OBJECTIVE To demonstrate that the classical calculation of Lempel-Ziv complexity (LZC) has an important limitation when applied to EEGs with rapid rhythms, and to propose a multiscale approach that overcomes this limitation. METHODS We have evaluated, both with simulated and real EEGs, whether LZC calculation neglects functional characteristics of rapid… (More)
Although there is an extensive literature on the study of the neural correlates of consciousness (NCC) this is a subject that is far from being considered over. In this paper we present a novel experimental paradigm, based on binocular rivalry, to study internally and externally generated conscious experiences. We called this procedure bimodal rivalry. In… (More)
Cognitive functions result from the interplay of distributed brain areas operating in large-scale networks. These networks can be modelled with a number of parameters that represent their underlying dynamics. One particularly fruitful model to simulate key aspects of the large-scale brain networks is the Kuramoto model, which simulates the phase evolution… (More)
Mind wandering (MW) can be understood as a transient state in which attention drifts from an external task to internal self-generated thoughts. MW has been associated with the activation of the Default Mode Network (DMN). In addition, it has been shown that the activity of the DMN is anti-correlated with activation in brain networks related to the… (More)

Extrapyramidal symptoms (EPS) associated with antipsychotic medication can provoke severe discomfort and disability. Some instruments have been proposed to assess EPS, but they are not widely used in clinical settings. This paper aims to provide a translational tool for the detection of EPS: lacunarity of patients' handwritings. Lacunarity is a measure,… (More)
