This dataset comprises stereoelectroencephalography (sEEG) recordings from epilepsy patients undergoing monitoring for seizure activity at Oregon Health & Science University. During monitoring, patients were presented with auditory and visual numerical stimuli that were either symbolic (Arabic numerals and spoken numbers) or non-symbolic (dot arrays and beeps), enabling investigation of numerical cognition and its neural representations in intracranial recordings.

This dataset contains neuroimaging data from an experiment investigating the neural processing of numbers, letters, and false fonts presented as single items or strings. The study employs event-related experimental design with two runs, each utilizing distinct stimulus categories marked by specific trigger codes to enable precise temporal analysis of brain responses to different visual stimuli. Data were acquired using magnetoencephalography (MEG).
