Is Tolerance Political? An Interview with Denis Lacorne
No full textcontribution à un site webDenis Lacorne is the author of "The Limits of Tolerance. Enlightenment Values and Religious Fanaticism" (Columbia University Press, 2019), the English translation of "Les limites de la tolérance" (Gallimard, awarded the Prix Montyon by the Académie Française). In his book, which is intellectually very inspiring because of the many questions it addresses and raises, Denis Lacorne traces the emergence of the notion of tolerance from its early thinkers to the Age of Enlightenment and finally questions the notion and its various understandings through more recent events in France and the United States.

Timing of impulses from the central amygdala and bed nucleus of the stria terminalis to the brainstem
No full textThe amygdala and bed nucleus of the stria terminalis (BNST) are thought to subserve distinct functions with the former mediating rapid fear responses to discrete sensory cues and the latter longer “anxiety-like” states in response to diffuse environmental contingencies. Yet, these structures are reciprocally connected and their projection sites overlap extensively. To shed light on the significance of BNST-amygdala connections, we compared the antidromic response latencies of BNST and central amygdala (CE) neurons to brainstem stimulation. Whereas the frequency distribution of latencies was unimodal in BNST neurons (~10 ms mode), that of CE neurons was bimodal (~10 and ~30 ms modes). However, after stria terminalis (ST) lesions, only short-latency antidromic responses were observed, suggesting that CE axons with long conduction times course through the ST. Compared to the direct route, the ST greatly lengthens the path of CE axons to the brainstem, an apparently disadvantageous arrangement. Since BNST and CE share major excitatory basolateral amygdala (BL) inputs, lengthening the path of CE axons might allow synchronization of BNST and CE impulses to brainstem when activated by BL. To test this, we applied electrical BL stimuli and compared orthodromic response latencies in CE and BNST neurons. The latency difference between CE and BNST neurons to BL stimuli approximated that seen between the antidromic responses of BNST cells and CE neurons with long-conduction times. These results point to a hitherto unsuspected level of temporal coordination between the inputs and outputs of CE and BNST neurons, supporting the idea of shared functions.The original publication is available at: http://jn.physiology.org/cgi/content/full/100/6/342
Escrínio, Andradina de Oliveira e sociedade(s): entrelaços de um legado feminista
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2015.Esta tese de doutorado teve por objetivo analisar a trajetória histórica do periódico feminino gaúcho Escrínio, publicado, inicialmente, na cidade de Bagé, (RS), em 2 de janeiro de 1898 e, posteriormente, tendo sido editado nas cidades Sul-rio-grandenses: Rio Grande, Santa Marie e Porto Alegre, esta última onde encerrou suas publicações em 25 de junho de 1910. Editado pela escritora Andradina América de Andrada e Oliveira (1864-1935), o periódico mostrou-se como substrato na consolidação de uma rede de comunicação nas diversas relações estabelecidas entre as mulheres intelectuais no Brasil e fora do país. Nesse contexto, tomou-se não só o periódico como fonte primária de pesquisa, como também os jornais editados em espaços geopolíticos distintos, buscando-se um ponto de contato entre feministas portuguesas e gaúchas. Concomitantemente, ampliou-se o corpus de estudo, considerando-se inserção de Andradina no universo das letras, no exame de algumas suas obras literárias as quais serviram de tribuna para seu um discurso crítico, nos mínimos detalhes da vida cotidiana, ocupando uma relevância no processo de discussões sobre o regime patriarcal, mecanismo dominante da época. Sendo assim, o estudo propiciou o vínculo do periódico e sua redatora, com o pensamento evolutivo do feminismo, promovendo uma reflexão entre gênero, subjetividade e relações de poder, em tempos difíceis para a produção intelectual das mulheres oitocentistas.Abstract : This doctoral thesis aimed to annalyse the historical trajectory of the feminine journal Escrínio, from Rio Grande do Sul, initially published in Bagé on January 2nd, 1898 and, later, edited in the Southern cities of Rio Grande do Sul: Rio Grande, Santa Maria and Porto Alegre, the latter being the one which ended the publishing on June 25th, 1910. Edited by the writer Andradina América de Andrada e Oliveira (1864-1935), the journal proved to be the basis for the consolidation of a communication network in the diverse relations established among the intellectual women in and outside the country. In this context, not only the journal was taken as primary source of research, but also the newspapers which were edited in distinct geopolitical spaces, pursuing a contact point between feminists from Portugal and Rio Grande do Sul (gaúchas). Simultaneously, the corpus of study was broadened, taking into account the insertion of Andradina in the literature universe through the examination of some of her literary work, which served as a platform for her critical speech down to the smallest detail of everyday life. Thus, this study enabled to see the link between the journal and its writer, who showed the evolutionary thought of feminism, promoting reflection towards gender, subjectivity and power relations in difficult times for the intelectual production of women from the nineteenth century

Severini e Denis

Severini risulta influenzato da Denis più di quanto sostenga negli scritti teorici. The Author examines the controversial relationships between the two artists, in the first decade of the century and later on, in their religious production.

The bed nucleus of the stria terminalis mediates inter-individual variations in anxiety and fear
No full textWhile learning to fear stimuli that predict danger promotes survival, the inability to inhibit fear to inappropriate cues leads to a pernicious cycle of avoidance behaviors. Previous studies have revealed large inter-individual variations in fear responding with clinically anxious humans exhibiting a tendency to generalize learned fear to safe stimuli or situations. To shed light on the origin of these inter-individual variations, we subjected rats to a differential auditory fear conditioning paradigm where one conditioned auditory stimulus (CS+) was paired to footshocks whereas a second (CS-) was not. We compared the behavior of rats that received pre-training excitotoxic lesions of the bed nucleus of the stria terminalis (BNST) to that of sham rats. Sham rats exhibit a continuum of anxious/fearful behaviors. At one end of the continuum were rats that displayed a poor ability to discriminate between the CS+ and CS-, high contextual freezing, and an anxiety-like trait in the elevated plus maze (EPM). At the other end were rats that display less fear generalization to the CS-, lower freezing to context, and a non-anxious trait on the EPM. Although BNST-lesioned rats acquired similarly high levels of conditioned fear to the CS+, they froze less than sham rats to the CS-. In fact, BNST-lesioned rats behaved like sham rats with high discriminative abilities in that they exhibited low contextual fear and a nonanxious phenotype in the EPM. Overall, this suggests that inter-individual variations in fear generalization and anxiety phenotype are determined by BNST influences on the amygdala and/or its targets.Published in Journal of Neuroscience.
