Ladinia dolomitica
2020
Scopo di questo contributo è offrire una panoramica sull’area che viene usualmente definita “Ladinia dolomitica” e sulla varietà linguistica che vi viene tradizionalmente parlata, il ladino. L'articolo descrive brevemente la storia dell'area e dello sviluppo del ladino, e in seguito descrive le caratteristiche fonologiche, morfologiche, sintattiche e lessicali principali del ladino, che lo distinguono dalle vicine varietà italoromanze. In seguito si illustrano le peculiarità linguistiche dei singoli dialetti ladini, che sono parlati ognuno in una valle diversa delle Dolomiti. L'articolo è fortemente innovativo e originale, perché permette di ascoltare i file audio che esemplificano i tratti…
An Information-Theoretic Framework to Measure the Dynamic Interaction between Neural Spike Trains
2021
Understanding the interaction patterns among simultaneous recordings of spike trains from multiple neuronal units is a key topic in neuroscience. However, an optimal approach of assessing these interactions has not been established, as existing methods either do not consider the inherent point process nature of spike trains or are based on parametric assumptions that may lead to wrong inferences if not met. This work presents a framework, grounded in the field of information dynamics, for the model-free, continuous-time estimation of both undirected (symmetric) and directed (causal) interactions between pairs of spike trains. The framework decomposes the overall information exchanged dynami…
Food supplementation reveals constraints and adaptability of egg quality in the magpie Pica pica
2015
Differences in the deposition of limited maternal resources to eggs can reflect the optimal allocation to manipulate offspring phenotype, or constraints caused by maternal condition. We examined multiple maternal substances transferred to eggs in the magpie Pica pica to test the hypothesis that certain substances represent constraint and some optimal allocation. We did this by supplementary feeding magpies prior to egg-laying and then comparing the effect of food on maternal substances in conjunction with laying order relative to a control group. Certain substances such as carotenoids, immunoglobulins and avidin responded positively to food supplementation, whereas others, such as testoste…
Musical interaction in music therapy for depression treatment
2022
Music therapy is efficacious for the treatment of depression. Compared to other psychotherapeutic forms, it allows for the emergence of various modes of mutual interaction, thus enabling multiple channels for emotional expression and fostering therapeutic alliance. Although musical interaction patterns between client and therapist have been regarded as predictors of therapeutic outcome in depression, this has not yet been systematically investigated. We aim to address this gap by analyzing the possible linkage between musical interaction features and changes in depression score. In a clinical trial, digital piano improvisations from 58 Finnish clients and their therapists were recorded ove…
A comparison of methods for investigating the perceptual center of musical sounds
2019
In speech and music, the acoustic and perceptual onset(s) of a sound are usually not congruent with its perceived temporal location. Rather, these "P-centers" are heard some milliseconds after the acoustic onset, and a variety of techniques have been used in speech and music research to find them. Here we report on a comparative study that uses various forms of the method of adjustment (aligning a click or filtered noise in-phase or anti-phase to a repeated target sound), as well as tapping in synchrony with a repeated target sound. The advantages and disadvantages of each method and probe type are discussed, and then all methods are tested using a set of musical instrument sounds that syst…
Does conal prime CANAL more than cinal? Masked phonological priming effects in Spanish with the lexical decision task.
2005
Evidence for an early involvement of phonology in word identification usually relies on the comparison between a target word preceded by a homophonic prime and an orthographic control (rait-RATE vs. raut-RATE). This comparison rests on the assumption that the two control primes are equally orthographically similar to the target. Here, we tested for phonological effects with a masked priming paradigm in which orthographic similarity between priming conditions was perfectly controlled at the letter level and in which identification of the prime was virtually at chance for both stimulus onset asynchronies (SOAs) (66 and 50 msec). In the key prime-target pairs, each prime differed from the targ…
Role of cardiac dyssynchrony and resynchronization therapy in functional mitral regurgitation
2016
Functional mitral regurgitation (FMR) is a common complication of left ventricle (LV) dysfunction and remodelling. Recently, it has been recognized as an independent prognostic factor in both ischaemic and non-ischaemic LV dysfunctions. In this review article, we discuss the mechanisms through which cardiac dyssynchrony is involved in FMR pathophysiologic cascade and how cardiac resynchronization therapy (CRT) can have therapeutic effects on FMR by reverting specific dyssynchrony pathways. We analyse recent clinical trials focusing on CRT impact on FMR in 'real-world' patients, the limits and future perspectives that could eventually generate new predictors of CRT response in terms of FMR r…
Dance on cortex: enhanced theta synchrony in experts when watching a dance piece
2018
When watching performing arts, a wide and complex network of brain processes emerge. These processes can be shaped by professional expertise. When compared to laymen, dancers have enhanced processes in observation of short dance movement and listening to music. But how do the cortical processes differ in musicians and dancers when watching an audio-visual dance performance? In our study, we presented the participants long excerpts from the contemporary dance choreography of Carmen. During multimodal movement of a dancer, theta phase synchrony over the fronto-central electrodes was stronger in dancers when compared to musicians and laymen. In addition, alpha synchrony was decreased in all gr…
Turning Heads on the Dance Floor: Synchrony and Social Interaction Using a Silent Disco Paradigm
2023
Music and dance appear to have a social bonding effect, which some have theorized is part of their ultimate evolutionary function. Prior research has also found a social bonding effect of synchronized movement, and it is possible that interpersonal synchrony could be considered the “active ingredient” in the social bonding consequences of music or dance activity. The present study aimed to separate the effects of synchrony from other factors associated with joint experience of dancing by using a “silent disco” manipulation, in which the timing of a musical stimulus was varied within a dyad in a freestyle dance setting. Three conditions were included: synchrony, tempo-shifted (in which the …
