Brief Report: Attenuated Emotional Suppression of the Attentional Blink in Autism Spectrum Disorder: Another Non-Social Abnormality?

Twenty-five individuals with Autism Spectrum Disorder and 25 typically developed individuals participated in an Attentional Blink paradigm to determine whether emotional words would capture attention similarly in the two groups. Whilst the emotionality of words facilitated attention in typical comparison participants, this effect was attenuated in the ASD group. The magnitude of the emotional modulation of attention in ASD also correlated significantly with participants’ VIQ, which was not observed for the comparison group. Together these observations replicate and extend the findings of Corden et al. (J Autism Develop Disord 38:1072–1080, 2008) and implicate abnormalities in emotional processes outside the broader context of social cognition in ASD. We discuss our findings in relation to possible abnormalities in amygdala function that may underlie the disorder

Introduction revisiting the Argentine crisis a decade on: changes and continuities

This introductory chapter to the book "Argentina Since the 2001 Crisis Recovering the Past, Reclaiming the Future" analyses crisis and its associated responses and subsequent recovery in the context of Argentina’s multiple implosion of 2001-02 whilst also assessing its legacies for the country’s social, cultural, economic and political realms during the last decade. It recognises that "crisis" is a term that is much used in the post-Lehman Brothers world and that the subsequent responses and associated recoveries (or lack of) have been the subject of a cascade of academic, government, media, and think-tank investigation ever since. The chapter instead seeks to understand the nature of how crisis and its impacts should be investigated and interrogated, by rejecting false dichotomies of ‘old’ and ‘new’ and synthesising understanding to form an analysis that draws both elements of continuity and elements of change. Secondly, it argues that crisis manifests itself in a number of realms, and that heuristic devices employed to investigate them must subsequently also be drawn from across a range of disciplinary perspectives. Thirdly, it examines how the 2001-02 crisis in Argentina led to a series of responses that both rejected the neoliberal model yet also recovered elements of it. Finally it outlines the structure of the rest of the book, briefly summarising the chapters in turn

Modo borderline e mundo do trabalho: um ensaio sobre implicações e perspectivas atuais

Resumo Partindo do pressuposto de que o modo border line parece constituir uma nova "normalidade" atualmente, este artigo busca discutir a sociedade contemporânea em seus modos de vida e o impacto sobre o mundo do trabalho. A busca constante pelo sucesso e pela realização profissional atravessa, consequentemente, as relações de trabalho, que constituem o sujeito. Não há tempo para vazios! É preciso produzir. Considera-se para a discussão o que chamamos de "modo borderline", pensado a partir de sua dimensão fenomenológica e não estrutural, portanto, não a partir do paradigma da psicopatologia individual, mas como sintoma da cultura, em uma sociedade marcada pela im pulsividade, fragilidade dos laços sociais e pela chamada "cultura do narcisismo". Através de uma abordagem psicanalítica e com breve descrição da evolução dos modos de trabalho e produção ao longo dos anos, propõe-se uma discussão a respeito dessas novas configurações de vida implicadas no mundo do trabalho, pensando, sobretudo, em como se dá essa relação na contemporaneidade, em pleno capitalismo flexível

Altered oscillatory brain dynamics after repeated traumatic stress

Kolassa I-T, Wienbruch C, Neuner F, et al. Altered oscillatory brain dynamics after repeated traumatic stress. BMC Psychiatry. 2007;7(1): 56.BACKGROUND: Repeated traumatic experiences, e.g. torture and war, lead to functional and structural cerebral changes, which should be detectable in cortical dynamics. Abnormal slow waves produced within circumscribed brain regions during a resting state have been associated with lesioned neural circuitry in neurological disorders and more recently also in mental illness. METHODS: Using magnetoencephalographic (MEG-based) source imaging, we mapped abnormal distributions of generators of slow waves in 97 survivors of torture and war with posttraumatic stress disorder (PTSD) in comparison to 97 controls. RESULTS: PTSD patients showed elevated production of focally generated slow waves (1-4 Hz), particularly in left temporal brain regions, with peak activities in the region of the insula. Furthermore, differential slow wave activity in right frontal areas was found in PTSD patients compared to controls. CONCLUSION: The insula, as a site of multimodal convergence, could play a key role in understanding the pathophysiology of PTSD, possibly accounting for what has been called posttraumatic alexithymia, i.e., reduced ability to identify, express and regulate emotional responses to reminders of traumatic events. Differences in activity in right frontal areas may indicate a dysfunctional PFC, which may lead to diminished extinction of conditioned fear and reduced inhibition of the amygdala

Urban Biodiversity, City-Dwellers and Conservation: How Does an Outdoor Activity Day Affect the Human-Nature Relationship?

Urban conservation education programs aim to increase knowledge and awareness towards biodiversity and to change attitudes and behaviour towards the environment. However, to date, few urban conservation education studies have evaluated to what extent these programs have managed to achieve their goals. In this study, we experimentally explored the influence of an urban conservation activity day on individual knowledge, awareness and actions towards biodiversity, in both the short and longer term

Context-Dependent Encoding of Fear and Extinction Memories in a Large-Scale Network Model of the Basal Amygdala

The basal nucleus of the amygdala (BA) is involved in the formation of context-dependent conditioned fear and extinction memories. To understand the underlying neural mechanisms we developed a large-scale neuron network model of the BA, composed of excitatory and inhibitory leaky-integrate-and-fire neurons. Excitatory BA neurons received conditioned stimulus (CS)-related input from the adjacent lateral nucleus (LA) and contextual input from the hippocampus or medial prefrontal cortex (mPFC). We implemented a plasticity mechanism according to which CS and contextual synapses were potentiated if CS and contextual inputs temporally coincided on the afferents of the excitatory neurons. Our simulations revealed a differential recruitment of two distinct subpopulations of BA neurons during conditioning and extinction, mimicking the activation of experimentally observed cell populations. We propose that these two subgroups encode contextual specificity of fear and extinction memories, respectively. Mutual competition between them, mediated by feedback inhibition and driven by contextual inputs, regulates the activity in the central amygdala (CEA) thereby controlling amygdala output and fear behavior. The model makes multiple testable predictions that may advance our understanding of fear and extinction memories
