Detrending Moving Average, Power Spectral Density, and Coherence: Three EEG-Based Methods to Assess Emotion Irradiation during Facial Perception

چکیده
Understanding brain reactions to facial expressions can help in explaining emotion-processing and memory mechanisms. The purpose of this research is examine the dynamics electrical activity caused by visual emotional stimuli. focus on detecting changes cognitive mechanisms produced negative, positive, neutral human faces. Three methods were used study reactions: power spectral density, detrending moving average (DMA), coherence analysis. Using electroencephalogram (EEG) recordings from 48 subjects while presenting image stimuli International Affective Picture System, topographic representation evoked responses was acquired evaluated disclose specific EEG-based patterns cortex. theta beta systems are two key that activated differently basis gender. obtained results also demonstrate DMA method provide information about cortical networks’ functioning stability, so it be coupled with more prevalent EEG

EEG-based emotion perception during music listening
In the present study correlations between electroencephalographic (EEG) activity and emotional responses during music listening were investigated. Carefully selected musical excerpts of classical music tested in previous studies were employed as stimuli. During the experiments EEG activity was recorded in different regions without a-priori defining regions of interest. The analysis of the data ...
متن کاملDetrending moving average algorithm for multifractals.
The detrending moving average (DMA) algorithm is a widely used technique to quantify the long-term correlations of nonstationary time series and the long-range correlations of fractal surfaces, which contains a parameter θ determining the position of the detrending window. We develop multifractal detrending moving average (MFDMA) algorithms for the analysis of one-dimensional multifractal measu...

This electroencephalographic (EEG) study was designed to explore the differences in power spectra and coherence associated with subjective levels of engrossment, or absorption, in an auditory task. Quantitative referential EEG activity was recorded using 19 electrodes while subjects (n = 17) listened to a story and indicated on a continuous basis, by means of a hand held switch, whether they we...
