“…Indeed, according to some authors, there is a strong correlation between the sympathetic activity and M1 (Schlindwein et al, 2008) and DLPFC (Henderson et al, 2012). However, according to our review, other brain areas, apart from M1 and DLPFC also showed promising effects in modulating ANS function, such as parietal (Silber et al, 2000;van Honk et al, 2003;Lai et al, 2010), occipital (Silber et al, 2000;Vernieri et al, 2009), frontal (Silber et al, 2000), vertex (Macefield et al, 1998;Yoshida et al, 2001) and temporal (Montenegro et al, 2011) regions.…”

“…the cortical targets which reached a level A of evidence for rTMS interventions; figure 1a) may influence cardiovascular autonomic functions [120,121], and that both cortical regions showed associations with sympathetic activity in humans [122,123], similar effects could consequently be expected in subjects who underwent several sessions of rTMS on these cortical targets. Some early studies confirmed this hypothesis: for example, Udupa et al [124] treated daily for two weeks a group of 27 depressed patients by high-frequency rTMS of the left DLPFC, for a total of 18 000 pulses.…”

Cardiovascular and cerebrovascular regulatory systems are vital control mechanisms responsible for guaranteeing homeostasis and are affected by respiration. This work proposes the investigation of cardiovascular and cerebrovascular control systems and the nonlinear influences of respiration on both regulations through joint symbolic analysis (JSA), conditioned or unconditioned on respiration. Interactions between cardiovascular and cerebrovascular regulatory systems were evaluated as well by performing correlation analysis between JSA indexes describing the two control systems. Heart period, systolic and mean arterial pressure, mean cerebral blood flow velocity and respiration were acquired on a beat-to-beat basis in 13 subjects experiencing recurrent syncope episodes (SYNC) and 13 healthy individuals (non-SYNC) in supine resting condition and during head-up tilt test at 60° (TILT). Results showed that JSA distinguished conditions and groups, whereas time domain parameters detected only the effect of TILT. Respiration affected cardiovascular and cerebrovascular regulatory systems in a nonlinear way and was able to modulate the interactions between the two control systems with different outcome in non-SYNC and SYNC groups, thus suggesting that the analysis of the impact of respiration on cardiovascular and cerebrovascular regulatory systems might improve our understanding of the mechanisms underpinning the development of postural-related syncope.

“…Such measures are widely used by neuroscientists to measure emotional arousal (Salimpoor, Benovov, Larcher, Dagher and Zatorre 2011). Functional magnetic imaging is also increasingly available to measure emotional arousal and the intensity of such emotional arousal (Henderson et al 2012). While several of these may be viable options, some could be prohibitively expensive to utilize and/or require subjects to travel to a laboratory setting, which could restrict full-time employee involvement.…”
