The CrossModal Study is an EEG dataset investigating how the brain prepares for and discriminates targets across sensory modalities. Participants received cues to prepare for auditory, visual, or non-specific targets, followed by a 3-second interval with frequency-tagged visual stimulation (36 Hz) and amplitude-modulated auditory stimulation (40 Hz). Targets were either Gabor patches or tones, with cross-modal distractors presented in cued conditions. The dataset comprises 28 experimental blocks per participant and includes EOG recordings to monitor eye activity.

This dataset comprises electroencephalography (EEG) recordings from 40 participants performing a two-door decision-making task with monetary feedback. Participants completed 20 blocks of 20 trials each, alternating between learnable blocks where one door had a 60% win probability and the other a 10% win probability, and unlearnable blocks where outcomes were randomized. Post-block surveys assessed subjective perceptions of door quality, enjoyment, motivation, and performance. The dataset enables investigation of neural correlates of learning, decision-making, and feedback processing under conditions of varying environmental predictability.

This dataset comprises magnetoencephalography (MEG) recordings from 23 participants viewing 40 validated emotional video stimuli, complemented by a large-scale behavioral survey (500 participants) and head digitization data. The dataset provides multi-faceted emotion annotations including Self-Assessment Manikin (SAM) ratings for valence and arousal, discrete emotion categories (PrEmo), and temporal scene selections, enabling investigation of emotion-specific neural signal patterns for brain signal-based emotion recognition research.

This dataset comprises resting-state and loudness dependence of auditory evoked potentials (LDAEP) EEG recordings from 69 healthy women (ages 19-40 years) acquired at the University of Oslo. The study investigates the relationship between hormonal contraceptive use and central serotonergic activity indexed by LDAEP. Data include 64-channel EEG recordings at 2048 Hz sampling rate, alongside comprehensive phenotypic data on hormonal contraceptive use, menstrual cycle phase, depressive symptoms, impulsivity, and lifestyle factors.

This dataset comprises resting-state EEG recordings from 51 right-handed undergraduate participants collected to investigate the relationship between resting-state EEG alpha/theta power, oscillatory dynamics, and trait anxiety. Participants completed a 4-minute alternating eyes-open and eyes-closed protocol while 256-channel EEG was recorded at 500 Hz. The dataset includes raw EEG data and phenotypic measures from standardized anxiety and personality questionnaires (STAI, TIPI, BIS/FFFS).

The EPOC dataset comprises electroencephalography (EEG) recordings and cognitive/behavioral assessments from 98 participants recruited from the COVIDOM/NAPKON-POP longitudinal study to investigate neurophysiological correlates of post-COVID-19 syndrome. Participants completed a single laboratory session including the Trail Making Test, a battery of computerized cognitive tasks (n-back, psychomotor vigilance task, Montreal Cognitive Assessment), resting-state EEG recording, and self-report questionnaires assessing fatigue, anxiety, depression, and sleep quality. The study stratified participants based on self-reported cognitive symptoms to examine potential neurophysiological differences associated with post-COVID-19 symptomatology.

This dataset comprises 128-channel EEG recordings acquired during speech production tasks involving overt, minimally overt, and covert speech conditions. Participants produced one of five color words with each trial consisting of five repetitions. The dataset includes calibration and online real-time decoding sessions, along with supplementary physiological recordings (EOG, EMG, microphone) and trigger markers, designed to investigate neural contributions to EEG-based speech decoding.
