Owing to fierce competition in the textile market, the prices charged cannot be too high.

Astrocytic calcium waves:unveiling their roles in sleep and arousal modulation

Neuron-astrocyte interactions are vital for the brain’s connectome.Understanding astrocyte activities is crucial for comprehending the complex neural network,particularly the population-level functions of neurons in different cortical states and associated behaviors in mammals.Studies on animal sleep and wakefulness have revealed distinct cortical synchrony patterns between neurons.Astrocytes,outnumbering neurons by nearly fivefold,support and regulate neuronal and synaptic function.Recent research on astrocyte activation during cortical state transitions has emphasized the influence of norepinephrine as a neurotransmitter and calcium waves as key components of ion channel signaling.This summary focuses on a few recent studies investigating astrocyte-neuron interactions in mouse models during sleep,wakefulness,and arousal levels,exploring the involvement of noradrenaline signaling,ion channels,and glutamatergic signaling in different cortical states.These findings highlight the significant impact of astrocytes on large-scale neuronal networks,influencing brain activity and responsiveness.Targeting astrocytic signaling pathways shows promise for treating sleep disorders and arousal dysregulation.More research is needed to understand astrocytic calcium signaling in different brain regions and its implications for dysregulated brain states,requiring future human studies to comprehensively investigate neuron-astrocyte interactions and pave the way for therapeutic interventions in sleep-and arousal-related disorders.

Provoking Buying Behaviors Amid Crises:Unfolding the Underlying Mechanisms of Psychological Impairments

Crises in the past have caused devastating,long-lasting impacts on the global economy.The after-effects always bring some dynamic and rigorous challenges for businesses and governments.Such challenges have always been a point of discussion for scholars.The recent COVID-19 pandemic emaciated the global economy,leaving everyone mired in uncertainty,fear,and psychological impairments.One of the headwind features utilized by consumers during pandemic was panic buying(PB),which must be explored in various contexts for policymakers and practitioners.To address this gap,this study deployed a moderated mediation mechanism,integrating the health belief model(HBM)and competitive arousal theory(CAT)to excavate the notions underlying PB with the intrusion of evolved real-time psychological disorders:intolerance of uncertainty(IU)and cyberchondria(CYC).The study was conducted as a natural experiment in a South Asian developing economy using online surveys.It found that health beliefs—perceived severity(PSV)and perceived susceptibility(PSC)—positively impact perceived arousal(PA),which causes PB,and that PA has a sturdy mediator role.Moreover,in the relationship between health beliefs and arousal,the different psychological disorders were found to have significant moderating roles The study findings can help mitigate risk uncertainties and panic situations and thus contribute to consumers’wellbeing.

What emotion dimensions can affect working memory performance in healthy adults?A review

Due to the critical roles of emotion and working memory in our daily activities,a great deal of attention has been given to how emotion influences working memory performance.Although the association between emotion and working memory is relatively well established,whether mood enhances or impairs working memory performance remains controversial.The present review provides a relatively representative overview of the research on the effect of different dimensions of emotion on working memory among healthy adults spanning a 30-year period.The findings show that the valence,arousal and motivational dimensions of emotion could all exert an impact on working memory performance.The impact of emotion on working memory might be modulated by task relevance,emotion type,working memory paradigms and individual differences.The vast majority of the studies regarding the effect of emotion on working memory performance focused on the impact of negatively valenced affect and yielded highly contradictory findings.The impacts of arousal and motivation on working memory have been less explored,and inconsistent findings have also been reported.Possible explanations are discussed.Considerable research on the effect of certain dimensions of emotion on working memory has suffered from a lack of control of other emotional dimensions,and different aspects of working memory have been investigated by various paradigms.Directions for further studies should include the exploration of specific dimensions of emotion on different aspects of working memory,with the other dimensions being well controlled.

USE OF PULSE TRANSIT TIME AS A MEASURE OF AUTONOMIC AROUSALS IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA

Objective To evaluate the feasibility of pulse transit time (PTT) arousals as an index of sleep fragmentation in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods Individuals referred for evaluation of possible OSAHS underwent overnight polysomnography (PSG). Three conventional indices of sleep fragmentation [electroencephalography (EEG) arousals, apnea/hypopnea index (AHI), oxygen desaturation index (ODI)], PTT arousals, and Epworth sleepiness scale (ESS) were compared. Results PTT arousals were positively correlated with EEG arousals (r= 0.746, P<0.001), AHI (r= 0.786, P<0.001), and ODI (r= 0.665, P<0.001), respectively. But, both PTT arousals and EEG arousals had no correlation with ESS (r= 0.432, P=0.201; r= 0.196, P=0.591, respectively). Conclusion PTT arousals are correlated well with other standard measures estimating severity of OSAHS and potentially a non-invasive marker with which to measure the sleep fragmentation in patients with OSAHS.

The Effect of Emotional Conflict on Attention Allocation: An Event-Related Potential Study

Attention allocation research frequently focuses on the valence of emotion. However, there is increasing evidence to indicate that arousal may be more relevant at some stages of affective processing. The present study employed a combined priming and cue-target paradigm and examined event-related potentials (ERPs) in order to explore the effects of emotional conflict of arousal on attention allocation. The background context of arousal was manipulated (using photos of facial expressions) while subjects performed a cognitive task in which a central arrow cue indicated the location of a peripheric target square, and a response was made according to the direction of the square. There was no main effect between incongruent emotion and congruent emotion in the response time, which means the resolution of the emotional conflict facilitate the participant behavioral response. There was a main effect of different emotional states on ERP component. In the present study, incongruent arousal also triggered greater positive potential compared with congruent arousal.

Prenatal nicotine alters development of the laterodorsal tegmentum:Possible role for attention-deficit/hyperactivity disorder and drug dependence

As we cycle between the states of wakefulness and sleep,a bilateral cholinergic nucleus in the pontine brain stem,the laterodorsal tegmentum(LDT),plays a critical role in controlling salience processing,attention,behavioral arousal,and electrophysiological signatures of the sub-and microstates of sleep.Disorders involving abnormal alterations in behavioral and motivated states,such as drug dependence,likely involve dysfunctions in LDT signaling.In addition,as the LDT exhibits connectivity with the thalamus and mesocortical circuits,as well as receives direct,excitatory input from the prefrontal cortex,a role for the LDT in cognitive symptoms characterizing attention-deficit/hyperactivity disorder(ADHD)including impulsivity,inflexibility,and dysfunctions of attention is suggested.Prenatal nicotine exposure(PNE)is associated with a higher risk for later life development of drug dependence and ADHD,suggesting alteration in development of brain regions involved in these behaviors.PNE has been shown to alter glutamate and cholinergic signaling within the LDT.As glutamate and acetylcholine are major excitatory mediators,these alterations would likely alter excitatory output to target regions in limbic motivational circuits and to thalamic and cortical networks mediating executive control.Further,PNE alters neuronal development and transmission within prefrontal cortex and limbic areas that send input to the LDT,which would compound effects of differential processing within the PNE LDT.When taken together,alterations in signaling in the LDT are likely to play a role in negative behavioral outcomes seen in PNE individuals,including a heightened risk of drug dependence and ADHD behaviors.

Gazing through the bubble:an experimental investigation into financial risk‑taking using eye‑tracking

Eye tracking can facilitate understanding irrational decision-making in contexts such as financial risk-taking.For this purpose,we develop an experimental framework in which participants trade a risky asset in a simulated bubble market to maximize individual returns while their eye movements are recorded.Returns are sensitive to eye movement dynamics,depending on the presented visual stimuli.Using eye-tracking data,we investigated the effects of arousal,attention,and disengagement on individual payoffs using linear and nonlinear approaches.By estimating a nonlinear model using attention as a threshold variable,our results suggest that arousal positively influences trading returns,but its effect becomes smaller when attention exceeds a certain threshold,whereas disengagement has a higher negative impact on reduced attention levels and becomes almost irrelevant when attention increases.Hence,we provide a neurobehavioral metric as a function of attention that predicts financial gains in boomand-bust scenarios.This study serves as a proof-of-concept for developing future psychometric measures to enhance decision-making.

The influence of core affect on cyclo-ergometer endurance performance:Effects on performance outcomes and perceived exertion

Background:Core affect is defined as the most general affective construct consciously accessible that is experienced constantly.It can be experienced as free-floating(mood)or related to prototypical emotional episodes.The aim of this study was to examine the influence of pleasant and unpleasant core affect on cyclo-ergometer endurance performance.Specifically,we considered the influence of pleasant and unpleasant core affect on performance outcomes(i.e.,time to task completion)and rate of perceived exertion(RPE;Borg Scale,category ratio-10)collected during the task.Methods:Thirty-one participants aged 20-28 years were recruited.Core affect was randomly elicited by 2 sets of pleasant and unpleasant pictures chosen from the international affective picture system.Pictures were displayed to participants during a cyclo-ergometer performance in 2 days in a counterbalanced order.RPE was collected every minute to detect volunteers’exhaustion.Results:The study sample was split into 2 groups.Group 1 comprised participants who performed better with pleasant core affect,whereas Group 2 included participants who performed better with unpleasant core affect.Mixed between-within subjects analysis of variance revealed a significant 2(group)×2(condition)×5(isotime)interaction(p=0.002,ηp^2=0.158).Post hoc comparisons showed that participants who obtained better performance with pleasant core affect(pleasant pictures;Group 1)reported lower RPE values at 75%of time to exhaustion in a pleasant core affect condition compared to an unpleasant core affect condition.On the other hand,participants who obtained better performance with unpleasant core affect(unpleasant pictures;Group 2)reported lower RPE values at 75%and 100%of time to exhaustion in an unpleasant core affect condition.Conclusion:Findings suggest differential effects of pleasant and unpleasant core affect on performance.Moreover,core affect was found to influence perceived exertion and performance according to participants’preferences for pleasant or unpleasant core affect.
