Electroencephalographic responses to the number of objects in partially occluded and uncovered scenes
EEG ZarrEEG recordings from 23 participants performing a passive viewing task with partially occluded and subsequently uncovered scenes containing game pieces on a game board. Conditions varied the number of initially visible pieces (4 or 32) and the number of pieces revealed after the occluder was removed (0 to 32). The dataset supports investigation of neural responses to object numerosity in occluded and uncovered visual scenes.

Cross-modal Oddball Task.
BEH EEG ZarrEEG dataset from 146 participants (98 with Parkinson's disease and 48 controls) performing a cross-modal oddball task collected between 2017 and 2021. Each trial presented simultaneous visual and auditory pre-cues, either standard or oddball, followed by a directional arrow GO cue requiring a response. The dataset supports investigation of midfrontal neural activity and cognitive dysfunction in Parkinson's disease.

Arithmetic calculations measured by intracranial EEG in the human brain
iEEGStereo-EEG recordings from 20 patients with pharmacoresistant epilepsy performing a sequential three-operand arithmetic task during presurgical evaluation. The deposit contains preprocessed, bipolar-referenced epochs (-2 to +7 s around the first operand, 512 Hz) from 1518 bipolar channels, with MNI contact coordinates. It supports analyses of the temporal order of activations and interactions in numerical cognition. It is released as a BIDS derivative of the authors' Zenodo deposit.

Auditory oddball comparison (Optimum-1, Learning-oddball, and the local–global paradigm)
EEG ZarrRaw EEG recordings from 15 participants who each completed three auditory oddball sequences: the Optimum-1 paradigm for mismatch negativity (MMN), a learning-oddball paradigm for P3b, and the local–global paradigm for local and global effects. The dataset supports comparison of within-individual sensitivity of MMN and P3b effects across specialized oddball sequences and the local–global paradigm. Corrected event files, stimulation sequence definitions and stimulus presentation code are included.

Reward gain and punishment avoidance reversal learning
EEG ZarrEEG 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.

IllusionGameEEG_data
BEH EEG ZarrThis dataset contains EEG, physiological (ECG, PPG, respiration) and behavioural recordings from 103 healthy adults aged 21-45, collected in 2022-2023 as part of a larger study. Participants completed an 8-minute eyes-closed resting state, followed by the Illusion Game. In this task they made perceptual judgements about the Ebbinghaus, Müller-Lyer and Vertical-Horizontal illusions, with task difficulty and illusion strength varied. The data are intended for investigating individual sensitivity to visual illusions as a general factor.
