Neuroscientific research on empathy has made much progress recently. How far can we get and how should we do it? Two different routes have been suggested by Dziobek and Jacobs in their commentaries. The first is becoming ecologically more valid by using real-life settings as stimuli. The second is becoming more quantitative by specifying a neurocognitive model, allowing more precise quantitative predictions. Although neither approaches are mutually exclusive, I suggest that these two routes are in a certain tension to each other. I suggest an additional third, more indirect way, namely studying modulating factors of empathy like emotion regulation which have until now been largely neglected in empathy research.

Abstract This article focuses on a mathematical description of the emotional phenomenon. The key concept is to consider emotions as an energy, and to rely on the analogy with the electromagnetic waves. Our aim is to provide a mathematical approach to characterize the emergence of emotional fluxes in the human psyche. This goes beyond classical pscychological approaches. In this setting, specific emotions correspond to specific frequencies and our psychic state results from the summation of different characteristic frequencies. Our general model of psychic state is a dynamical system whose evolution results from interactions between external inputs and internal reactions. The model provides both qualitative (frequencies) and quantitative (intensity) components. It aims to be applied to real life situations (in particular in work environments) and we provide a typical example which naturally leads to a problem of control.

AbstractMost Pb and Cd neurotoxicity studies investigate exposure to either of the toxic metals alone, while data on co-exposure are scarce. The aim of our study was to fill that gap by investigating acute combined effects of Pb and Cd on redox and essential metal status in the brain of Wistar rats. Animals were randomised in four groups of six to eight rats, which received 15 or 30 mg/kg of Cd, 150 mg/kg of Pb, or 150 mg/kg of Pb + 15 mg/kg of Cd by gavage. The fifth, control, group received distilled water only. Co-treatment with Pb and Cd induced significant increase in malondialdehyde (MDA) and thiobarbituric acid-reactive substances (TBARS) compared to control and groups receiving either metal alone. This is of special importance, as MDA presence in the brain has been implicated in many neurodegenerative disorders. The groups did not significantly differ in Zn, Cu, Mn, and Fe brain levels. Our findings highlight the importance of metal mixture studies. Neurotoxicity assessments of single chemicals do not provide a real insight into exposure to mixtures in real life. Further research should look into interactions between these metals to reveal complex molecular mechanisms of their neurotoxicity.

The purpose of this study was to investigate differences, between swimmer-lifeguards and swimmer-non-lifeguards, in trait and state anxiety and emotion regulation techniques in a real-life precompetitive situation with a secondary focus on gender differences. The Emotion Regulation Questionnaire, Sport Anxiety Scale – 2 and the Mental Readiness Form – 3 were distributed to 100 participants at university swimming competitions in the United Kingdom. Swimmer-lifeguards displayed significantly lower cognitive (p=.03) and somatic state (p=.05) anxiety and cognitive trait anxiety (p=.02) than swimmer-non-lifeguards. Males reported significantly lower levels of cognitive and somatic trait anxiety (ppp=.01); no other effects were observed. These results support previous research regarding lifeguard characteristics, however the nature of these qualities and how they originate require further exploration.

From decision making to perception to language, predicting what is coming next is crucial. It is also challenging in stochastic, changing, and structured environments; yet the brain makes accurate predictions in many situations. What computational architecture could enable this feat? Bayesian inference makes optimal predictions but is prohibitively difficult to compute. Here, we show that a specific recurrent neural network architecture enables simple and accurate solutions in several environments. To this end, a set of three mechanisms suffices: gating, lateral connections, and recurrent weight tuning. Like the human brain, such networks develop internal representations of their changing environment (including estimates of the environment's latent variables and the precision of these estimates), leverage multiple levels of latent structure, and adapt their effective learning rate to changes without changing their connection weights. Being ubiquitous in the brain, gated recurrence could therefore serve as a generic building block to predict in real-life environments.

AbstractMost experiments using EEG recordings take place in highly isolated and restricted environments, limiting their applicability to real-life scenarios. New technologies for mobile EEG are changing this by allowing EEG recording to take place outside of the laboratory. However, before results from experiments performed outside the laboratory can be fully understood, the effects of ecological stimuli on brain activity during cognitive tasks must be examined. In this experiment, participants performed an auditory oddball task while also listening to concurrent background noises of silence, white noise and outdoor ecological sounds, as well as a condition in which the tones themselves were at a low volume. We found a significantly increased N1 and decreased P2 when participants performed the task with outdoor sounds and white noise in the background, with the largest differences in the outdoor sound condition. This modulation in the N1 and P2 replicates what we have previously found outside while people ride bicycles (Scanlon et al., 2017b). No behavioural differences were found in response to the target tones. We interpret these modulations in early ERPs as indicative of sensory filtering of background sounds, and that ecologically valid sounds require more filtering than synthetic sounds. Our results reveal that much of what we understand about the brain will need to be updated as we step outside the lab.

AbstractThe neural basis of emotional processing has been largely investigated in constrained spatial environments such as stationary EEGs or fMRI scanners using highly artificial stimuli like standardized pictures depicting emotional scenes. Typically, such standardized experiments have low ecological validity and it remains unclear whether their results reflect neuronal processing in real-life affective situations at all. Critically, emotional situations do not only encompass the perception of emotions, but also behavioral components associated with them. In this study, we aimed to investigate real-life emotions by recording couples in their homes using mobile EEG technology during embracing, kissing and emotional speech. We focused on asymmetries in affective processing as emotions have been demonstrated to be strongly lateralized in the brain. We found higher alpha and beta power asymmetry during kissing and embracing on frontal electrodes during emotional kisses and speech compared to a neutral control condition indicative of stronger left-hemispheric activation. In contrast, we found lower alpha power asymmetry at parieto-occipital electrode sites in the emotional compared to the neutral condition indicative of stronger right-hemispheric activation. Our findings are in line with models of emotional lateralization that postulate a valence-specific processing over frontal cortices and right-hemispheric dominance in emotional processing in parieto-occipital regions. Overall, we could thus support theories of emotional asymmetries which suggest that affective processing is not uniformly lateralized across the brain using a highly ecologically valid paradigm.

ABSTRACTBackgroundImpaired brain processing of alcohol-related rewards has been suggested to play a central role in alcohol use disorder. Yet, evidence remains inconsistent, and mainly originates from studies in which participants passively observe alcohol cues or taste alcohol. Here we designed a protocol in which beer consumption was predicted by incentive cues and contingent on instrumental action, closer to real life situations. We predicted that anticipating and receiving beer (compared with water) would elicit activity in the brain reward network, and that this activity would correlate with drinking level across participants.MethodsThe sample consisted of 150 beer-drinking males, aged 18-25 years. Three groups were defined based on AUDIT scores: light drinkers (n=40), at-risk drinkers (n=63), and dependent drinkers (n=47). fMRI measures were obtained while participants engaged in the Beer Incentive Delay task involving beer- and water-predicting cues, followed by real sips of beer or water.ResultsDuring anticipation, outcome notification and delivery of beer compared with water, higher activity was found in a reward-related brain network including the medial prefrontal cortex, orbitofrontal cortex and amygdala. Yet, no activity was observed in the striatum, and no differences were found between the groups.ConclusionsOur results reveal that anticipating, obtaining and tasting beer activates parts of the brain reward network, but that these brain responses do not differentiate between different drinking levels. We speculate that other factors, such as cognitive control or sensitivity to social context, may be more discriminant predictors of drinking behaviour in young adults.

The actual intensive and extensive growth of international neuropsychology (both theoretical and applied) testified in the paper, is due to the abilities of contemporary professional neuropsychologists to meet different purposes beyond understanding of brain-behavior relationships. It makes contemporary neuropsychology an important part of the psychology of health, instead to be an aspect of the biology of health. The value and the history of Lurian syndrome analysis are presented. The Lurian syndrome analysis (a qualitative (structural) analysis of the symptom under study), not only permits an understanding of why the subject was poor at or unable to perform a given task. Such an approach also allows us to see what other tasks, with similar cognitive demands (structure), could present difficulties for this individual (child or adult) as well as to predict the types of tasks accessible for the patient and the types of cueing efficient for him/her. The last is possible in conditions of dialogue interaction with the patient in the process of neuropsychological assessment. Lurian approach is oriented on the process of test fulfilment (the means by which the performer achieves or better the result as well as the level of necessary help or stimulation), more than on the test result — the level of performance on a task (accuracy, time, number of mistakes and so on) with reference to some expected (normative) level of performance. The evolution of neuropsychology coincides with the universal tendency to replace a static neuropsychology, relating the individual’s behavior to fixed cerebral lesions, by a dynamic neuropsychology, which analyzes the dynamics of brain-behavior interaction in different social conditions and at different steps of ontogenic evolution. The author gives own model of neuropsychology evolution, including three overlapping and coexisting phases different in the main emphasis for neuropsychologists. In the first phase, the accent was on the brain and its relationship to different behaviors. In the second phase of neuropsychology evolution the structure of mental activity and neuropsychological interpretation of human cognition have been the focus of attention and afterwards their localization in the brain. The third and actually dominant phase of evolution in neuropsychology focuses on the interrelationship between a patient and his or her environment and integrates neuropsychological and real life data. This phase gave birth to social — historical or cultural — historical neuropsychology. One of the important consequences of cultural — historical approach in neuropsychology was the introduction of cultural adjustments in neuropsychological diagnostic tests, both verbal and nonverbal. Qualitative and quantitative integration of Lurian procedures are discussed. Underlined are differences in concepts neuropsychology and neurosciences, as well as the role of cultural-historical approach in contemporary neuropsychological assessment, rehabilitation and remediation. Three main trends can be seen in the evolution of neuropsychology after Luria: 1. Extensive further expansion of research and practice, that is, embracing numerous new domains and nosological patient groups; 2. Combination of qualitative and quantitative approaches; 3. Social and personality-based orientation. Luria’s creative and comprehensive approach stimulates the further evolution of neuropsychology in Russia and throughout the world.
