When tonic cardiac vagal tone predicts changes in phasic vagal tone: the role of fear and perceptual load.
We examined the relationship between tonic--a correlate of self-regulatory functioning--and phasic cardiac vagal activity (indexed by heart rate variability; HRV) during a selective attentional task with varying levels of load. Participants detected a target letter among letter strings superimposed on either fearful or neutral face distractors. Letter strings consisted of six target letters und...

Background and Purpose: Basically, The muscle spindle is innervated by γ – fibers, γ – fibers are divided into phasic and tonic groups on the basis of their function. Ït is believed that phasic one γ innervate all the muscle spindle fibers where as tonic one innervate only tonic muscle spindle fibers and phasic of type two. The purpose of this study was to observe the fiber activity during ph...
متن کاملTonic and phasic co-variation of peripheral arousal indices in infants
Tonic and phasic differences in peripheral autonomic nervous system (ANS) indicators strongly predict differences in attention and emotion regulation in developmental populations. However, virtually all previous research has been based on individual ANS measures, which poses a variety of conceptual and methodlogical challenges to comparing results across studies. Here we recorded heart rate, el...
متن کامل1 Running head : ASTON - JONES FRAMEWORK REVIEW
Differential Susceptibility Theory explains long-term associations between neurobiological sensitivity and cognitive outcomes, but no comparable theoretical framework exists to understand how neurobiological sensitivity and cognitive performance inter-relate on shorter time-frames. Here, we evaluate a framework proposed by Aston-Jones and colleagues, building on the Yerkes-Dodson model, to unde...
متن کاملUpper airway muscle activity in normal women: influence of hormonal status.
Obstructive sleep apnea is a disorder with a strong male predominance. One possible explanation could be an effect of female hormones on pharyngeal dilator muscle activity. Therefore, we determined the level of awake genioglossus electromyogram (EMGgg) and upper airway resistance in 12 pre- and 12 postmenopausal women under basal conditions and during the application of an inspiratory resistive...
