Stereoelectroencephalography (sEEG) recordings from epilepsy patients at Oregon Health & Science University, collected while they were in the epilepsy monitoring unit awaiting seizures. Participants were presented with auditory and visual numerical stimuli, either symbolic (Arabic numerals and spoken numbers) or non-symbolic (dots and beeps). The dataset supports investigation of the neural representation of numerical quantity across modalities and formats.
This dataset contains multimodal recordings from 18 participants performing a mental arithmetic task across eight levels of difficulty, designed to study cognitive workload. It includes 19-channel EEG, ECG, and Pupil Labs eye-tracking (pupillometry) data synchronized via Lab Streaming Layer and converted to BIDS from XDF recordings. Task events encode difficulty ranges based on Q-values, with a 60-second baseline followed by 70 randomized questions.
[ 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.

EEG dataset from twelve participants who completed three reinforcement learning tasks that differed in average task value. In each task, participants learned cue-response mappings for six coloured-shape cues, using left or right key presses. Cues had feedback validity of 0.5 (low-value) or 0.8 (high-value), and the tasks contained only low-value cues, only high-value cues, or a mix of both. The dataset supports investigation of how task-level value affects trial-level reward processing.
