Role of Single Low Pulse Intensity of Transcranial Magnetic Stimulation Over the Frontal Cortex for Cognitive Function

2020

Background: The principal aim of this study was to measure the effect of online single-pulse transcranial magnetic stimulation (TMS) over the right dorsolateral prefrontal cortex (DLPFC) on cognition via the Cambridge Neuropsychological Test Automated Battery (CANTAB) in healthy individuals. Methods: In a single-blind, sham-controlled study, we assessed both 50% and 60% of the resting motor threshold (RMT) over the right DLPFC in healthy right-handed (n = 42) adults using cognitive function, such as attention and memory, as a measure via CANTAB. Results: We observed an improvement in the cognitive function level during the use of online low intensities of 50% and 60% RMT active stimulation …

Cognitive Performance and Psychological Distress in Breast Cancer Patients at Disease Onset

2019

ObjectiveMany cancer patients complain about cognitive dysfunction. While cognitive deficits have been attributed to the side effects of chemotherapy, there is evidence for impairment at disease onset, prior to cancer-directed therapy. Further debated issues concern the relationship between self-reported complaints and objective test performance and the role of psychological distress.MethodWe assessed performance on neuropsychological tests of attention and memory and obtained estimates of subjective distress and quality of life in 27 breast cancer patients and 20 healthy controls. Testing in patients took place shortly after the initial diagnosis, but prior to subsequent therapy.ResultsWhi…

Quadrature domains for the Helmholtz equation with applications to non-scattering phenomena

2022

In this paper, we introduce quadrature domains for the Helmholtz equation. We show existence results for such domains and implement the so-called partial balayage procedure. We also give an application to inverse scattering problems, and show that there are non-scattering domains for the Helmholtz equation at any positive frequency that have inward cusps.

Differential of metric valued Sobolev maps

2020

We introduce a notion of differential of a Sobolev map between metric spaces. The differential is given in the framework of tangent and cotangent modules of metric measure spaces, developed by the first author. We prove that our notion is consistent with Kirchheim's metric differential when the source is a Euclidean space, and with the abstract differential provided by the first author when the target is $\mathbb{R}$.

Analysis of HLA-DRB1,DQA1,DQB1 haplotypes in Sardinian centenarians

2008

Some genetic determinants of longevity might reside in those polymorphisms for the immune system genes that regulate immune responses. Many longevity association studies focused their attention on HLA (the human MHC) polymorphisms, but discordant results have been obtained. Sardinians are a relatively isolate population and represent a suitable population for association studies. Some HLA-DR and DQ alleles form very stable haplotypes with a strong linkage disequilibrium. In a previous study on Sardinian centenarians we have suggested that HLA-DRB1 *15 allele might be marginally associated to longevity. HLA-DR,DQ haplotypes are in strong linkage disequilibrium and well conserved playing a ro…

What makes us like music?

2009

Why do we like the music we like and why do different people like different kinds of music? Existing models try to explain music preference as an interplay of musical features, the characteristics of the listener, and the listening context. Hereby, they refer to short-term preference decisions for a given piece of music rather than to the question why we listen to music at all and why we select a particular musical style. In this paper, it is hypothesized that the motivation for music listening and the liking for a particular kind of music depend on the functions that this music can fulfill for the listener. Thus, the relative contribution of these functions to the development of music pref…

Emotions of music listening in Finland and in India : Comparison of an individualistic and a collectivistic culture

2020

Music is appreciated for emotional reasons across cultures, but knowledge on the cross-cultural similarities and differences of music-evoked emotions is still sparse. The current study compared music-evoked emotions in Finland and in India, contextualizing them within the perceived psychological functionality of music in an individualistic versus collectivistic culture. Participants ( N = 230) answered an online survey on music-evoked emotions and related personal meanings. A mixed-method approach using factor analysis and qualitative content analysis was used to identify the concepts for cross-cultural comparison. Results show that both cultures value music for positive emotional experien…

Brain and body percussion : the relationship between motor and cognitive functions

2015

The focus of this thesis is the relationship between embodied motor rhythmic exercises (e.g. body percussion) and executive functions. Decades’ long successful application of this method within general classrooms and in music education led to the hypothesis that body percussion could have a positive impact on core cognitive functions also referred to as executive functions. Two pilot experiments were conducted to test proper settings for investigating the above-mentioned relationship. Experiment 1 piloted the use of neuropsychological tests with pre- and post-measures of the Tower of London (TOL) neuropsychological test. Experiment 2 piloted the use of an electroencephalography (EEG) device…
