•Beta-band power of EEG recorded over occipital sites is related to visual attention.•Older subjects could be divided into high and low performer (HP & LP) subgroups.•HPs did not differ from young subjects in terms of beta-band power changes.•Attentional depletion of LPs is revealed...
The EEG was online band-pass filtered between 0.1 and 100 Hz, and the data digitized with a sampling rate of 500 Hz. EEG pre-processing We used the Brain Vision Analyzer program (Version 2.1.0.327; Brain Products GmbH, Munich) to pre-process EEG data. Only the 200 s eyes-closed ...
EEG data were band-pass filtered with a passband frequency of 2 to 32 Hz. Audio preprocessing For both the stimulus reconstruction and binary classification methods, we pre-processed the two clean, audio streams to extract their broadband envelopes using the iterative algorithm in Horwitz-Martin ...
To be specific, on the basis of key frequency bands and channels selection, multi-channel band features are first extracted (using a multi-channel backbone network) and then fused (using attention units). In order to verify the performance, the proposed model is tested on an open-a...
alpha-frequency band resulting in 54 features per subsequence (18 electrodes à three frequency bands),interval recomposing: recomposing the interval from the subsequences.Time-frequency analysis: generating time-frequency maps (128 x 128 pixels) per electrode with Morlet wavelets,3D-image construction...
The dopamine system is associated with attention, short-term memory tasks, motivation, planning, and reward [40]. Therefore, cerebral effort increasing in the frontal lobe for artists may be related to differences in attention and motivation level or the performance of memory tasks during the ...
{w}_{2}\) are vectors that contain the transformation sub-band outputs concatenated, while \({\Lambda }_{1, j}\) and \({\Lambda }_{2, j}\) are the regularization parameters of lengths \({J}_{1}+1\) and \({J}_{2}+1\), respectively, associated with the two filtering ...
[69], specifically, the baseline was selected as the 500 ms prior to the stimulus. The data were recalculated individually based on the mean reference, and a band pass filter was applied in the frequency range 1 Hz–40 Hz. Then, an automatic precedence was applied to eliminate the trials...
we will explore new approaches to conduct more effective feature extraction for EEG signals. Potential methods include filtering the alpha band features of EEG signals, which has a strong inter-individual variance in the resting state; and selecting the channels with strong correlation to person ident...
