Contribution of sympathetic nervous system activation to endothelial ischemia reperfusion injury in healthy adults

Physiological Reports
Ischemia–reperfusion injury (IRI) describes the phenomenon through which the restoration of blood flow following prolonged ischemia exacerbates tissue damage during reperfusion.

Inter-individual Relationships between Sympathetic Arterial Baroreflex Function and Cerebral Perfusion Control in Healthy Males

Frontiers in Neuroscience, 2017
Maintenance of adequate cerebral perfusion during normal physiological challenges requires integration between cerebral blood flow (CBF) and systemic blood pressure control mechanisms. Previous studies have shown that cardiac baroreflex sensitivity (BRS)

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...

Vibrotactile intensity perception: Predominant influence of afferents recruited remote from stimulus site

The Journal of Physiology, EarlyView.
Abstract figure legend We delivered trains of brief mechanical pulses to the fingertips of subjects to investigate vibrotactile intensity perception. Some stimuli consisted of bursts of up to four pulses. Simulated responses of the tactile afferent population across the hand revealed that afferents innervating the skin directly under the probe reliably

Marked C‐tactile afferent suppression by a plastic film does not proportionately diminish pleasantness of gentle brushing

The Journal of Physiology, EarlyView.
Abstract figure legend Human skin contains several classes of mechanoreceptive afferents that encode mechanical stimulation. For example, C‑tactile (CT) afferents are suggested to signal the pleasant aspects of gentle touch and are activated effectively by slow brushing of hairy skin.

A Comparison of Muscle Sympathetic Nerve Activity to Non-contracting Muscle During Isometric Exercise in the Upper and Lower Limbs

Frontiers in Neuroscience, 2019
Previous research indicates that greater sympathetic vasoconstrictor drive to skeletal muscle occurs during isometric upper limb exercise compared to lower limb exercise.

Dynamic memory in rodent C‐fibres and its impact on spinal nociceptive processing

The Journal of Physiology, EarlyView.
Abstract figure legend Nociceptive C‐fibres display activity‐dependent slowing (ADS) whereby successive action potentials are conducted progressively slower thus regulating the temporal relay of pain signals. This study shows that the ADS induced by short stimulus trains (which mimic stimulus evoked firing, shown in orange) is modified by prior ...

Microneurography: Recordings from single neurons in human peripheral nerves

Over the last 50 years, the technique of microneurography has provided us with valuable insights into activity in human nerves. Microneurography allows us to record from the axons of single neurons in various peripheral nerves across the body.
