Full text linkIntroduction: The heart-brain connection represents an interesting innovative framework for investigating the complex and reciprocal influences between the cardiovascular system and brain activity in emotion research. The present study aimed at investigating the correlation between heart rate and connectivity within brain regions relevant for interoception and emotional regulation (i.e., the Ventral Attention Network) during ecological stimulation with validated emotional video-clips. Methods: To this end two groups of 25 healthy female students were enrolled (mean age 22.62 ± 1.87SD), after a selection from 422 students, based on questionnaires measuring emotion dysregulation. Both the High Dysregulation (HD) and Low Dysregulation (LD) groups watched 18 validated video-clips divided in 6 different emotional categories (Erotic, Scenery, Neutral, Sadness, Compassion and Fear) while EEG from 64 electrodes and heart rate (HR) were recorded. Focusing on alpha and gamma EEG rhythms, the connectivity within the VAN network and between VAN and other five relevant networks (DAN, DMN, LN, SMN, VN) was computed and then correlated with the heart rate. Results: Results showed a different pattern of HR-Network-connectivity correlation in the two groups. EEG Gamma band evidenced several effects only in the HD group with significant positive HR-Network-connectivity correlations for most networks during the Sadness and Neutral movies and to a less extent for Scenery clips (all rs ≥ 0.29, p < 0.05). Discussion: The consistent correlation in HD during Sadness clips points to the relevance of this emotion as a synchronizing agent coordinating cardiovascular and central cortical responses. Unlike the HD, the LD group showed, in the alpha EEG band only, a negative HR-Brain-connectivity correlation in three networks during the Erotic clips, a result that highlights a normal increased attention (bradycardic response) towards relevant biological appetitive cues, while the HD group had an opposite pattern with positive HR- Brain correlation to Erotic in the gamma band that could be explained by greater sexual issues and embarrassment to these stimuli in HD individuals
Brain asymmetry in resting state and during linguistic tasks in major depression vs. dysthymia: an EEG alpha study
Full text linkIntroduction: Mood disorders are relatively heterogeneous and there is limited research on the psychobiological distinctive features of Dysthymia with respect to Major Depression. In line with past studies, they are expected to exhibit inverted brain asymmetries. Objectives: We aimed to investigate altered asymmetry of EEG Alpha band in MDD, Dysthymia patients and healthy controls during resting state and two linguistic tasks: phonological and semantic. We hypothesized, in patients with Dysthymia compared with MDD, a greater extent of inverted hemispheric asymmetry due to the structured lifetime nature of their disorder. Methods: We recorded EEG Alpha activity as an index of cortical inhibition, in 20 MDD patients, 20 Dysthymic patients and 20 healthy controls (all groups matched) during the three tasks. Electrodes were clustered in four main regions, two anterior (left and right) and two posterior (left and right). Statistics were carried out by means of ANOVA. Results: In frontal sites, no Alpha asymmetry was found in the groups, but Dysthymic patients had an overall greater Alpha activity across all tasks. The same effect was found in posterior regions, but, in addition, greater Alpha on the left was found during resting state for all groups. Dysthymic patients only maintained this altered asymmetry also during the linguistic tasks. Conclusions: Our findings highlight the role of linguistic tasks in assessing deficits in hemispheric integration in mood disorders. Dysthymic patients, who suffer from a lifetime disorder, exhibited an overall greater cortical inhibition especially on the left posterior sites, which was not counterbalanced by left lateralization-inducing tasks
The experience of leaving a valuable object: An investigation of emotional processes related to Hoarding disorder features
Full text link: One of the core features of hoarding is a significant resistance to discarding objects, which is fueled by dysfunctional beliefs and unwarranted negative emotions that hoarders tend to feel when disposing of their possessions. To our knowledge, longitudinal studies investigating the psychological effects that people who hoard experience after separating from their valuable possessions have yet to be conducted. Our study's principal aim was to explore psychological processes that individuals with high hoarding features (n = 53; 49.1%) and individuals with low hoarding features (n = 55; 50.9%) experienced when they had to separate from a valuable possession. To do this, we evaluated participants' thoughts and feelings at several time points after they had to leave a valuable object at the University laboratory (evaluations were specifically conducted at baseline, during the week, and at the end of the week). To investigate hoarding and anxiety, as well as depressive, obsessive-compulsive, and emotional processes-related features, a mixed-method approach was employed involving self-report questionnaires, ad hoc surveys, and a daily self-monitoring schedule. Our findings showed that compared to participants with low hoarding features, participants with high hoarding traits: 1) scored higher for anxiety sensitivity, distress tolerance, and emotional dysregulation; 2) reported having more negative emotions when leaving their object; 3) had more intrusive object-related beliefs; and 4) experienced a higher frequency of negative emotions as well as a higher level of distress during the week. Both groups experienced more negative emotions in the first part of the week, which decreased as the time at which participants could receive their object back drew closer. Finally, dysfunctional beliefs about leaving a personal object (Saving Cognitions Inventory), sensitivity to anxiety (Anxiety Sensitivity Index-3), and distress tolerance (Distress Tolerance Scale) contributed to the level of discomfort that participants with higher hoarding scores reported when they had to leave their possession. These results highlight the relevance of emotional processes in the hoarding disorder framework as well as underscore the importance of assessing and treating them in clinical settings
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
