Corrigendum: Psychological Effects of a 1-Month Meditation Retreat on Experienced Meditators: The Role of Non-attachment

Tracking Changes in Frontal Lobe Hemodynamic Response in Individual Adults With Developmental Language Disorder Following HD tDCS Enhanced Phonologic…
2020
Background: Current research suggests a neurobiological marker of developmental language disorder (DLD) in adolescents and young adults may be an atypical neural profile coupled with behavioral performance that overlaps with that of normal controls. Although many imaging techniques are not suitable for the study of speech and language processing in DLD populations, fNIRS may be a viable option. In this study we asked if fNIRS can be used to identify atypical cortical activation patterns in individual adults with DLD and track potential changes in cortical activation patterns following a phonological working memory training protocol enhanced with anodal HD tDCS stimulation to the presuppleme…
Exploring EEG recordings of Focused Attention Meditation with Fourier-ICA
2017
Meditaation harjoittamiseen liitetään usein useita terveyshyötyjä. Elektroenkefalografia (EEG)-menetelmällä on mahdollista seurata hermostossa meditaatioistunnon aikana tapahtuvia ajallisia muutoksia. Löydöt tällä alueella antaisivat lisää tietoa erityisesti meditaation aivovasteista, mutta myös yleisempää tietoa aivojen toiminnasta luonnollisissa olosuhteissa. Tässä tutkielmassa käytetään Fourier-ICA:ksi kutsuttua itsenäisten komponenttien analyysin muunnelmaa meditaatioistunnoista saatujen EEG-aineistojen analyysiin ja näytetään että itsenäisten komponenttien analyysiä voi käyttää muuhunkin kuin vain häiriöiden poistamiseen, mikä on sen tavallisin käyttötapaus EEG-tutkimuksissa. Erityises…

Organy w utworze Medytacje Tomasza Kulikowskiego
2019
This article contains the results of the analysis of the piece Meditations by Tomasz Kulikowski. He is a contemporary Polish composer, organist and teacher. The first part of the article is devoted to his life and work. The next one presents the circumstances of the creating the composition, with particular regard to the title given. Meditations were written in 2003. It is a chamber piece for the organ and cello. The third part contains an analysis of the composition structure. The significance of the organ for various elements of the work turned out to be extremely interesting. Their functions are described in the fourth part.
Fiberless, Multi-Channel fNIRS-EEG System Based on Silicon Photomultipliers: Towards Sensitive and Ecological Mapping of Brain Activity and Neurovasc…
2020
Portable neuroimaging technologies can be employed for long-term monitoring of neurophysiological and neuropathological states. Functional Near-Infrared Spectroscopy (fNIRS) and Electroencephalography (EEG) are highly suited for such a purpose. Their multimodal integration allows the evaluation of hemodynamic and electrical brain activity together with neurovascular coupling. An innovative fNIRS-EEG system is here presented. The system integrated a novel continuous-wave fNIRS component and a modified commercial EEG device. fNIRS probing relied on fiberless technology based on light emitting diodes and silicon photomultipliers (SiPMs). SiPMs are sensitive semiconductor detectors, whose large…

Prismatic adaption (PA) has been proposed as a tool to induce neural plasticity and is used to help neglect rehabilitation. It leads to a recalibration of visuomotor coordination during pointing as well as to aftereffects on a number of sensorimotor and attention tasks, but whether these effects originate at a motor or attentional level remains a matter of debate. Our aim was to further characterize PA aftereffects by using an approach that allows distinguishing between effects on attentional and motor processes. We recorded EEG in healthy human participants (9 females and 7 males) while performing a new double step, anticipatory attention/motor preparation paradigm before and after adaptat…

It's Sad but I Like It The Neural Dissociation Between Musical Emotions and Liking in Experts and Laypersons
2016
Emotion-related areas of the brain, such as the medial frontal cortices, amygdala, and striatum, are activated during listening to sad or happy music as well as during listening to pleasurable music. Indeed, in music, like in other arts, sad and happy emotions might co-exist and be distinct from emotions of pleasure or enjoyment. Here we aimed at discerning the neural correlates of sadness or happiness in music as opposed those related to musical enjoyment. We further investigated whether musical expertise modulates the neural activity during affective listening of music. To these aims, 13 musicians and 16 non-musicians brought to the lab their most liked and disliked musical pieces with a …
Dynamics of brain activation during learning of syllable-symbol paired associations.
2019
| openaire: EC/H2020/641652/EU//ChildBrain Initial stages of reading acquisition require the learning of letter and speech sound combinations. While the long-term effects of audio-visual learning are rather well studied, relatively little is known about the short-term learning effects at the brain level. Here we examined the cortical dynamics of short-term learning using magnetoencephalography (MEG) and electroencephalography (EEG) in two experiments that respectively addressed active and passive learning of the association between shown symbols and heard syllables. In experiment 1, learning was based on feedback provided after each trial. The learning of the audio-visual associations was c…
