EEG recordings from participants performing two reversal learning tasks that differ in reinforcer type: monetary reward versus avoidance of an aversive loud white noise burst. In the reward task, positive feedback meant a gain of 10 cents and negative feedback meant no gain. In the punishment task, positive feedback meant the noise burst was successfully avoided and negative feedback meant the noise was delivered. Noise intensity was titrated per participant to match the motivational value of the 10 cent reward.

EEG dataset from a cross-modal cueing study in which participants were cued to prepare for an auditory, visual, or non-specific target. A 3-second task-irrelevant delay followed the cue, during which a fixation cross was frequency-tagged at 36 Hz and a 40 Hz amplitude-modulated tone was played. Participants discriminated one of three gabor-patch or tone targets, sometimes with a distractor from the uncued modality. The dataset supports investigation of alpha oscillations and target preparation in cross-modal attention.

This dataset contains simultaneous electroencephalography (EEG) and electroglottography (EGG) recordings with audio collected during speech production under delayed auditory feedback. The audio channel holds the delayed feedback heard by the participant, and the EGG signal was minimally preprocessed to correct phase delays introduced by the amplifier hardware filter. Per-trial delay values in the events sidecar allow the speech waveform to be realigned to the time of production.

EEG recordings from 21 participants performing an offline auditory spatial oddball task for a multi-class brain-computer interface (AMUSE). Five frontal speakers presented unique auditory stimuli under three conditions that varied inter-stimulus interval and speaker configuration, and participants attended to target directions. The data were used to evaluate P300-based spelling and communication paradigms, and are distributed here in preprocessed form through MOABB.

Functional near-infrared spectroscopy (fNIRS) recordings of human auditory cortex from participants with subjective tinnitus and matched controls. The dataset supports investigation of whether subjective tinnitus severity relates to objective hemodynamic changes in auditory cortex. Data were acquired with a NIRx NIRSport2 system and organized in BIDS format.

EEG recordings from 14 healthy participants performing a visual P300 oddball BCI task for controlling a Bluetooth speaker, one of several home appliances in the original study. The task used a 6-class flash-stimulus paradigm on an LCD display. Data were recorded from 31 channels at 500 Hz, with 50 training and 30 testing blocks per subject. The dataset supports research on ERP-based BCIs for home appliance control and inter-subject transfer learning.

EEG recordings from 146 participants (98 individuals with Parkinson's disease and 48 controls) performing a Simon conflict task. Stimuli appeared on the left or right side of the screen, and participants responded with a left or right key according to stimulus color. Trials were spatially congruent or incongruent with the response hand. Data were collected alongside other cognitive tasks to study conflict processing and midfrontal activity in Parkinson's disease.

This dataset contains 32-channel EEG recordings acquired during a sham neurofeedback experiment in a virtual reality environment. The study examined how feedback valence (positive, negative, or none) modulates alpha-band activity during an attentional task. Each participant completed positive, negative, control, and resting-state (eyes open/eyes closed) conditions.

EEG recordings from an auditory oddball task collected at the Meditation Research Institute in Rishikesh, India. Participants completed three sessions of a P300 paradigm with standard tones, oddball tones and white-noise distractors while sitting with their eyes closed in a darkened room. The dataset supports research on auditory event-related potentials and attention.
