MB2017: Artificial spiking neural data with ground truth
No full textThis dataset comprises simulated extracellular spiking neural signals, for which the activity of the active neurons is known. These data can thus be used to test spike sorting algorithms.

Combined macro-/mesoporous microelectrode arrays for low-noise extracellular recording of neural networks
No full textMicroelectrode arrays (MEAs) are appealing tools to probe large neural ensembles and build neural prostheses. Microelectronics microfabrication technologies now allow building high-density MEAs containing several hundreds of microelectrodes. However, several major problems become limiting factors when the size of the microelectrodes decreases. In particular, regarding recording of neural activity, the intrinsic noise level of a microelectrode dramatically increases when the size becomes small (typically below 20-?m diameter). Here, we propose to overcome this limitation using a template-based, single-scale meso- or two-scale macro-/mesoporous modification of the microelectrodes, combining the advantages of an overall small geometric surface and an active surface increased by several orders of magnitude. For this purpose, standard platinum MEAs were covered with a highly porous platinum overlayer obtained by lyotropic liquid crystal templating possibly in combination with a microsphere templating approach. These porous coatings were mechanically more robust than Pt-black coating and avoid potential toxicity issues. They had a highly increased active surface, resulting in a noise level ?3 times smaller than that of conventional flat electrodes. This approach can thus be used to build highly dense arrays of small-size microelectrodes for sensitive neural signal detection
Ethos et représentation de l'Autre dans le discours de controverse religieuse de Philippe Duplessis-Mornay : Étude de l'emploi des pronoms dans la préface de deux éditions du Traité de l'eucharistie (1598/1604)
No full textWith the discourse analysis as framework, this study focuses on the ethos, the representation of the Other and the argumentation in the discourse of religious controversy of the protestant Philippe Duplessis-Mornay. The corpus, which consists of the prefaces of two editions of the Traité de l’eucharistie (1598 and 1604), was subject to a systematic survey of the personal pronouns je, nous, vous as well as references to Duplessis-Mornay’s direct opponents, in a diachronic perspective (the two editions have been compared). The analysis has shown the discursive strategies of Duplessis-Mornay, including a subtle management of the ethos and the relationship with the Other in order to convince the reader. The build-up of an ethos by an interposed author (frequent use of quotations), observed in the edition of 1598, has increased in that of 1604. This edition is also characterized by an ethos of justification which intends to invalidate an unfavourable prediscursive ethos resulting from adverse reactions to the first edition. The ethos of caritas and the authorial ethos are also very present in the discourse of the author in both editions. In his relation to the Other, Duplessis-Mornay uses a strategic approach, alternating nous inclusif and nous exclusif, and referring most often the notion of vous dans l’erreur to authors recognized by Catholics themselves, through quotations. Only direct opponents of the author are stigmatized by their representation in the third person. Duplessis-Mornay’s discourse, in both prefaces, is characterized by a diplomatic and persuasive attitude

Status of the Virgo experiment
No full textThe concepts of anthropology and communication have a number of interpretive elements and themes in common: the importance of relationships, the place of man in nature, the human way of knowing. There are also differences: ethics and violence are part of the anthropological domain, but not of communication. This does not prevent the SIC to claim that they have something new to say about mankind. So what could an anthropology of communication be? A sort of ethnography describing how individuals communicate? This is not enough. Communication research also includes presuppositions about humans which support its positions on the relationship with machines, the comprehension of information and the reception of the media. Finally one would define anthropology of communication as various images of human elements which exist more or less explicitly in the minds of researchers working in communications and to which they refer for their interpretation as well as their hypotheses. We therefore have not ONE SINGLE anthropology of communication but A RANGE OF anthropologies which form the basis of communications research. One needs to unearth them through an epistemological approach
