Skin sympathetic nerve activity in humans during exposure to emotionally-charged images: sex differences

Frontiers in Physiology, 2014
While it is known that anxiety or emotional arousal affects skin sympathetic nerve activity (SSNA), the galvanic skin response (GSR) is the most widely used parameter to infer increases in SSNA during stress or emotional studies.

The contribution of peripheral nerves to the pleasure from scratching an itch: Evidence from a neuronopathy participant

The Journal of Physiology, EarlyView.
Abstract figure legend Acute itch was experimentally induced using histamine and cowage in control participants (with no neuronopathy) and in IW, a participant with a large‐fibre sensory neuronopathy resulting in the loss of Aβ afferent function below C3, at the same time as largely preserving Aδ and C‐fibre function.

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

A purposely designed neural signal amplifier for short interval stimulation and recording microneurography using a common electrode

, 2006
'Common Electrode' microneurography (i.e. stimulating a nerve and recording return afferent neural activity through the same microelectrode facilitates investigation of linkages between sensory and motor nervous systems in humans.

Single human fingertip mechanoreceptive afferents simultaneously encode multidimensional aspects of touch

The Journal of Physiology, EarlyView.
Abstract figure legend Mechanoreceptors in the fingertip skin allow us to explore objects and to feel a vast range of textures. We recorded responses from individual low‐threshold mechanoreceptive afferents in humans while dynamic stimuli were swept across their receptive fields, systematically varying force, velocity and spatial period.

Sympathetic responses to central hypovolemia: New insights from microneurographic recordings

Frontiers in Physiology, 2012
Hemorrhage remains a major cause of mortality following traumatic injury in both military and civilian settings. Lower body negative pressure (LBNP) has been used as an experimental model to study the compensatory phase of hemorrhage in conscious humans,
