A Hypothesis about parallelism vs. seriality in dreams
Barcaro U., Paradisi P., Sebastiani L.
The process of dream building implies the construction of a complex network of closely interrelated sources. On the other hand, the dream experience develops as a succession of events. In this paper a hypothesis is advanced about how the psycho-physiological system of dream building, which is distributed, acts to provide a serial output. This hypothesis is basically connected with the property, enjoyed by the dream experience, of simultaneously representing a plurality of meanings.Source: Frontiers in Psychology 10 (2019): 2299-1–2299-4. doi:10.3389/fpsyg.2019.02299

INTESA: an integrated ICT solution for promoting wellbeing in older people
Barcaro U., Barsocchi P., Crivello A., Delmastro F., Di Martino F., Distefano E., Dolciotti C., La Rosa D., Magrini M., Palumbo F.
As populations become increasingly aged, it is more important than ever to promote "Active Ageing" life styles among older people. Age-related frailty can influence an individual's physiological state making him more vulnerable and prone to dependency or reduced life expectancy. These health issues contribute to an increased demand for medical and social care, thus economic costs. In this context, the INTESA project aims at developing a holistic solution for older adults, able to prolong their functional and cognitive capacity by empowering, stimulating, and unobtrusively monitoring the daily activities according to well-defined "Active Ageing" life-style protocols.Source: AI*AAL.it 2017 Artificial Intelligence for Ambient Assisted Living, pp. 102–117, Bari, Italy, 16-17/11/2017

Long-term care: how to improve the quality of life with mobile and e-health services
Delmastro F., Dolciotti C., Palumbo F., Magrini M., Di Martino F., La Rosa D., Barcaro U.
In the last decade, ageing has become a worldwideincreasing phenomenon leading to an increased need forspecialised help. Continuous monitoring, training and rehabilitationimprove the quality of life of older adults and discardthe risk of depression and social isolation. To this end, the useof mobile and e-health personalised services at home and inresidential long-term care facilities can help to stabilise the healthconditions of the subjects, in terms of physical, mental, and socialcapabilities. In this context, we propose a set of personalisedmonitoring and rehabilitation services based on mobile, wearable,free contact, and touch screen technologies designed to providean integrated care and monitoring programme for elderly frailsubjects. We evaluated the proposed solutions by deploying theservices in a nursing home in Italy and defined customisedprotocols to involve both guests (primary users) and nursing carepersonnel (secondary users). In this paper, we present technicaldetails of the proposed solutions and the results obtained by therecently conducted surveys on the Quality of Experience anduser acceptance of both user categories after 4 months from thedeployment.Source: International Workshop on e-Health Pervasive Wireless Applications and Services 2018, in conjunction with 14th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob 2018), pp. 12–19, Limassol, Cyprus, 15-17 October 2018

Network properties of dream sources
Barcaro U., Carboncini M. C.
Vast research in the last decades has shed interesting light on a variety of heterogeneous systems, including the human brain, by studying their network properties. Our investigation aimed to see whether the system of dream sources and of the semantic links between them shares the network properties of the brain. The investigation was carried out by means of an appropriate graph representation of data obtained according to a protocol oriented to eliciting episodic dream sources. The main results were the following: most dream sources belonged to compact clusters; important hubs, i.e. sources very closely connected to numerous other sources, were present; the vertex-degree distribution presented two significant peaks; small-world properties were valid for most pairs of sources; forms of self-similarity or of partial self-similarity at different scales were observed; the graphs of dreams sources exhibited a very high level of integration between overlapping clusters.Source: International journal of dream research 11 (2018): 120–126. doi:10.11588/ijodr.2018.2.42736

Intermittency-driven complexity in the brain: towards a general-purpose event detection algorithm
Paradisi P., Righi M., Barcaro U., Salvetti O., Virgillito A., Carboncini M. C., Sebastiani L.
In this work we first discuss a well-known theoretical framework for the analysis and modeling of self-organized structures in complex systems. These self-organized states are metastable and rapid transition events mark the passages between self-organization and background or between two different self-organized states. Thus, our approach focuses on characterizing and modeling the complex system as a intermittent point process describing the sequence of transition events. Complexity is usually associated with the emergence of a renewal point process with power-law distributed inter-event times, hence the term fractal intermittency. This point process drives the self-organizing behavior of the complex system, a condition denoted here as intermittency-driven complexity. In order to find the underlying intermittent birth-death process of selforganization, we introduce and discuss a preliminary version of an algorithm for the detection of transition events in human electroencephalograms. As the sequence of transition events is known, the complexity of the intermittent point process can be investigated by applying an algorithm for the scaling analysis of diffusion processes driven by the intermittent process itself. The method is briefly illustrated by discussing some preliminary analyses carried out on real electroencephalograms.Source: , pp. 108–118, 2017

A protocol for eliciting dream associations oriented to the recognition of episodic dream sources
Barcaro U., Delogu A., Righi M., Virgillito A., Carboncini M. C.
The use of associations with dream reports, although being diffused and greatly useful in psychotherapy, has so far played a limited role in dream research not directly finalized to therapy. On the other hand, it is difficult to investigate a basic property of dreaming, that of establishing connections, without searching for information beyond the dream report: indeed, the simplest and likely most effective way of obtaining this information consists in asking the dreamer for associations. Well-defined and rigorous methods are however necessary for research approaches which aim to achieve a better understanding of how the dreaming mind operates by processing and combining the dreamer's memory sources: we propose an experimental protocol aiming to give a contribution in this direction. This protocol consists in asking the dreamer to complete a form which has been implemented so as to make it easier to recognize the sources of single dreams and to describe the link patterns among the sources; this form has been oriented to the identification of episodic sources, definite in space and time. To be more effective, the method takes advantage of the presence of a researcher while the dreamer is completing the form: the terms of the interaction between dreamer and researcher are subjected to marked restrictions and rigorously defined. The protocol was applied to a homogeneous group of participants; the observed link patterns presented interesting phenomena, whose occurrence was characterized by high statistical significance.Source: Dreaming (N.Y.N.Y.) 26 (2016): 79–93. doi:10.1037/drm0000019

The challenge of brain complexity - A brief discussion about a fractal intermittency-based approach
Paradisi P., Righi M., Barcaro U.
In the last years, the complexity paradigm is gaining momentum in many research fields where large multidimensional datasets are made available by the advancements in instrumental technology. A complex system is a multi-component system with a large number of units characterized by cooperative behavior and, consequently, emergence of well-defined self-organized structures, such as communities in a complex network. The self-organizing behavior of the brain neural network is probably the most important prototype of complexity and is studied by means of physiological signals such as the ElectroEncephaloGram (EEG). Physiological signals are typically intermittent, i.e., display non-smooth rapid variations or crucial events (e.g., cusps or abrupt jumps) that occur randomly in time, or whose frequency changes randomly. In this work, we introduce a complexity-based approach to the analysis and modeling of physiological data that is focused on the characterization of intermittent events. Recent findings about self-similar or fractal intermittency in human EEG are reviewed. The definition of brain event is a crucial aspect of this approach that is discussed in the last part of the paper, where we also propose and discuss a first version of a general-purpose event detection algorithm for EEG signals.Source: PhyCS 2016 - International Conference on Physiological Computing Systems 2016, pp. 123–129, Lisbona, Portugal, 27-28 June 2016

An automatic method for the study of REM sleep microstructure
Magrini M., Virgillito A., Barcaro U. Bonfiglio L., Pieri G. Salvetti O., Carboncini M. C
analysis of changes in polysomnographic signals during REM sleep. The implementation of the procedures has been motivated by the remarkable psychophysiological and clinical significance not only of REM sleep per se, but also of its microstructure, given by state variations at frequencies slower than 1 Hz. These procedures provide a segmentation of REM sleep into sub-stages and allow the calculation of quantitative parameters connected with the microstructural properties of REM sleep.Source: International Workshop on Computational Intelligence for Multimedia Understanding, Praga, Czech Republic, 28-30/10/2015

Three-chord harmonic sequences with unexpected out-of-key endings: are they suitable stimuli for eliciting N400 responses?
Virgillito A., Magrini M., Piarulli A., Bergamasco M., Barcaro U., Rossi B., Salvetti O., Carboncini M. C., Bonfiglio L.
A series of ERP components, each provided with both a precise timing with respect to stimulation and a specific cortical localization, reflects the temporal succession of processing stages of music information. We unexpectedly observed a N400-like component. This suggests that even chord-primed chord targets can convey extra-musical meanings and that, consequently, they might be useful in assessing residual higher-order information-processing capabilities in non-communicating patients with disorders of consciousness.Source: XXIII National Congress of the Italian Society of Psychophysiology, pp. 161–161, Lucca, Italy, 18-20/11/2015

N400-like responses to three-chord harmonic sequences with unexpected out-of-key endings: Scalp topography, cortical sources, and perspectives for a clinical use
Bonfiglio L., Virgilito A., Magrini M., Piaruli A., Bergamasco M., Barcaro U., Rosi B., Salvetti O., Carboncini M. C.
A series of ERP components, each provided with both a precise timing with respect to stimulation and a specific cortical localization, reflects the temporal succession of processing stages of music information. This makes the musical stimulus potentially usable to probe residual brain functions in non-communicating patients with disorders of consciousness. In an attempt to find a simple stimulation protocol that was suitable for use in a clinical setting, the purpose of this study was to verify whether a minimum-length musical stimulus, provided with a definite music-syntactic connotation, was still able to elicit musical ERPs in a group of eight healthy subjects. The stimulus was composed of the minimum number of chords necessary and sufficient to enable the subject to predict a plausible closure of the sequence (priming) and, at the same time, to provide him/her with the closing chord of the sequence (target), either congruous (probable closing) or not (improbable closing) to the tonal context. The subject's task was to discriminate and recognize the irregular targets. The components that were expected to be elicited, in this experimental situation, were ERAN, N5, P600/LPC. Conversely, in addition to these former components, we unexpectedly observed a N400-like component. To determine whether this component was a real N400, we submitted our data to a sLORETA analysis in order to identify its cortical generators. Irregular chords showed higher current densities with respect to regular ones on the right-sided medial and superior temporal gyri, superior and inferior parietal lobules, fusiform and parahippocampal gyri, and on the bilateral posterior cingulate cortex. In particular, the N400-like wave seems to share with the word-primed music-elicited N400 certain generators that are located in cortical areas BA 21/37 and BA 22. This suggests that even chord-primed chord targets can convey extra-musical meanings and that, consequently, they might be useful in assessing residual higher-order information-processing capabilities in non-communicating patients with disorders of consciousness.Source: Archives Italiennes de Biologie 153 (2015): 1–18.

Automatic segmentation of REM sleep into three substages
Magrini M., Virgillito A., Barcaro U., Bonfiglio L., Pieri G., Carboncini M. C.
The research aimed to introduce and test an automatic method for segmentation of REM sleep into three substages, respectively characterized by: enhancement of rapid eye movements; selective enhancement of slow eye movements (SEMs); reduction in the amount of eye movements. This objective was suggested by two kinds of data reported in the literature: distinction between phasic and tonic REM sleep, and remarkable presence of SEMs during REM sleep.Source: Journal of sleep research (Online) 23 (2014): 104–104. doi:10.1111/jsr.12213

A system for the automatic analysis of brain responses evoked by musical stimuli
Magrini M., Barcaro U.
The system described in this technical note was implemented for two purposes: (a) to produce stimuli, significant from the musical viewpoint, according to an appropriate protocol, (b) to acquire and process the Evoked Responses Potentials (ERPs) that are elicited as responses to these stimuli. This system was built within the scope of a research focused on the study of brain responses to musical stimuli. Recent literature about this topic has reported a number of significant results, which from the one hand have contributed to a better knowledge of the cognitive mechanisms of the human mind and, from the other, appear to suggest useful and important applications in the field of neurological clinics. Our research was carried out as a collaboration activity between researchers of the Signals and Images Laboratory of the ISTI and physicians of the Neuroscience Department of Pisa Hospital (Magrini et al., 2012; Carboncini et al., 2012; Virgillito et al, 2013a; Virgillito et al., 2013b). The system here described was devised as an integration of the BQ132S EEG amplifier (BrainQuick System, Micromed), which was used for recording electroencephalographic (EEG) signals.Source: ISTI Technical reports, 2014

A method for automatic REM sleep segmentation
Virgillito A., Barcaro U., Pieri G., Magrini M., Bonfiglio L., Carboncini M. C.
A basic property of REM sleep is that is not a uniform stage. Two kinds of variations are particularly significant. First, a remarkable amount of literature, based on polygraphic signals, fMRI images, and psychophysiological data, has shown that "phasic" epochs, presenting distinct oculomotor activity, should be distinguished from "tonic" epochs. Second, recent litarature has provided interesting data about slow eye movements (SEMs), which are present during REM sleep in addition to rapid eye movements (REMs), although, according to Rechtshaffen and Kales (1968), during REM sleep SEMs "do not approach the abundance magnitude, and pendular pattern of the slow eye movements during stage 1".Source: XXII National Congress of the Italian Society of Psychophysiology, pp. 130–131, Firenze, Italia, 27-29 November 2014

A cognitive model explaining the psychophysiological system responsible for the effectiveness of The Storytelling Method of Dream Interpretation
Barcaro U., Decicco L. T., Salvetti O.
Summary. The Storytelling Method of Dream Interpretation has been found to be valid and reliable while yielding a meaningful interpretation for dreamers more than 80% of the time. A cognitive model explaining the psychophysiological system responsible for the effectiveness of the method is proposed. The model describes a dream in terms of an input-output relationship where the dream-builder system is viewed as a system whose input is given by the dream sources and whose output is given by the dream experience. The model proposes a cascade of two sub-systems that can account for basic properties of dreams such as the continuity hypothesis, the role of dreams in turning-points of a dreamer's life, the problem-solving capacity of dreams, while accounting for the effectiveness of The Storytelling Method. An application of the model with the method is also demonstrated with an example.Source: International journal of dream research 5 (2012): 114–118. doi:10.11588/ijodr.2012.2.9245
