A Pilot Study of Neurofeedback for Chronic PTSD.

Abstract: EEG Biofeedback (also known as neurofeedback) has been in use as a clinical intervention for well over 30 years; however, it has made very little impact on clinical care. One reason for this has been the difficulty in designing research to measure clinical change in the real world. While substantial evidence exists for its efficacy in treating attention deficit/hyperactivity disorder, relatively little evidence exists for its utility in other disorders including posttraumatic stress disorder (PTSD). The current study represents a "proof-of-concept" pilot for the use of neurofeedback with multiply-traumatized individuals with treatment-resistant PTSD. Participants completed 40 sessions of neurofeedback training two times per week with sensors randomly assigned (by the study coordinator, who was not blind to condition) to sensor placements of either T4-P4 or T3-T4. We found that neurofeedback significantly reduced PTSD symptoms (Davidson Trauma Scale scores averaged 69.14 at baseline to 49.26 at termination), and preceded gains in affect regulation (Inventory of Altered Self-Capacities-Affect Dysregulation scores averaged 23.63 at baseline to 17.20 at termination). We discuss a roadmap for future research.

The social biology of domiciliary cockroaches: colony structure, kin recognition and collective decisions

Abstract: A substantial body of research on eusocial insects seen in the last decades has gone hand-in-hand with the development of social evolution theory. In contrast, little attention has been given to the non-eusocial insect species that nevertheless exhibit a rich spectrum of social behaviours, thus effectively skewing our vision of insect sociality. Recent studies on the behaviour, ecology and genetic of “gregarious” cockroaches (Blattodea) have revealed a diversity of social structures and group dynamics unique among insects, providing an important comparative model for the broader understanding of insect social evolution. Here, we present an overview of the social biology of the domiciliary cockroaches (ca. 25 species adapted to human habitats) based on research on two model species, Blattella germanica and Periplaneta americana. We discuss the evolution of these domiciliary cockroaches, considering them in the context of “social herds” within the insect sociality framework.

Mental Health Disparities Across Education and Sex: A Prospective Analysis Examining How They Persist Over the Life Course

Abstract: Objectives. Higher levels of psychopathology among people with lower socioeconomic status and among women persist as cohorts age. In this analysis, we examine whether the persistence of these disparities as a cohort ages results from (a) a single set of people within a disadvantaged group who have chronic psychopathology or (b) continually changing sets of people within a disadvantaged group who have psychopathology of short duration. Methods. Data for this analysis come from the Epidemiologic Catchment Area Study, which includes two psychological assessments (depressive syndrome and psychological distress) in a population sample of adults in Baltimore, Maryland, collected 13 years apart. Results and Discussion. Results indicate that the persistence of disparities across education resulted primarily from one single set of respondents with chronic psychopathology over the 13 years of the survey, while the persistence of disparities across sex involved new sets of women as the cohort aged. We discuss implications of these results for theory and policy.
