Somatosensory Deviance Detection ERPs and Their Relationship to Analogous Auditory ERPs and Interoceptive Accuracy
2022
Abstract. Automatic deviance detection has been widely explored in terms of mismatch responses (mismatch negativity or mismatch response) and P3a components of event-related potentials (ERPs) under a predictive coding framework; however, the somatosensory mismatch response has been investigated less often regarding the different types of changes than its auditory counterpart. It is not known whether the deviance detection responses from different modalities correlate, reflecting a general prediction error mechanism of the central nervous system. Furthermore, interoceptive functions have been associated with predictive coding theory, but whether interoceptive accuracy correlates with devian…
Effects of bioheapleaching technology utilizing metal mine emissions on fish in boreal freshwaters
2018
Emissions from metal mining activities are known to deteriorate the quality of aquatic habitats and impair the condition and reproductive potential of fish. Metal extraction by biomining methods has been considered to cause fewer emissions, but for example in Finland, the impacts of a bioheapleaching technology utilizing metal mine on the local freshwaters have been substantial. In this thesis, the impacts of the bioheapleaching mine emissions on three native fish species, brown trout (Salmo trutta) European perch (Perca fluviatilis) and whitefish (Coregonus lavaretus pallasi), were investigated. Manganese and sulphate concentrations have been elevated in the mining impacted waters, and in …

Removing ocular artifacts from magnetoencephalographic data on naturalistic reading of continuous texts
2022
Naturalistic reading paradigms and stimuli consisting of long continuous texts are essential for characterizing the cortical basis of reading. Due to the highly dynamic nature of the reading process, electrophysiological brain imaging methods with high spatial and temporal resolution, such as magnetoencephalography (MEG), are ideal for tracking them. However, as electrophysiological recordings are sensitive to electromagnetic artifacts, data recorded during naturalistic reading is confounded by ocular artifacts. In this study, we evaluate two different pipelines for removing ocular artifacts from MEG data collected during continuous, naturalistic reading, with the focus on saccades and blin…
Taking Familiar Others’ Perspectives to Regulate Our Own Emotion: An Event-Related Potential Study
2019
Current research on emotion regulation has mainly focused on Gross’s cognitive strategies for regulating negative emotion; however, little attention has been paid to whether social cognitive processes can be used to regulate both positive and negative emotions. We considered perspective-taking as an aspect of social cognition, and investigated whether it would affect one’s own emotional response. The present study used a block paradigm and event-related potential (ERP) technology to explore this question. A 3 (perspective: self vs. pessimistic familiar other vs. optimistic familiar other) × 3 (valence: positive vs. neutral vs. negative) within-group design was employed. Thirty-six college s…
"AIK var starkt eller starka?" : böjning av predikativ med egennamn, kollektiva substantiv och kvantitativa ord som subjekt
2015
Tutkimukseni tavoitteena oli tutkia, kuinka erisnimet, kollektiiviset substantiivit ja kvantitatiiviset sanat taipuvat kongruenssissa ja onko olemassa yhdenmukaisuutta tai sääntöä taivutuksessa ryhmien sisällä ja/tai välillä. Tutkin myös ruotsinruotsin ja suomenruotsin eroa taivutuksessa. Valitsin jokaista sanaryhmää kohden neljä sanaa muutamin poikkeuksin, joita etsin Korpen/Språkbanken tietokannoista. Valitsin ruotsalaisen sekä suomenruotsalaisen lehtien tietokannat ja etsin niistä predikatiivilauseita, joissa esiintyy kongruenssitaivuttamista. Jokaista sanaa kohden etsin kymmenen lausetta, mikäli tietokannasta löytyi niin paljon. Kokosin taulukkoihin, kuinka monta en-, ett- ja monikollis…

Therapeutic Benefits of Music-Based Synchronous Finger Tapping In Parkinson’s Disease – an fNIRS Study Protocol for Randomized Controlled Trial in Da…
2020
Abstract Background: Music therapy improves neuronal activity and connectivity of healthy persons and patients with clinical symptoms of neurological diseases like Parkinson’s disease, Alzheimer’s Disease, and Major Depression. Despite the plethora of publications that have reported the positive effects of music interventions, little is known about how music improves neuronal activity and connectivity in afflicted patients.Methods: For patients suffering from Parkinson’s disease (PD), we propose a daily 25-minute music-based synchronous finger tapping (SFT) intervention for 8-weeks. Eligible participants with PD are split into two groups: an intervention group and a control arm. In addition…
Cortical networks show characteristic recruitment patterns after somatosensory stimulation by pneumatically evoked repetitive hand movements in newbo…
2022
Abstract Controlled assessment of functional cortical networks is an unmet need in the clinical research of noncooperative subjects, such as infants. We developed an automated, pneumatic stimulation method to actuate naturalistic movements of an infant’s hand, as well as an analysis pipeline for assessing the elicited electroencephalography (EEG) responses and related cortical networks. Twenty newborn infants with perinatal asphyxia were recruited, including 7 with mild-to-moderate hypoxic–ischemic encephalopathy (HIE). Statistically significant corticokinematic coherence (CKC) was observed between repetitive hand movements and EEG in all infants, peaking near the contralateral sensorimotor…
Relationship between physical activity, fitness and brain morphology in youth
2017
Yhä useammat tutkimukset ovat havainneet yhteyden fyysisen aktiivisuuden, fyysisen kunnon ja kognitiivisten kykyjen välillä, mutta tätä yhteyttä selittävät tekijät ja siihen liittyvät muutokset aivojen rakenteissa ovat vielä varsin epäselviä. Tässä tutkimuksessa oli tarkoitus selvittää, onko fyysisellä aktiivisuudella tai fyysisellä kunnolla yhteyttä aivojen rakenteeseen nuorilla. Tutkimuksen koehenkilöt olivat 35 suomalaista nuorta (14.14 ±0.71 vuotta, 23 tyttöä & 12 poikaa), otanta laajemmasta AFIS (Active, Fit and Smart) -tutkimusprojektista. Tutkimuksessa mitattiin fyysistä aktiivisuutta objektiivisilla kiihtyvyysanturimittareilla, fyysistä kuntoa lasten ja nuorten mittaamiseen tarkoite…
