Cardiovascular Reflexes Activity and Their Interaction during Exercise
"... Cardiac output and arterial blood pressure increase during dynamic exercise notwithstanding the exercise-induced vasodilation due to functional sympatholysis. These cardiovascular adjustments are regulated in part by neural reflexes which operate to guarantee adequate oxygen supply and by-products ..."

Resetting Important? The "resetting" of the arterial baroreflex is essential to evoke and maintain an effective autonomic nervous system modulation and an adequate cardiovascular adjustment to exercise. In exercising dogs, acute denervation of baroreceptors leads to overnormal increase in arterial
Perspectives in Diabetes Autonomic Mediation of Glucagon Secretion During Hypoglycemia Implications for Impaired a-Cell Responses in Qpe 1 Diabetes
, 1998
"... This article examines the role of the autonomic nervous system in mediating the increase of glucagon secretion observed during insulin-induced hypoglycemia (IIH). In the first section, we briefly review the importance of the a-cell response in recovery from hypoglycemia under both physiologic condi ..."

. These findings provide an alternative to the interpretation that hypoglycemia directly stimulates the a-cell. Evidence in vivo suggests that part of the suppression of endogenous insulin secretion seen during IIH is due to activation of the autonomic nervous system. The evidence for the effect
C: Nocturnal exposure to intermittent 60 Hz magnetic fields alters human cardiac rhythm. Bioelectromagnetics
, 1998
"... Heart rate variability (HRV) results from the action of neuronal and cardiovascular reflexes, including those involved in the control of temperature, blood pressure and respiration. Quantitative spectral analyses of alterations in HRV using the digital Fourier transform technique provide useful in ..."

Running Head: PSYCHOPHYSIOLOGY OF EXCLUSION, FILMS Psychophysiology of Exclusion, Films 1 THE PSYCHOPHYSIOLOGICAL RESPONSES TO SOCIAL EXCLUSION AND AFFECTIVE FILMS
, 2008
"... This research studies the effects of viewing a positive or a negative (violent) film clip on the psychophysiological responses to social exclusion. While previous research has found impressive behavioral overlap between social exclusion and violent media, these two stimuli have not been studied toge ..."

The underlying dynamics of this cardiovascular response show that the decreased heart rate resulted from an attenuation of autonomic nervous system activity during the social exclusion period.

Clonidine Improves Spontaneous Baroreflex Sensitivity in Conscious Mice Through Parasympathetic Activation
"... Abstract—-2 Adrenoceptors are important in baroreflex regulation. We tested the impact of -2 adrenoceptors on heart rate variability (HRV) and spontaneous baroreflex sensitivity (BRS) in conscious mice with telemetry (TA11PA-C20). Baseline beat-to-beat measurements (2 hours between 8:00 AM to 12:00 ..."

) but not with metoprolol (4 mg/kg plus 50 mg/kg of clonidine). These data suggest that -2 adrenoceptors exert a regulatory influence on autonomic cardiovascular control and baroreflex function. The effect of clonidine on baroreflex HR regulation is mediated by the parasympathetic nervous system. These murine data fit well
Motivational Processing and Choice Behavior During Television Viewing: An Integrative Dynamic Approach.”
- Journal of Communication

"... This study was designed to further our understanding of the central role of motivational activation in mediated information processing and media choice. To do this, a dynamic model was developed to formalize the dynamic effects of three basic motivational input variables (arousing content, positivi ..."

Each of the outputs is influenced by three basic motivational input variables, their dynamic interactions, and feedback from its own previous responses. The feedback effect term is critical
