In general, cardiac regulation is dominated by the sympathetic and parasympathetic nervous systems in men and women, respectively. Our recent study had revealed sex differences in the forebrain network associated with sympathoexcitatory response to baroreceptor unloading. The present study further examined the sex differences in forebrain modulation of cardiovagal response at the onset of isometric exercise. Forebrain activity in healthy men (n = 8) and women (n = 9) was measured using…

Sex Differences in Cardiac Baroreflex Sensitivity after Isometric Handgrip Exercise
TLDR
Acute IHG exercise increases cBRS and cardiac vagal activity in healthy young subjects, but the magnitude and the time course of changes in cB RS differ between men and women.
Sex differences in insular gyri responses to the cold pressor challenge
TLDR
Although distinct transient male-female differences in fMRI responses appeared during the cold pressor, no sex differences in ASG lateralization emerged, suggesting that the previously found sex differences may not solely relate to regulating blood pressure responses.
Sex differences in insular cortex gyri responses to a brief static handgrip challenge
TLDR
The anterior insula plays a greater role in cardiovascular regulation than posterior areas during a predominantly parasympathetic withdrawal challenge, with opposite lateralization between sexes.
Sex Differences in Insular Cortex Gyri Responses to the Valsalva Maneuver
TLDR
Sex differences in autonomic regulation may underlie cardiovascular disease variations between females and males, and fMRI responses to a series of four Valsalva maneuvers confirm the anterior and right-sided sympathetic dominance of the insula.
Sex differences in the neural correlates of autonomic arousal: a pilot PET study.
Cortical and brain stem changes in neural activity during static handgrip and postexercise ischemia in humans.
TLDR
The data support that the metaboreflex is mediated by the medulla, whereas the somatosensory, insular, and anterior cingulate cortices are involved in the sensory and affective components of the maneuver.
Apnea-Induced Cortical BOLD-fMRI and Peripheral Sympathoneural Firing Response Patterns of Awake Healthy Humans
TLDR
Findings identify a neuroanatomical substrate to guide future investigations into central mechanisms contributing to disorders characterized by elevated basal MSNA and exaggerated sympathetic responses to simulated apneas such as sleep apnea and heart failure.

The relation of ventromedial prefrontal cortex activity and heart rate fluctuations at rest
TLDR
The findings confirm data obtained in animals describing the vmPFC as an important forebrain structure of the central autonomic network and an influence of thevmPFC in the cortical generation of efferent vagal activity.

Forebrain neural patterns associated with sex differences in autonomic and cardiovascular function during baroreceptor unloading.
TLDR
Men demonstrated greater BOLD signal reductions in the right amygdala, left insula, ventral anterior cingulate, and ventral medial prefrontal cortex vs. women, and this may have contributed to the elevated HR and sympathetic responses observed in men during 35 mmHg LBNP.
Influences of gender on sympathetic nerve responses to static exercise.
TLDR
It is concluded that, during nonischemic static exercise, sympathetic neural outflow is less in women compared with men, and this response is due to an attenuated metaboreflex in women.
Gender affects sympathetic and hemodynamic response to postural stress.
TLDR
Data point to gender-specific autonomic responses to cardiovascular stress in women through differences in sympathetic reflex responses to head-up tilt between genders.
Ventral medial prefrontal cortex and cardiovagal control in conscious humans
Microneurographic studies of the mechanisms of sympathetic nerve responses to static exercise in humans.
TLDR
Data indicate that muscle sympathetic nerve activity is increased by stimulation of chemically sensitive muscle afferents during static exercise in humans.
Evidence for central command activation of the human insular cortex during exercise.
TLDR
Findings provide evidence that there are rCBF changes within regions of the insular and anterior cingulate cortexes related to central command per se during handgrip exercise, independent of metaboreflex activation and blood pressure elevation.
Cortical regions associated with autonomic cardiovascular regulation during lower body negative pressure in humans
TLDR
The brain regions associated with lower body negative pressure (LBNP)‐induced baroreflex control using functional magnetic resonance imaging with blood oxygen level‐dependent (BOLD) contrast in eight healthy male volunteer subjects provided the first evidence for the identification of the cortical network involved specifically with barore Flex‐mediated autonomic cardiovascular function in conscious humans.

TLDR
The hypothesis that women have less responsiveness in mechanisms that underlie blood pressure regulation under orthostatic challenge is supported, and lower LBNP tolerance in females was associated with reduced HR response to carotid baroreceptor stimulation and lower baseline cardiac vagal activity.
Neural sites involved in the sustained increase in muscle sympathetic nerve activity induced by inspiratory capacity apnea: a fMRI study.
TLDR
Functional magnetic resonance imaging was used to define the loci and time course of activation ofactivation of different brain areas for the Valsalvsa maneuver, and significant signal increases emerged in multiple areas, including the rostral lateral medulla, cerebellar nuclei, anterior insula, dorsal hypothalamus, anterior cingulate, and lateral prefrontal cortexes.
Gender differences in autonomic cardiovascular regulation: spectral, hormonal, and hemodynamic indexes.
TLDR
The results of this study suggest a predominance of sympathetic vascular regulation in men compared with a dominant parasympathetic influence on heart rate regulation in women.
