Resumo: O artigo trata da especificidade de um dos produtos tecnológicos de vigilância e de ataque aéreos mais importantes em uso atualmente, os drones, mostrando em que sentido essa nova tecnologia traça um marco decisivo na evolução do domínio dos ares e, portanto, como sugere Carl Schmitt, na transformação do campo teológico-político das sociedades contemporâneas. A imanência radical do campo político proposta pelo liberalismo, diagnosticada por Schmitt, terá nos drones um de seus instrumentos mais exemplares. Para caracterizar a especificidade dos (...) drones frente a outros aparelhos visuais e aéreos de guerra, será proposta uma aproximação com o conceito de imagem-tempo de Gilles Deleuze, de tal modo a determinar essa sua singularidade a partir das propriedades intrínsecas da imagem gerada. A principal característica da imagem-tempo deleuziana a ser integrada à análise dos drones será seu aspecto tátil. Nesse momento, a aproximação dos livros de Deleuze sobre o cinema com sua obra escrita com Félix Guattari será essencial para determinar a dimensão política da imagem-drone.: This paper deals with the specificity that characterizes one of the most important technological aerial products dedicated to surveillance and attack being in use nowadays, the drones, showing in which sense this new technology is a decisive turning point in the evolution of the domination of the skies and therefore, as suggested by Carl Schmitt, in the transformation of the political-theological field in contemporary societies. The radical immanence of the political field proposed by liberalism, such as Schmitt described it, finds in drones one of its most typical instruments. To characterize the specificity of drones regarding other visual and aerial war machines, it will be proposed an approximation with the Deleuzian concept of image-time, in order to determine its singularity through the intrinsic properties of the images so produced. The main characteristic of the Deleuzian time-image to be integrated in the analysis of drones will be its haptic aspect. At this point, the relation between Deleuze’s cinema books and his work in collaboration with Félix Guattari will be essential to characterize the political dimension of the drone-image. (shrink)

Background: Freezing of gait is a common symptom in Parkinson’s disease and can be difficult to treat with dopaminergic medications or with deep brain stimulation. Novel stimulation paradigms have been proposed to address suboptimal responses to conventional DBS programming methods. Burst-cycling deep brain stimulation delivers current in various frequencies of bursts, while maintaining an intra-burst frequency identical to conventional DBS.Objective: To evaluate the safety and tolerability of BCDBS in PD patients with FOG.Methods: Ten PD subjects with STN or GPi DBS (...) and complaints of FOG were recruited for this single center, single blinded within-subject crossover study. For each subject, we compared 4, 10, and 15 Hz BCDBS to conventional DBS during the PD medication-OFF state.Results: There were no serious adverse events with BCDBS. It was feasible and straightforward to program BCDBS in the clinic setting. The benefit was comparable to conventional DBS in measures of FOG, functional mobility and in PD motor symptoms. BCDBS had lower battery consumption when compared to conventional DBS.Conclusions: BCDBS was feasible, safe and well tolerated and it has potential to be a viable future DBS programming strategy.
