To investigate whether emotional arousal affects memorial feature binding, we had participants complete a short-term source-monitoring task-remembering the locations of four different pictures over a brief delay. On each trial, the four pictures were all either high arousal, medium arousal, or low arousal. Memory for picture-location conjunctions decreased as arousal increased. In addition, sou...

The physiological basis for the interaction of selective attention and arousal is not clearly understood. Here we present evidence in humans that specifically implicates the thalamus in this interaction. We used functional magnetic resonance imaging to measure brain activity during the performance of an attentional task under different levels of arousal. Activity evoked in the ventrolateral tha...

BACKGROUND Below average heart rate variability (HRV) has been associated with sexual arousal dysfunction and overall sexual dysfunction in women. Autogenic training, a psychophysiologic relaxation technique, has been shown to increase HRV. In a recent study, sexually healthy women experienced acute increases in physiologic (ie, genital) and subjective sexual arousal after 1 brief session of au...

Functional infrared thermal imaging (fITI) is considered a promising method to measure emotional autonomic responses through facial cutaneous thermal variations. However, the facial thermal response to emotions still needs to be investigated within the framework of the dimensional approach to emotions. The main aim of this study was to assess how the facial thermal variations index the emotiona...

The sophisticated analysis of gestures and vocalizations, including assessment of their emotional valence, helps group-living primates efficiently navigate their social environment. Deficits in social information processing and emotion regulation are important components of many human psychiatric illnesses, such as autism, schizophrenia and social anxiety disorder. Analyzing the neurobiology of...

INTRODUCTION Few studies have examined how sexual arousal influences healthy premenopausal women's hormones, limiting our understanding of basic physiology and our ability to transfer knowledge from clinical and nonhuman populations. AIM To examine how sexual arousal and steroid hormones (testosterone [T], cortisol [C], estradiol [E]) were linked, to see whether hormone levels influenced and/...

Abstract Sleep and arousal are both important for animals. The neurotransmitter acetylcholine (ACh) has long been found to promote sleep in mammals, an apparent paradox which also exist flies, causing much confusion understanding arousal. Here, we have systematically studied all 13 ACh receptors (AChRs) Drosophila understand mechanisms underlying function We that exogenous stimuli-induced was d...

Purpose – This paper aims to test a theoretical framework that explains arousal congruency effects on consumer perceptions of intrinsically pleasant service environments. Design/methodology/approach – A 3 (low and high target-arousal manipulation plus control group) by 3 (low, medium and high actual arousal) true experimental design was used to test our research hypotheses in a café context. Th...

OBJECTIVE To investigate the relationship between arousal and nocturnal heart rate variability (HRV) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS Twenty-seven patients with moderate to severe OSAHS who underwent overnight polysomnography (PSG) were enrolled, excluding patients with cardiopulmonary and nervous system diseases. An hour continuous PSG monitoring in...

Although there is an extensive amount known about specific sensory and motor functions of the vertebrate brain, less is understood about the regulation of global brain states. We have recently proposed that a function termed generalized arousal (Ag) serves as the most elemental driving force in the nervous system, responsible for the initial activation of all behavioral responses. An animal wit...
