Objective. We aim to develop and evaluate an affective brain–computer music interface (aBCMI) for modulating the states of its users. Approach. An aBCMI is constructed detect a user's current state attempt modulate it in order achieve specific objectives (for example, making user calmer or happier) by playing which generated according target algorithmic composition system case-based reasoning system. The trained tested longitudinal study on population eight healthy participants, with each...
Objectives While neuropsychological effects of conventional antidepressants are well-documented, more research is needed for rapid-acting antidepressants. This study examines the esketamine on emotion processing and cognitive functioning, both acutely sub-chronically.
Social dysfunction is one of the most common signs major neuropsychiatric disorders. The Default Mode Network (DMN) crucially implicated in both psychopathology and social dysfunction, although transdiagnostic properties remains unknown. As part pan-European PRISM (Psychiatric Ratings using Intermediate Stratified Markers) project, we explored cross-disorder impact on DMN connectivity.We studied intrinsic functional connectivity relation to by applying Independent Component Analysis Dual...
The neural mechanisms of music listening and appreciation are not yet completely understood. Based on the apparent relationship between beats per minute (tempo) desire to move (for example feet tapping) induced while that it is hypothesised musical tempo may evoke movement related activity in brain. Participants instructed listen, without moving, a large range pieces spanning styles tempos during an electroencephalogram (EEG) experiment. Event-related desynchronisation (ERD) EEG observed...
Brain-computer music interfaces (BCMIs) may be used to modulate affective states, with applications in therapy, composition, and entertainment. However, for such systems work they need able reliably detect their user's current state. We present a method personalised state detection use BCMI. compare it population-based trained on 17 users demonstrate that is significantly (p <; 0.01) more accurate, average improvements accuracy of 10.2 percent valence 9.3 arousal. also hybrid BCMI (a...
Brain-computer music interfaces (BCMI) provide a method to modulate an individuals affective state via the selection or generation of according their current state. Potential applications such systems may include entertainment therapeutic applications. We outline proposed design for BCMI and seek automatically differentiating different induced states. Band-power features are explored use in identifying music-induced Additionally, linear discriminant analysis classifier support vector machine...
Background Social functioning is often impaired in schizophrenia (SZ) and Alzheimer’s disease (AD). However, commonalities differences social dysfunction among these patient groups remain elusive. Materials methods Using data from the PRISM study, behavioral (all subscales total score of Functioning Scale) affective (perceived disability loneliness) indicators were measured patients with SZ ( N = 56), probable AD 50) age-matched healthy controls (HC, 29 28). We examined to what extent...
Beat perception is fundamental to how we experience music, and yet the mechanism behind this spontaneous building of internal beat representation largely unknown. Existing findings support links between tempo (speed) enhancement electroencephalogram (EEG) activity at tempo-related frequencies, but there are no studies looking may affect underlying long-range interactions EEG different electrodes. The present study investigates these using recorded from 21 volunteers listening music stimuli...
Previous studies of change blindness have suggested a distinction between detection and localisation changes in visual scene. Using simple paradigm with an array coloured squares, the present study aimed to further investigate differences event-related potentials (ERPs) trials which participants could detect presence colour but not identify location (sense trials), versus those where both localise (localise trials). Individual performance were controlled for by adjusting difficulty task real...
An affectively driven music generation system is described and evaluated. The developed for the intended eventual use in human-computer interaction systems such as brain-computer interfaces. It evaluated its ability to induce changes a listeners affective state. affectively-driven algorithmic composition was used generate stimulus set covering 9 discrete sectors of 2-dimensional space by means 16 channel feedforward artificial neural network. This 90 short pieces with specific intentions, 10...
Affective algorithmic composition is a growing field that combines perceptually motivated affective computing strategies with novel music generation. This article presents work toward the development of one application. The long-term goal to develop responsive and adaptive system for inducing affect both controlled validated by biophysical measures. Literature documenting perceptual responses identifies variety musical features possible correlations, but evaluations these purposes inclusion...
The feedback mechanism used in a brain-computer interface (BCI) forms an integral part of the closed-loop learning process required for successful operation BCI. However, ultimate success BCI may be dependent upon modality used. This study explores use music tempo as and compares it to more commonly visual mechanism. Three different modalities are compared kinaesthetic motor imagery BCI: visual, auditory via tempo, combined modality. Visual is provided position, on y-axis, moving ball. In...
This paper presents the External Attention Vision Transformer (EAViT) model, a novel approach designed to enhance audio classification accuracy. As digital resources proliferate, demand for precise and efficient systems has intensified, driven by need improved recommendation user personalization in various applications, including music streaming platforms environmental sound recognition. Accurate is crucial organizing vast libraries into coherent categories, enabling users find interact with...
Abstract The presence of a change in visual scene can influence brain activity and behavior, even the absence full conscious report. It may be possible for us to sense that such has occurred, if we cannot specify exactly where or what it was. Despite existing evidence from electroencephalogram (EEG) eye-tracking data, is still unclear how this partial level awareness relates functional magnetic resonance imaging (fMRI) blood oxygen dependent (BOLD) activation. Using EEG, fMRI, blindness...
Soil erosion poses a significant environmental issue in Kundasang, Sabah, which is situated the highlands and recognized for its soil challenges. The natural forces of water gradually wear away topsoil fields, leading to erosion. This phenomenon often exacerbated by various triggering factors such as agricultural practices, deforestation, unsustainable development. region particularly noted temperate vegetable cultivation. study aimed spatially estimate potential loss or using Revised...
