Purpose: To review the current advances and current of the study of consciousness in order to discuss the advantages of a research program on consciousness defined by biology and complexity sciences. Methodological design: A review of the scientific literature of consciousness showed conceptual and methodological findings and their limitations. An analysis of the methods of complexity sciences...
Consciousness is one of the most complex aspects of human experience. Studying the mechanisms involved in the transitions among different levels of consciousness remains as one of the greatest challenges in neuroscience. In this study we use a measure of integrated information (ΦAR) to evaluate dynamic changes during consciousness transitions. We applied the measure to intracranial...
AbstractThe point of departure of this paper is Penrose's definition of conscious action as that in which stimulus and response are linked by a non‐algorithmic relationship, which Penrose defines as ‘understanding’. My purpose is to explore the nature of this understanding by means of a two‐step process. The first step is provided by Tononi's Integrated Information Theory of consciousness. This...
The sense of agency, which refers to the subjective feeling of control, is an essential aspect of self-consciousness. We argue that distinguishing between the sensitivity and criterion of this feeling is important for discussing individual differences in the sense of agency and its connections with other cognitive functions.
Consciousness still remains puzzling and controversial. This paper demonstrates that at general and objective level, for understanding consciousness it is necessary to understand such fundamental concepts as contrast, interaction, complexity and emergence. New definitions of these terms are provided as they are erroneous or incomplete in their current form. The result of these investigations is...
Consciousness is the most precious function of brain; however, there is an explanatory gap between consciousness and matter, which is deemed to affect the scientific research on consciousness. We believe that a methodological trap commonly present in scientific research and the incompleteness of logic are the true reasons that affect the research on consciousness. Here, a novel logic tool, the...
Contemporary mind and brain sciences provide theories and data that seem to confirm a hypothesis about human nature that we might formulate as follows. Human life is conditioned by a need that is no less important than elementary biological needs (such as survival and reproduction) or universal forms of social competition: the need to build and, indeed, defend a subjective identity whose...
There is an urgent need for novel fast-acting antidepressants for adolescent treatment-resistant depression and/or suicidal risk, since the selective serotonin reuptake inhibitors that are clinically approved for that age (i.e., fluoxetine or escitalopram) take weeks to work. In this context, one of the main research lines of our group is to characterize at the preclinical level novel...

Background "Awe" is typically an inspiring emotional response to perceptually vast stimuli signifying the transcendence beyond all cognitive frames of reference when we encounter the unexpected. Physicians' experience of awe in clinical care interactions has not been studied in an empirical, evidence-based way. We aim to present a focused study of awe in a psychiatrist's empathic listening (EL)...
Psychedelics are being increasingly examined for their therapeutic potential in mood disorders. While the acute effects of ayahuasca, psilocybin, and lysergic acid diethylamide (LSD) last over several hours, inhaled N,N-Dimethyltryptamine (DMT) effects last around 10 min, which might provide a cost- and time-effective alternative to the clinical application of oral psychedelics. We aimed at...
