aim and background: the behavioral inhibition system (bis) and the behavioral activation system (bas) are considered as factors to verify the effects of personality significance on cortical activity. the present study explored the effects of the bis and bas on frontal asymmetry in response to affect stimuli. methods and materials: this study included 36 individuals (18 with high bas sensitivity...
Background and Aim: Pain management is very important in neonates. The use of non- pharmacological methods can be effective in reducing pain in neonates. The current study aimed at assessing the effect of non-nutritive sucking on the physiological and behavioral pain responses to B Hepatitis vaccine in term infants. Materials and Methods: In this clinical- trial study in Ninth Day Hospital o...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
Organisms react to environmental challenges by activating a coordinated set of brain-body responses known as the stress response. These physiological and behavioral countermeasures are, in large part, regulated by the neuroendocrine hypothalamic-pituitary-adrenal (HPA) axis. Normal functioning of the HPA axis ensures that an organism responds appropriately to altered environmental demands, repr...
OBJECTIVE Although many methods for pain assessment in newborns are available, none of them are widely accepted. Our aim was to answer the question: do newborns respond similarly to different painful procedures? METHODS Sixty term newborns were involved in non-randomized prospective study. They were classified into 2 groups: Group A (n=30) who needed intubation and Group B (n=30) who necessit...
Exercise is known to be rewarding and have positive effects on mental and physical health. Excessive exercise, however, can be the result of an underlying behavioral/physiological addiction. Both humans who exercise regularly and rodent models of exercise addiction sometimes display behavioral withdrawal symptoms, including depression and anxiety, when exercise is denied. However, few studies h...
background: hypoactive sexual desire disorder is the most common sexual disorder among women, which interferes with their various functions. activity of brain-behavioral and psychological distress systems are considered among factors affecting sexual function. objectives: the present study aimed to compare women with hypoactive sexual desire and normal women in terms of brain-behavioral and psy...
Mild psychological stressors provoke an acute rise in core temperature (T(C)), stimulate the hypothalamo-pituitary-adrenocortical (HPA) axis, and induce various stress-related behaviors. In the present study, we examined the effect of ablation of the anteroventral third ventricle region (AV3V) on both physiological and behavioral responses to a novel environment. T(C) was monitored in male Spra...
Functional magnetic resonance imaging (fMRI) is based on correlating blood oxygen-level dependent (BOLD) signal fluctuations in the brain with other time-varying signals. Although the most common reference for correlation is the timing of a behavioral task performed during the scan, many other behavioral and physiological variables can also influence fMRI signals. Variations in cardiac and resp...
In recent years there have been a number of important advances in the understanding of cellular mechanisms related to olfactory function. Hypotheses regarding the complex relationships among odorant structure, physiological activity and behavioral outcome generated by these findings, however, remain largely untested due to a paucity of psychophysical data on stimulus discrimination in the same ...
