Abstract Background Migraine is a common and disabling primary headache, which is associated with a wide range of psychiatric comorbidities. However, the mechanisms of emotion processing in migraine are not fully understood yet. The present study aimed to investigate the neural network during neutral, positive, and negative emotional stimuli in the migraine patients. Methods A total of 24 migraine patients and 24 age- and sex-matching healthy controls were enrolled in this study. Neuromagnetic brain activity was recorded using a whole-head magnetoencephalography (MEG) system upon exposure to human facial expression stimuli. MEG data were analyzed in multi-frequency ranges from 1 to 100 Hz. Results The migraine patients exhibited a significant enhancement in the effective connectivity from the prefrontal lobe to the temporal cortex during the negative emotional stimuli in the gamma frequency (30–90 Hz). Graph theory analysis revealed that the migraine patients had an increased degree and clustering coefficient of connectivity in the delta frequency range (1–4 Hz) upon exposure to positive emotional stimuli and an increased degree of connectivity in the delta frequency range (1–4 Hz) upon exposure to negative emotional stimuli. Clinical correlation analysis showed that the history, attack frequency, duration, and neuropsychological scales of the migraine patients had a negative correlation with the network parameters in certain frequency ranges. Conclusions The results suggested that the individuals with migraine showed deviant effective connectivity in viewing the human facial expressions in multi-frequencies. The prefrontal-temporal pathway might be related to the altered negative emotional modulation in migraine. These findings suggested that migraine might be characterized by more universal altered cerebral processing of negative stimuli. Since the significant result in this study was frequency-specific, more independent replicative studies are needed to confirm these results, and to elucidate the neurocircuitry underlying the association between migraine and emotional conditions.

AbstractEmotion enhances episodic memory, an effect thought to be an adaptation to prioritise the memories that best serve evolutionary fitness. But viewing this effect largely in terms of prioritising what to encode or consolidate neglects broader rational considerations about what sorts of associations should be formed at encoding, and which should be retrieved later. Although neurobiological investigations have provided many mechanistic clues about how emotional arousal modulates item memory, these effects have not been wholly integrated with the cognitive and computational neuroscience of memory more generally.Here we apply the Context Maintenance and Retrieval Model (CMR, Polyn, Norman & Kahana, 2009) to this problem by extending it to describe the way people may represent and process emotional information. A number of ways to operationalise the effect of emotion were tested. The winning emotional CMR (eCMR) model reconceptualises emotional memory effects as arising from the modulation of a process by which memories become bound to ever-changing temporal and emotional contexts. eCMR provides a good qualitative fit for the emotional list-composition effect and the emotional oddball effect, illuminating how these effects are jointly determined by the interplay of encoding and retrieval processes. eCMR explains the increased advantage of emotional memories in delayed memory tests through the limited ability of retrieval to reinstate the temporal context of encoding.By leveraging the rich tradition of temporal context models, eCMR helps integrate existing effects of emotion and provides a powerful tool to test mechanisms by which emotion affects memory in a broad range of paradigms.

Mission critical domains (MCDs), such as fire fighting, military combat, etc., experience periods of nonequilibrium. This typically occurs when extended periods of low grade activity are punctuated by intense, high stakes actions unfolding at high velocities (e.g., fighting a fire, engaging in combat, etc.). These periods of nonequilibrium are typically characterized by volatility, uncertainty, complexity and ambiguity. Human agents operating under these conditions experience a variety of reactions, such as emotional modulation of cognition, recognition primed decision making, among others. To study this phenomenon a construct named High Velocity Human Factors (HVHF) is defined and described. On the practical side, the HVHF framework will be used to analyze demands placed on personnel operating in MCDs and inform the design of systems and solutions.

This chapter considers the neurobiology of aggression both the neural systems mediating this behavior as well as how these systems can become perturbed such that the aggression is maladaptive to the individual. A distinction will be drawn between planned, goal directed instrumental aggression and threat/ frustration based reactive aggression. Instrumental aggression implicates the neural systems involved in instrumental motor behavior generally as well as emotional learning and decision making systems that allow the selection of one action over another. Conditions decreasing the responsiveness of neural systems allowing good decision making (amygdala, striatum, ventromedial prefrontal cortex) are associated with an increased risk for maladaptive instrumental aggression. Reactive aggression implicates sub cortical systems involved in the basic response to threat as well as cortical systems involved in emotional modulation and the response to norm violations.
