Scalp EEG recordings from 36 healthy university students during eyes-closed rest and a serial-subtraction mental arithmetic task. The dataset supports study of EEG correlates of cognitive workload and mathematical cognition, with applications in mental workload assessment and brain-computer interfaces. Participants were split post hoc into good and bad counters based on the number of completed subtractions. This BIDS version was converted from the PhysioNet release.

A collection of electroencephalography (EEG) recordings from 15 students (8 male, 7 female, aged 21-23) performing essay-writing tasks. The task was designed to assess cognitive conditions such as creativity, memory, and critical thinking under different generative AI interaction conditions. The dataset supports studies of brain connectivity during student learning processes with Gen-AI.

This dataset provides high-density (128-channel) EEG and mouse-tracking data from 31 adults aged 18-33, collected in 2020. It includes resting-state recordings and task recordings from food preference choices and semantic judgments. The resource is intended for studying the dynamic decision processes underlying binary choices in the human brain.

Electrocorticography (ECoG) recordings from 20 C57BL/6 mice in three cohorts: blinking light only, transcranial diagnostic ultrasound (tDUS) only, and combined tDUS with light. The dataset was collected to test how tDUS modulates the visual cortex's response to external visual stimulation. It includes raw, event-triggered, and processed ECoG data.

Preprocessed stereotactic EEG (SEEG) high-gamma power (50-100 Hz) from 16 patients with pharmaco-resistant epilepsy performing a probabilistic instrumental learning task with reward and punishment conditions. Data cover 248 bipolar derivations in the anterior insula, dorsolateral prefrontal cortex, lateral orbitofrontal cortex and ventromedial prefrontal cortex, time-locked to outcome. The derivative release supports information-theoretic analyses showing dissociable reward and punishment subsystems in the human frontal cortex.

A multi-session, multi-task EEG dataset for passive brain-computer interface research, collected from 15 healthy participants across two sessions. Recordings include resting state and three difficulty levels (easy, medium, difficult) of the MATB-II multitasking environment, recorded with 62 active electrodes at 500 Hz. The dataset supports cross-session and cross-subject mental workload estimation and neuroergonomics applications.

This dataset contains synchronized EEG, ECG and pupil recordings from 36 young and 39 older adults performing auditory cued reaction time tasks, plus a passive listening condition. The active tasks were a cued simple reaction time task and a cued go/no-go task, and they allow investigation of age-related differences in cortical, autonomic and pupillary responses during anticipation and perceptual decision-making.

EEG recordings from 17 male participants performing a guided visual search task while simultaneously completing a binaurally presented auditory N-back task. The design includes a baseline condition in which the auditory stimuli were ignored, and dual-task conditions with N-back levels of 0, 1 and 2, which vary auditory working memory load. The dataset includes 64-channel BioSemi EEG with EOG and mastoid reference channels and is annotated with HED.

EEG recordings from fourteen healthy participants performing a covert spatial attention task across three sessions. The study tested real-time feedback of alpha power lateralization (α-LI) versus sham feedback in a single-blinded crossover design. It examined whether such neurofeedback leads to behavioral improvements in attention.
