacts with hair cells of the same hair-bundle polarity. I quantify this specificity by modeling the neuron as a biased selector of hair-cell polarity and find evidence for bias …

Modulation of mechanosensitive gastro-oesophageal vagal afferents by novel targets.
Modulation of signals from peripheral vagal afferent mechanoreceptors to the central nervous system has been identified as the most accessible target for control of neuronal pathways and reflexes central to gastrointestinal disorders such as GORD, disordered food intake and functional dyspepsia. …
