Sympathetic and parasympathetic innervation of pupillary dilation during sustained processing.
The contributions of separate sympathetic and parasympathetic pathways to pupillary dilation during a sustained processing task were studied through environmental and pharmacological manipulations. In Experiment 1, 22 healthy volunteers (11 female) performed a serial Subtract 7 task while pupil diameter was recorded both during moderate room light and in darkness. In a control for verbalization...
متن کاملDistinct contributions of the sympathetic and parasympathetic pathways to the pupillary response during emotional processing
parameters. As a first strategy, we introduce a kernel-based approach to learn the DBS parameters from VTA data. Our data-driven methodology employs a kernel-based eigendecomposition from pair-wise Hamming distances to extract relevant VTA patterns into a low-dimensional space. Further, DBS parameter estimation is carried out by employing a kernelbased multi-output regression and classification...
متن کاملModulation of urethral alpha-sympathetic by parasympathetic before and following bethanechol chloride injection.
INTRODUCTION AND OBJECTIVES Chagas' disease causes specific parasympathetic denervation and in its digestive clinic form promotes also functional alterations in bladder. Thus, the aim was to investigate the existence of balance between sympathetic and parasympathetic systems in lower urinary tract, as occurs in other organs. We verified the urethral closing pressure before and following parasym...
متن کاملIncreased sympathetic and decreased parasympathetic cardiovascular modulation in normal humans with acute sleep deprivation.
Cardiovascular autonomic modulation during 36 h of total sleep deprivation (SD) was assessed in 18 normal subjects (16 men, 2 women, 26.0 +/- 4.6 yr old). ECG and continuous blood pressure (BP) from radial artery tonometry were obtained at 2100 on the first study night (baseline) and every subsequent 12 h of SD. Each measurement period included resting supine, seated, and seated performing comp...
متن کاملSympathetic-parasympathetic interactions in the heart.
We determined the influence of differences in the time of initiation of sympathetic and vagal stimulation (both at 10 Hz) on the cardiac autonomic interactions in 16 open-chest anesthetized dogs. We always ended the concurrent sympathetic and vagal stimulations simultaneously. Sympathetic stimulation alone for 1 minute increased heart rate by 90±7 (mean+SEM) beats per minute, and vagal stimulat...
