TL;DR: It is indicated that a large component of the variance in SCRs can be explained by one response function per individual, and there was no evidence for nonlinear interactions among evoked responses that depended on their temporal overlap.

TL;DR: Strong evidence is presented that brain networks, ranging from simple nets of interconnected neurons up to macroscopic networks of brain areas display the typical features of complex systems: high clustering, short path lengths, skewed degree distributions, presence of hubs, assortative mixing and the presence of modules.

TL;DR: Topographically analyzed top-down ANT effects on visual event-related potential morphology in 44 healthy participants and suggested attentional mechanisms of alerting and orienting are employed simultaneously at early stages of the visual processing stream to amplify perceptual discrimination and load onto the same ERP component.

TL;DR: A simple measure of sympathetic arousal is derived, using a convolution model of how sudomotor bursting causes fluctuations in skin conductivity, and it is shown that it is a better predictor of autonomic arousal, relative to conventional measures.

TL;DR: Depression is a risk factor for both onset of cardiovascular disease (CVD) and increased morbidity and mortality for those with CVD and few studies have examined the effects of psychological interventions on HRV.

TL;DR: The construction of an olfactometer is detailed that is constructed almost exclusively with "off-the-shelf" parts, requires little technical knowledge to build, has relatively low price tags, and is controlled by E-Prime, a turnkey-ready and easily-programmable software commonly used in psychological experiments.

TL;DR: Emotion effects in ERPs were evident in a late positive complex (LPC) for negative, high-arousal words in comparison to neutral words, and the LPC was unaffected by pure arousal variation when valence was controlled for, indicating the importance of valence for this emotion-related ERP effect.

TL;DR: Evidence that regular physical activity selectively improves executive function, as represented by the task switching paradigm, is presented, even during young adulthood is presented.

TL;DR: It was found that eight of the ten subjects showed a relative focal bilateral increase of [oxy-Hb] in the dorsolateral prefrontal cortex (DLPFC) in parallel with a decrease in the medial area of the anterior cortex (APFC).

TL;DR: The results show that people are indeed able to alter the power in the gamma band if provided with neurofeedback, and the increase of gamma band power was related to a decrease of binding costs and an increase in intelligence, suggesting that the control of feature binding and intelligence share a common underlying mechanism.

TL;DR: It is suggested that the diurnal rhythm and awakening response of salivary cortisol are significantly reduced in older adults and the associations between anxiety, depression and social support and diurnal cortisol vary with age.

TL;DR: The results support a reconsideration of the roles of N2 and P3 in all inhibition and conflict tasks, and the Go/NoGo task in particular.

TL;DR: Raising CO2 levels by means of therapeutic capnometry has proven beneficial effects in both panic disorder and asthma, and the reversing of hyperventilation has emerged as a potent mediator for reductions in panic symptom severity and treatment success.

TL;DR: The effect of order of the HT and BN consultations on the students' stress levels suggests an additional impact of novelty and habituation, and unfamiliarity with the patient may enhance the stressfulness of the task of breaking bad news.

TL;DR: Differences in event-related potential (ERP) parameters were observed in auditory, cognitive and aesthetic processing of chord cadences between experts and laypersons, indicating a stronger reliance on internal affective states while forming a judgment.

TL;DR: Dividing the group by median age revealed that middle-aged adults reduced RSA to a greater degree than their younger counterparts in the context of equivalent performance across groups, suggesting that performance of executive function tasks that evoke attentional control may depend in part on the responsiveness of autonomic control parameters via age-dependent mechanisms.

TL;DR: Adults with ASD did not show significantly atypical processing of facial familiarity and repetition in an ERP paradigm, despite showing significantly poorer performance than controls on a behavioral test of face memory.

TL;DR: It is concluded that endurance training not only increases exercise tolerance due to its influence on metabolism but also facilitates psychomotor performance during heavy exercise.

TL;DR: Schizophrenia patients demonstrate diminished motor- and non-motor-related anticipatory processing, which may have wide-ranging adverse functional consequences, and generally lower CNV and SPN across pleasant, neutral, and unpleasant picture conditions.

TL;DR: An alternative perspective on the psychophysiology of BII phobia and vasovagal fainting is offered by focusing on hypocapnia that leads to cerebral blood flow reductions, a perspective supported by research on neurocardiogenic and orthostatically-induced syncope.

TL;DR: Examination of event-related brain potentials to examine whether anger styles uniquely predict attentional bias to negative stimuli during an emotion-word Stroop task indicated that aggressive individuals exert more effort to override attention to negative information.

TL;DR: It is cautiously concluded that the classification of alexithymics on the basis of both the affective and cognitive components, rather than on the based of the cognitive component only, might provide more consistent research results, and thus lead to a better understanding of emotional physiological responses in a lexithymic subjects.

TL;DR: Although language abnormalities are more pronounced in patients with positive thought disorder, they manifest themselves in all patients when increased demands are placed on the comprehension system, and further investigation of language dysfunction may also provide insights into other aspects of psychotic thought.

TL;DR: Semantic processing and verbal fluency studies did not provide substantive evidence of specific left frontal lobe deficits, and evidence that emotional information may differentially impact brain functioning relative to neutral information in depression suggests that examination of verbalfluency for emotional Information may contribute to the elucidation of executive functioning processes associated with the dorsolateral prefrontal cortex in depression.

TL;DR: Monitoring electrodermal and cardiac activities of healthy participants to event outcomes during a task on a real EGM demonstrated that it is possible to reliably capture the profile of physiological changes as they occurred in real time to the many different win and loss events during electronic gambling.

TL;DR: The results suggest that cardiac assessment can be a useful addition to self-report measures for determining flight task mental workload and risk for performance decrements.

TL;DR: EEG (Electroencephalography) resting state was studied by means of group blind source separation (gBSS), employing a test-retest strategy in two large-sample normative databases, resulting in a new tool that may serve as an adjunct to diagnosis and assessment of abnormal brain functioning and aid in research on normal resting state networks.

TL;DR: It is shown that letter-speech sound integration does not resemble the processes involved in the integration of natural audiovisual objects such as audiovi-sensory visual and auditory cortices in audiovISual speech integration.

TL;DR: The interaction between African-American ethnicity and Type D personality was predictive of both low and high frequency HRV during stressful imagery experiences during three guided imagery experiences in a non-medical sample.

TL;DR: In this article, the authors examined physiological and subjective measures of negative affect when viewing static IAPS images, static computer generated images and moving videos of computer-generated images of feared stimuli and other negative stimuli which were not specifically feared.
