One contentious topic concerns the role of global signal (GS) fluctuations and how they affect more focal functional changes. Moreover, it has been difficult to pinpoint causal mechanisms of circuit disruption. Here, we analyzed resting-state fMRI data from 47 schizophrenia patients and 118 age-matched healthy controls and used dynamical analyses to investigate how global fluctuations and other functional metastable states are affected by this disorder. We found that brain dynamics in the schizophrenia group were characterized by an increased probability of globally coherent states and reduced recurrence of a substate dominated by coupled activity in the default mode and limbic networks. We then used the in silico perturbation of a whole-brain model to identify critical areas involved in the disease. Perturbing a set of temporo-parietal ...

However, its nature and psychological mechanisms remain obscure because studies often overlook the complexity of contour characterisation and disregard personal and contextual factors. To investigate the curvature effect, we propose a continuous and multidimensional manipulation and contrasting experimental conditions examined at the group and individual levels that unveil a complex picture, not reducible to monotonous relationships: Perceptual and hedonic evaluations relied on multiple geometric features defining contour and shape. These features were specifically weighted to characterise each construct, depending on the individual and contingent on whether evaluating perceptually or hedonically. Crucially, the curvature effect was not robust to preference with respect to the median and continuous manipulations of contour for varying shapes. As curved contours are more easily pe...

In its first part, the chapter reviews the advances in EEG biomarkers for epileptic network mapping in both invasive and scalp EEG, including univariate epileptogenic indexes linear connectivity measures within the multivariate autoregressive model, non-linear correlation measures and graph-theoretical properties. In the second part, the chapter covers some of the initial contributions to characterize network dynamics in epilepsy. Particular attention is paid at the seizure prediction problem, using classic dynamical systems approaches as well as the most recent machine-learning prediction algorithms and network-science studies unraveling signatures of the transition from interictal to ictal activity

Però hom s’enfronta a uns poemes farcits de neologismes, ressonàncies i referències a les tradicions alemanya i hebrea. En aquest article discutim les dificultats que planteja la traducció de Todesfuge i confrontem diferents versions que han aparegut en català, castellà i anglès. De totes, les més destacades no són aquelles que se senten lligades a l’original, sinó les que l’agafen com a interlocutor per obrir una conversa fructífera. El traductor esdevé així el Tu abastable que reclamava Celan i resta obert al diàleg: el seu poema és una possible resposta al missatge que li arriba tancat dins d’una ampolla i que rescata de l’oblit.Translating Paul Celan’s poetry is a matter of responsibility because it makes us reflect on the validity of western principles, whi...

In this thesis, we investigate how a number of computational approaches can be used to analyze human intracranial recordings to shed light on specific questions of both clinical and cognitive nature. With this regard, we first conceptualize the problem of mapping human brain networks from EEG with existing data-driven and model-based methods. Building on recent advances, we propose a new strategy to detect the epileptic focus based on a seizure-specific identification of spectral patterns in the time and frequency domains. Along the cognitive line, we develop a novel analytical framework relying on intracranial recordings to assess the level of influence of local neural activations on the brain’s global state during cognition.L’electroencefalografia intracrani...

It consists of four subsets of 50 stimuli varying in balance, contour, symmetry, or complexity. All are 4 s long and designed to be musically appealing and experimentally controlled. We assessed them behaviorally and computationally. The behavioral assessment (Study 1) aimed to determine whether musically untrained participants could identify variations in each attribute. Forty-three participants rated the stimuli in each subset on the corresponding attribute. We found that inter-rater reliability was high and that the ratings mirrored the design features well. Participants’ ratings also served to create an abridged set of 24 stimuli per subset. The computational assessment (Study 2) required the development of a specific battery of computational measures describing the structural properties of each stimulus. We distilled nonredundant composite measures ...

Second-phase pre-surgical monitoring was performed using SEEG due to lesion-negative imaging and the rare semiology. The seizure onset zone was delimited to the right anterior hippocampus and the temporobasal cortex, with the propagation zone within the entorhinal cortex. Interestingly, direct electrical stimulation to the entorhinal cortex, which was reproduced in a number of trials, evoked spitting without leading to seizures or post-discharges. After the resection of the epileptogenic zone, the patient remained seizure-free without AEDs for a follow-up period of five years (Engel Class 1a). The neuropathology revealed a focal cortical dysplasia type FCD-Ia. Spectral analysis of intracranial ictal EEG (iEEG) data suggested a possible role of the basal temporal and entorhinal cortex as a necessary node in ictal spitting.
