SummaryUsing delayed auditory feedback (delay 0.175 s) a standardized form of mental stress was investigated in 8 healthy male volunteers. After a resting period and a period of undelayed reading, the volunteers were exposed for 5 min to the DAF stress. During the DAF period heart rate increased by 10% and systolic and diastolic blood pressure increased by 9% and 18%, respectively. As a measure of acute sympathetic activation, plasma concentrations of norepinephrine and epinephrine rose by 68…

Cardiac parasympathetic regulation in obese women with binge eating disorder
TLDR
Mental challenge led to an augmented reduction of HRV-HF in obese binge eaters, which was linked to the binge eating frequency and hunger perception, but not to psychiatric comorbidity.
Delayed Auditory Feedback for speech disorders
Stuttering is fluid impairment in verbal speech which will be determined based on the involuntary repetitions and prolongations, either vowel or voiceless. A variety of methods is available to aid
Rhythmic versus phonemic interference in delayed auditory feedback.
PURPOSE Delayed auditory feedback (DAF) of a speaker's voice disturbs normal speech production. Various traditional theories assume that the content of the delayed feedback signal interferes with the
The Potential for a Speech Brain–Computer Interface Using Chronic Electrocorticography
TLDR
This review discusses and outlines the current state-of-the-art for speech BCI and explores what aspeech BCI using chronic ECoG might entail and what the challenges for the translation of speech BCIs to clinical populations remain.
Altered prazosin pharmacokinetics in congestive heart failure
TLDR
The finding of higher prazosin plasma concentrations in patients with refractory heart failure demonstrates the need for close monitoring of these individuals following administration of the drug in the treatment of chronic congestive heart failure.
DAVID: An open-source platform for real-time emotional speech transformation: With 25 applications in the behavioral sciences
TLDR
An open-source software platform that transforms the emotions expressed by speech signals using audio effects like pitch shifting, inflection, vibrato, and filtering, and a list of twenty-five experimental ideas applying this new tool to important topics in the behavioral sciences is provided.
The relationship between high and low trait psychological stress and serum indicators of stress
TLDR
There was no significant difference between high and low psychological stress subjects in either age group with any of the serum indicators of stress.

TLDR
The results of this investigation proved that adrenaline excretion is a sensitive index of individual responses to psychological stressors and its level in urine corresponds to the degree of emotional arousal.
The effects of alcohol and variable amount of cognitive stress on the estimation of time.
TLDR
Alcohol was found to lead to underestimation (a verbal estimate smaller than a given standard) in the absence of stress, but did not affect the estimates when stress was involved; a pronounced central effect was found under maximal stress which was not affected by alcohol.
Correlation between increased dopamine-β- hydroxylase activity and catecholamine concentration in plasma: Determination of acute changes in sympathetic activity in man
TLDR
Increased sympathetic activity in man can be estimated in vivo as changes in DBH and/or CA concentration in plasma in contrast to a rapid decrease in sympathetic activity, which is directly reflected only by a rapid fall in the plasma concentrations of CA.

The effect of standing and exercise on plasma catecholamines, serum insulin, and serum gastrin.
TLDR
It is concluded that a moderate increase in adrenergic activity has no influence on glucose-stimulated insulin secretion.

TLDR
There was no evidence that patients with sustained hypertension have an increased production of catecholamines either at rest or under 'stress'.
Comparative effect in human subjects of chlordiazepoxide, diazepam, and placebo on mental and physical performance

Plasma levels of norepinephrine.
TLDR
Sympathetic nervous activity and the ability of the sympathetic nervous system to respond to a uniform stimulus are studied in hypertensive and normotensive subjects and a survey of the plasma levels of norepinephrine in a variety of neurologic disorders is given.
