Neural generators of the frequency-following response elicited to stimuli of low and high frequency: A magnetoencephalographic (MEG) study.

2021

The frequency-following response (FFR) to periodic complex sounds has gained recent interest in auditory cognitive neuroscience as it captures with great fidelity the tracking accuracy of the periodic sound features in the ascending auditory system. Seminal studies suggested the FFR as a correlate of subcortical sound encoding, yet recent studies aiming to locate its sources challenged this assumption, demonstrating that FFR receives some contribution from the auditory cortex. Based on frequency-specific phase-locking capabilities along the auditory hierarchy, we hypothesized that FFRs to higher frequencies would receive less cortical contribution than those to lower frequencies, hence supp…

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…

Kā veicināt atturību studentu vidū: vienas organizācijas un vairāku morāļu gadījums

2019

Izmantojot morāles antropoloģijas pieeju un sekojot Aristotelim un Fuko, es pētu veidus, kā studentu organizācija veicina atturību no alkohola. Balstoties feminisma pieejā, izmantojot līdzdalīgo novērojumu un padziļinātas intervijas, es parādu, kā organizācijas biedri interpretē un ievieš skaidra dzīvesveida popularizēšanu studentu vidū. Tieša popularizēšana šķita neiespējama viņu minoritātes statusa dēļ, kā arī tādēļ, ka tā bija pretrunā ar viņu izpratni par izvēles brīvību. Atturību veicina, rādot piemēru ārpus organizācijas esošajiem, un atbalsta, izmantojot līdzvērošanu (sousveillance) starp tās biedriem. To nodrošina punktiņu sistēma, kas, sākotnēji iecerēta kā audita sistēma, praksē l…

Brain responses to sound intensity changes dissociate depressed participants and healthy controls.

2017

Depression is associated with bias in emotional information processing, but less is known about the processing of neutral sensory stimuli. Of particular interest is processing of sound intensity which is suggested to indicate central serotonergic function. We tested weather event-related brain potentials (ERPs) to occasional changes in sound intensity can dissociate first-episode depressed, recurrent depressed and healthy control participants. The first-episode depressed showed larger N1 amplitude to deviant sounds compared to recurrent depression group and control participants. In addition, both depression groups, but not the control group, showed larger N1 amplitude to deviant than standa…

Auditory event-related potentials in separating patients with depressive disorders and non-depressed controls: A narrative review

2021

This narrative review brings together the findings regarding the differences in the auditory event-related potentials (ERPs) between patients with depressive disorder and non-depressed control subjects. These studies' results can inform us of the possible alterations in sensory-cognitive processing in depressive disorders and the potential of using these ERPs in clinical applications. Auditory P3, mismatch negativity (MMN) and loudness dependence of auditory evoked potentials (LDAEP) were the subjects of the investigation. A search in PubMed yielded 84 studies. The findings of the reviewed studies were not highly consistent, but some patterns could be identified. For auditory P3b, the commo…

Event-Related Potentials to Changes in Sound Intensity Demonstrate Alterations in Brain Function Related to Depression and Aging

2020

Measures of the brain’s automatic electrophysiological responses to sounds represent a potential tool for identifying age- and depression-related neural markers. However, these markers have rarely been studied related to aging and depression within one study. Here, we investigated auditory event-related potentials (ERPs) in the brain that may show different alterations related to aging and depression. We used an oddball condition employing changes in sound intensity to investigate: (i) sound intensity dependence; (ii) sensory gating; and (iii) change detection, all within a single paradigm. The ERPs of younger (18–40 years) and older (62–80 years) depressed female participants and age-match…

Pitkäaikainen kipu ja depressio : yhteyttä säätelevät tekijät

2004

Patrik Kuusinen tutki väitöskirjassaan Kelan maksamassa laitoskuntoutuksessa olleiden tuki- ja liikuntaelinten kivuista pitkään kärsineiden kokemusta kipuongelmastaan, itsestään ihmisenä ja tulevaisuudestaan sekä näiden käsitysten yhteyttä masennusoireisiin. Useimmilla potilailla niska- ja selkäkivut olivat kestäneet jo vuosia ilman mitään merkittävää helpottumista. The purpose of this study was to explore the relationship between chronic pain and depression. It was assumed that depression is a secondary reaction to pain and is mediated by how the patient perceives his/her life control and pain-induced personal interference and social interactions. These assumptions, derived from the mediat…

Inflammatory proteomics profiling for prediction of incident atrial fibrillation

2023

ObjectiveAtrial fibrillation (AF) has emerged as a common condition in older adults. Cardiovascular risk factors only explain about 50% of AF cases. Inflammatory biomarkers may help close this gap as inflammation can alter atrial electrophysiology and structure. This study aimed to determine a cytokine biomarker profile for this condition in the community using a proteomics approach.MethodsThis study uses cytokine proteomics in participants of the Finnish population-based FINRISK cohort studies 1997/2002. Risk models for 46 cytokines were developed to predict incident AF using Cox regressions. Furthermore, the association of participants’ C reactive protein (CRP) and N-terminal pro B-type n…

The Role of e-Tutor Competencies in Postgraduate e-Learning Courses: Spotlight on Emotion Management

2021

The role of e-learning in the existing and challenging educational era is crucial. However, it is necessary to overcome some drawbacks such as feelings of isolation and a lack of emotional contact. In this sense, emotion management is a key driver of student satisfaction in e-learning, which is significantly related to students’ motivation, learning, cognitive strategies, self-regulation, and personality antecedents in the classroom. This article examines an online postgraduate course in financial statements auditing, describing the resources used by the e-tutor to conduct affective tutorials, reduce students’ feelings of isolation, increase student involvement, and achieve success in e-lea…
