This dataset provides simultaneous EEG and fNIRS recordings from 12 participants performing a silent naming task and three sensory-based imagery tasks (visual, auditory, tactile) on objects from the semantic categories of animals and tools. It supports research on semantic decoding and brain-computer interfacing. Stimulus images and example Python scripts for loading the data with MNE and MNE-BIDS are included.

This dataset contains non-invasive electrophysiological recordings from the human cervical spinal cord in 30 healthy young adults, collected to test whether temporal expectation influences initial sensory processing in the spinal cord. Participants received electric median nerve stimulation at the left wrist after an auditory cue, with the cue-stimulus interval either fixed at 1100 ms or varied randomly between 100 and 2100 ms. Participants silently counted rare double-stimulus trials (80 ms ISI) and reported the count at the end of each block.

EEG recordings from 10 healthy participants performing an online P300 row-column speller task with a 6x6 character matrix. The study compared two stimulus types, Famous Faces and Inverting, in combination with language models for online classification. Data were recorded from 32 channels at 256 Hz across two sessions per subject with three runs each, and are annotated with HED tags.

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.

EEG recordings from twenty participants who learned three temporal intervals (short, medium, long). Two randomly interleaved subtasks were used: a Production task, in which participants produced a target interval, and a Perception task, in which they judged whether a computer-generated interval was correct. Visual feedback (checkmark or x) followed both tasks. The dataset supports investigation of temporal scaling of human scalp-recorded potentials.
