Human EEG recordings from 20 participants viewing rapid sequences of overlaid oriented grating pairs while detecting a target grating of a specific orientation. Feature-based attention was manipulated by cueing one of two gratings by colour, and temporal expectation was manipulated by making stimulus onset timing predictable or unpredictable. The dataset supports investigation of the time-course of attention effects dissociated from temporal expectation and target-related processes.

OcularLDT is a neuroimaging dataset contributed by Brooks, Gwilliams, Gramfort, and Marantz and mirrored on NEMAR from OpenNeuro (ds002312). The name suggests a lexical decision task with ocular measurements, but the README gives no details about participants, stimuli, or recording modality.

Electroencephalography recordings from 50 participants viewing 22,248 images spanning 1,854 object concepts from the THINGS database. Images were shown in rapid serial visual presentation streams at 10 Hz while participants performed an orthogonal fixation colour change detection task. The dataset supports research on the temporal dynamics of object recognition and visual representation in the human brain.
EEG dataset from 19 participants performing a visual P300 speller-like paradigm to assess how visual stimulus properties affect evoked responses and classification accuracy. Each participant completed three sessions with conditions varying the number of stimuli (4 to 9) and the flash type (standard flash versus a superimposed yellow smiling cartoon face). Recordings comprise 382 files from eight electrodes sampled at 256 Hz, with markers encoding trial phases and activated symbols.

Stereo-EEG (sEEG) recordings from seven adult epilepsy patients undergoing extended-stay clinical monitoring at Stanford Hospital, collected during brief aversive air puffs to the eye and around a 40-minute ketamine infusion (0.5 mg/kg). This BIDS-iEEG derivative represents the NWB data released on DANDI (001347), downsampled to 200 Hz, with 30 twenty-minute recordings and 88-206 contacts per participant. The data support study of the brain-wide emergence of emotional responses to sensory experience and their modulation by a dissociative drug.
