Journal ArticleDOI
Autonomic markers of emotional processing: skin sympathetic nerve activity in humans during exposure to emotionally charged images.
Rachael Brown,Rachael Brown,Cheree James,Luke A. Henderson,Vaughan G. Macefield,Vaughan G. Macefield +5 more
TL;DR: It is concluded that SSNA, comprising cutaneous vasoconstrictor and sudomotor activity, increases with both positively charged and negatively charged emotional images.
Journal ArticleDOI
Real-time imaging of cortical areas involved in the generation of increases in skin sympathetic nerve activity when viewing emotionally charged images.
Luke A. Henderson,Alexandra Stathis,Alexandra Stathis,Cheree James,Rachael Brown,Skye McDonald,Vaughan G. Macefield,Vaughan G. Macefield +7 more
TL;DR: These data reveal for the first time, cortical and subcortical sites involved in generating SSNA changes during emotions, and increases in signal intensity during increases in SSNA occurred in a number of brain regions.
Journal ArticleDOI
Mal de Debarquement Syndrome: a survey on subtypes, misdiagnoses, onset and associated psychological features.
Viviana Mucci,Josephine M. Canceri,Rachael Brown,M. Dai,S. Yakushin,Shaun R. Watson,A. Van Ombergen,Vedat Topsakal,P. Van de Heyning,Floris L. Wuyts,Cherylea J. Browne,Cherylea J. Browne +11 more
TL;DR: This was the first attempt to evaluate the diagnostic differences between MdDS subtypes and to propose a set of comprehensive diagnostic guidelines for both Md DS subtypes.
Journal ArticleDOI
Skin sympathetic nerve activity in humans during exposure to emotionally-charged images: sex differences.
TL;DR: It is concluded that SSNA increases with both positively-charged and negatively-charged emotional images, yet sex differences are present.
Journal ArticleDOI
Selective activation of muscle and skin nociceptors does not trigger exaggerated sympathetic responses in spinal-injured subjects.
TL;DR: While hypertonic saline injected into muscle or skin induces strong pain, cutaneous vasoconstriction and sweat release in able-bodied subjects, the authors saw no evidence of exaggerated sympathoexcitation when these same noxious stimuli were delivered below lesion in subjects with SCI, suggesting that certain types of somatic noxious input may not trigger autonomic dysreflexia.
