No full textGli avantesti delle opere abbandonate. Georges Perec e la disseminazione dei fantasmi del romanzo
No full textThe abandoned work is a form of voluntary incompletion because the interruption of the writing process is decided by the author himself. Abandonment is preceded by considerations and traces that make the process intelligible, especially when identified in avant-textual documents in which the author often not only plans the construction of the text but also reasons about it by tracing the criticalities that condition its progress. The article aims to reflect on some aspects of Georges Perec's abandoned works, showing how these are integrated within the completed works through the processes of dissemination and proliferation
Edelman, G., Tononi, G. A universe of consciousness: how matter becomes imagination
No full textGerald M. Edelman, Giulio Tononi. A universe of consciousness: how matter becomes imagination
In A Universe of Consciousness, Gerald Edelman builds on the radical ideas he introduced in his monumental trilogy-Neural Darwinism, Topobiology, and The Remembered Present-to present for the first time an empirically supported full-scale theory of consciousness. He and the neurobiologist Giulio Tononi show how they use ingenious technology to detect the most minute brain currents and to identify the specific brain waves that correlate with particular conscious experiences. The results of this pioneering work challenge the conventional wisdom about consciousness.https://digitalcommons.rockefeller.edu/ru-authors/1052/thumbnail.jp

How to decode data files
File "Data/HydroCelGSN256v10.sfp" gives the channel locations for all PSGs. It is a BESA surface point coordinate or EGI-xyz Cartesian coordinate file (.sfp); details about this format may be found at http://wiki.besa.de/index.php?title=Working_With_Additional_Files&oldid=5145.

Experimental description
Procedure. The procedure used in this study has been described in detail in a previous publication9. Awakenings in the sleep laboratory were performed at pseudorandom intervals, irrespective of sleep stage, using a computerized sound that lasted 1.5 s, which was administered through E-Prime (Psychology Software Tools, Pittsburgh, PA). Subjects were instructed to signal that they had heard the alarm sound and to lie quietly on their back. They then underwent a structured interview via intercom about their mental activity that lasted between 20 s and 3.5 min, depending on whether the subject reported a conscious experience and had to answer additional questions related to the content. Signed informed consent was obtained from all participants before the experiment, and ethical approval for the study was obtained from the University of Wisconsin–Madison Institutional Review Board. Data collection and analysis were not performed blind to the conditions of the experiments.
Study participants in experiment 1. Thirty-two healthy subjects (12 males, age 46 ± 13.3 years (mean ± s.d.), range 24–65 years), selected from a group of 69 subjects participating in a larger research project in our laboratory, were included in this experiment. Subjects were randomly selected from the subset of all participants that had at least one DE and NE report in NREM sleep during the same night. Among the 240 awakenings performed in these 32 subjects, 5 had to be excluded for technical problems and 2 because subjects were too somnolent upon awakening to answer questions reliably. Comparisons between DEWR–NE conditions and DE–DEWR conditions were performed in the subset of these participants (N = 20) that had all three types (DE, DEWR, NE) of report during the same night. In REM sleep, only 6 of the 69 participants presented both DE and NE. They were all included in the analysis.
Sleep recordings. Recordings were made at the Wisconsin Center for Sleep and Consciousness. They were performed using a 256-channel high-density EEG (hd-EEG) system (Electrical Geodesics, Inc., Eugene, Ore.). Four of the 256 electrodes placed at the outer canthi of the eyes were used to monitor eye movements; additional polysomnography channels were used to record submental electromyography. Sleep scoring was performed over 30-s epochs, according to standard criteria.
DREAM categorization procedure
We have converted dream categories in Records.csv as DE = Experience, DEWR = Experience without recall, NE = No Experience.

Why does consciousness fade in early sleep?
No full textConsciousness fades during deep nonrapid eye movement (NREM) sleep early in the night, yet cortical neurons remain active, keep receiving sensory inputs, and can display patterns of synchronous activity. Why then does consciousness fade? According to the integrated information theory of consciousness, what is critical for consciousness is not firing rates, sensory input, or synchronization per se, but rather the ability of a system to integrate information. If consciousness is the capacity to integrate information, then the brain should be able to generate consciousness to the extent that it has a large repertoire of available states (information), yet it cannot be decomposed into a collection of causally independent subsystems (integration). A key prediction stemming from this hypothesis is that such ability should be greatly reduced in deep NREM sleep; the dreamless brain either breaks down into causally independent modules, shrinks its repertoire of possible responses, or both. In this article, we report the results of a series of experiments in which we employed a combination of transcranial magnetic stimulation and high-density electroencephalography (TMS/hd-EEG) to directly test this prediction in humans. Altogether, TMS/hdEEG measurements suggest that the sleeping brain, despite being active and reactive, loses its ability of entering states that are both integrated and differentiated; it either breaks down in causally independent modules, responding to TMS with a short and local activation, or it bursts into an explosive and aspecific response, producing a full-fledged slow wave
L’EBREO CAMALEONTE DI PATRICK MODIANO: STRATEGIE DI DECOSTRUZIONE DELLA LETTERATURA IDEOLOGICAMENTE ORIENTATA
No full text"Place de l’étoile"- romanzo d’esordio del giovanissimo Patrick Modiano - complesso nella sua forma poiché caratterizzato da un vertiginoso trasformismo stilistico, mette in scena attraverso accumulazione paradossale, l’ironia sacralizzante e una sensibilità desacralizzante autori, intellettuali e personaggi, ebrei, nazisti, collaborazionisti nel tentativo di destrutturare i modelli stereotipati del collaborazionista, del resistente e dell’ebreo e di rovesciare proprio quell’interpretazione sociologica che di quest’ultimo Sartre ci da nelle sue "Riflessioni sulla questione ebraica". Tuttavia Place de l’étoile dietro la denuncia del collaborazionismo francese manifesta anche la fermentazione di un scrittura che diventa atto sovversivo nei confronti di quella letteratura fortemente ideologizzata evocata all’interno del romanzo e neutralizzata attraverso un sistema complesso di citazioni e allusioni
"Le livre des fuites" : la violence et le vertige du mouvement
No full textLe livre des fuites est un mouvement complexe qui englobe et qui engloutit le lecteur, la narration, la langue. En effet, le titre autoréférentiel et métaleptique anticipe le brouillage des niveaux narratifs qui se superposent et se questionnent dans le roman : l’alternance des récits à la première et à la troisième personne, les chapitres « Autocritiques » qui interrogent la création même, les espaces blancs, la création d’une fiction dystopique, l’alternance des silences et des bruits, le relativisation du concept de mouvement. Ainsi on essayera d’analyser les différentes typologies de violence : la violence scripturale qui par l’emploi des phrases nominales, des listes, des phrases minimes impose une narration fragmentaire ; la violence du monde moderne qui provoque l’aliénation de l’homme et qui se traduit dans le texte par l’anthropomorphisation de la ville, par l’opposition silence/bruit, où le silence est conçu comme « accession à un domaine extérieur au langage », par la création d’une fiction dystopique dominée par la synesthésie ; la violence qui provoque le vertige du lecteur qui assiste à la déstructuration du roman et à l’imposition d’un mouvement incessant, une fuite labyrinthique et cyclique, un voyage vers la conscience

No full textGli scavi e la sequenza
No full textGli scavi eseguiti nel 2004 hanno messo in luce una chiesa datata tra fine VI e inizi VII secolo che alla metà del VII viene provvista di un loculo per reliqui e di un nuovo altare su podio. Contemporaneamente vengono deposte all'interno due sepolture, in una delle quali sono stati rinvenuti una ventina di elementi di cinture molteplici longobarde. L'abside viene ricostruita in epoca romanica
