nature,nurture and nation: Nísia Floresta's engagement in the breast-feeding debate in Brazil and France

This article looks at the way the Brazilian writer and educator Nísia Floresta addresses issues of race and class within her construction of nationhood. This is achieved through a consideration of the specific subject of maternal breast-feeding as discussed by Floresta in two texts, written in Brazil and France, respectively. A comparison of these works reveals a very different engagement with race and class factors in determining women's claim to citizenship. Floresta, in common with early 19th-century European feminism, believed this claim to lie within the domestic sphere, primarily in the role of mother and educator. The article considers how, as a vital aspect of that role, she portrays maternal breast-feeding as both natural and patriotic. It also highlights the extent to which Floresta was influenced by the prevailing concerns of her contemporaries regarding the risks of wet nursing and the threat posed by household slaves, before going on to consider how this discourse leads Floresta to exclude black slave women from her vision of patriotic motherhood, while acknowledging the maternity of women of all classes in a European context. Patriotic concerns, shaped by racial prejudices, overshadow Floresta's feminism, prohibiting the kind of unifying discourse of motherhood, which she claimed to profess.     

Simulating Emotional Responses in Posttraumatic Stress Disorder: An fMRI Study

This study tested the extent to which coached participants can simulate the neural responses of participants with posttraumatic stress disorder (PTSD) when they are presented with signals of fear. Functional magnetic resonance imaging (fMRI) was used to study blood oxygenation level-dependent signal during the presentations of fearful and neutral faces under both conscious and nonconscious (masked) conditions. Participants comprised 12 patients with PTSD and 12 trauma-exposed controls who were instructed to simulate PTSD. During conscious fear processing, simulators showed greater activation in the left amygdala and medial prefrontal cortex (MPFC) than PTSD participants. By contrast, during nonconscious processing, PTSD participants had greater MPFC activation than simulators. These findings suggest that coached simulators produce a profile of ‘over-responding’ to fear when controlled conscious processing is possible, but are not able to simulate the exaggerated medial prefrontal responses observed in PTSD participants under conditions of nonconscious processing.
