This high-density EEG dataset comprises resting-state and task-based recordings from 23 healthy volunteers performing visual naming and spelling tasks. Collected between 2012-2013 at Rennes University Hospital using a 256-electrode EEG system, the dataset enables investigation of dynamic functional brain network reorganization during language production and cognitive processing. The study provides insights into spatiotemporal patterns of brain connectivity during object naming and orthographic tasks.

This dataset contains raw EEG recordings from participants performing a Braille letter discrimination task, in which Braille letters were presented to the left and right index fingers via Braille cells. The data were collected to investigate the transformation of sensory to perceptual representations of Braille letters in the visually deprived brain. Recordings were made using BrainVision hardware and are organized following the BIDS-EEG standard. For some participants, EEG recording was stopped and restarted within a session, resulting in separate runs, and some participants completed a second session.
