TL;DR: A brief, preliminary attempt is made to frame a scientific debate about how functional responses at gamma frequencies in electrophysiological recordings (EEG, MEG, ECoG, and LFP) should be classified and interpreted.

TL;DR: The results suggest that afferent feedback from visceral activity may contribute to inferences about the affective state of others.

TL;DR: The results suggest that long-range synchrony of gamma oscillations is disturbed in schizophrenia and that this deficit is related to clinical symptoms such as auditory hallucinations.

TL;DR: It was found that N1, P2, P3 and late positive potential (LPP) component amplitudes were inversely related to task-difficulty, suggesting that a variant of the oddball paradigm is capable of providing a reliable index of mental workload.

TL;DR: Results indicate that an fMRI experiment may elicit subjective and neuroendocrine stress reactions that can influence functional activation patterns and lead to impaired data quality and premature termination of scans.

TL;DR: These first reported objective measures for cognitive-emotional behavior obtained in relation to delta-beta coherence provide additional support for the hypothesis that this EEG parameter may reflect emotion regulation processes and supports suggestions that δ-β coherence may be a useful tool in the experimental study of affect and psychopathology.

TL;DR: Findings here demonstrate significantly increased resting connectivity internal-state networks in the TBI sample during the first 6 months following recovery.

TL;DR: Overall, the results suggest that IU is associated with attenuated aversive responding to uncertain threat, and several potential explanations for these findings are discussed.

TL;DR: The analysis showed that dynamic expressions were rated as more intense than static ones, suggesting that the dynamic property facilitates processing of facial expressions of emotions.

TL;DR: In this article, EEG signatures were investigated for perception and imagery of two different natural musical phrases, and responses were compared between tasks and between stimuli for all tasks and stimuli, but differences are shown in the power of this response As expected, imagery resulted in a significantly stronger alpha activation than perception.

TL;DR: The results suggest that deviant attentional processing in children with ADHD is only partly related to ANT-specific effects, and are compatible with the model of a suboptimal energetic state regulation in ADHD.

TL;DR: Results suggest that activation of the anterior PFC and 5-HT system may be responsible for the improvement of negative mood and EEG signal changes observed during FA on Tanden breathing.

TL;DR: The psychological presence of an attachment figure attenuated hypothalamus activation during episodes of social exclusion, thereby providing insight into the neural mechanisms by which attachment relationships may help in coping with social stress.

TL;DR: The motivation- and affect-related psychophysiological responses to gaze direction are most discriminative in the presence of another person, regardless of whether the face/gaze is actively monitored or not.

TL;DR: The interventions were associated with stronger prefrontal alpha activity in the upper alpha band than the control condition (no intervention), possibly indicating a state of heightened internal awareness, which might have a beneficial impact on creativity.

TL;DR: Female participants showed a stronger increase in theta oscillations during processing of landmarks as navigational aids compared to a baseline condition than men, which might indicate a stronger sensorimotor integration in females than in males.

TL;DR: Previous work that suggests the conflict SP is sensitive to conflict adaptation in healthy individuals, but is decreased in individuals across the range of TBI severity is replicated and extended.

TL;DR: Although arousal differences may account for some differences in physiological responding this shows that not all emotional material that is decoded similarly leads to the same psychophysiological output.

TL;DR: Results suggest a divergence between self-report and psychophysiological measures of emotion in NSSI.

TL;DR: The results indicate that SR faces involve more configural/holistic processing OR faces, and that face inversion effect was observed for all ethnic groups on N170 amplitudes, but was more evident for Caucasian faces.

TL;DR: Two studies suggest that the level of immersion of a fixed base simulator is great enough to elicit presence, and achieve both relative and absolute validity for certain physiological parameters.

TL;DR: The effect of multiple repetitions on the processing of names and faces varying in terms of pre-experimental familiarity is investigated to suggest that the process of learning faces is more effective than learning names, possibly because faces carry more semantic information.

TL;DR: During the short post-awakening period, an exception exists to the generally pertaining association between higher levels of cortisol and poorer cognitive performance, and the pattern of results across different cognitive tests suggests an association between cortisol and those domains of cognitive functioning which depend crucially on the integrity of the hippocampus and pre-frontal cortex.

TL;DR: Results show that in an anxiogenic situation, delta-beta correlation increases in a network of cortical areas which includes the orbitofrontal and the anterior cingulate cortices as its main node and is accompanied by an increase of delta power and connectivity in the same cortical regions.

TL;DR: Results indicated that blood pressure recovery was hampered by the negative affect manipulation and by rumination, however, the positive affect manipulation did not facilitateBlood pressure recovery.

TL;DR: This study used a flanker task motivated by potential reward and potential punishment on different trials and also examined the N2 and P2 to the imperative stimulus, the response Pe, and the FRN and P3 to the outcome feedback to assess the impact of motivation valence on other stages of information processing in this choice reaction time task.

TL;DR: The findings support a negative relation of concussive injury to neuroelectric indices of brain health and cognition in the presence of normal clinical findings and suggest that event-related brain potentials are especially well-suited for identifying aspects of cognition that remain dysfunctional for an extended period of time.

TL;DR: An overview of the current applications of conventional EEG and qEEG to the study and clinical evaluation of persons with mTBI is offered to serve more immediately the needs of clinicians less familiar with these types of clinical electrophysiologic assessments.

TL;DR: The stimulus- and response-locked data lead to the conclusion that the parietal region is primarily involved in response selection in the Stroop task, and that the lateral frontal regions may participate in response monitoring and conflict adaption.

TL;DR: 24-hour SC recording outside the laboratory is feasible, but some measures need to be corrected for the influence of confounding variables.
