This dataset comprises electroencephalography recordings from 16 subjects viewing rapid serial visual presentations of gabor-like stimuli at two presentation rates (6.67 Hz and 20 Hz). Participants performed a concurrent fixation color change detection task while EEG data were acquired. The study investigates the dynamics of visual feature coding and neural mechanisms underlying perception and feature integration.

This dataset comprises open-eyes EEG recordings from 88 participants (36 with Alzheimer's disease, 23 with frontotemporal dementia, and 29 healthy controls) during photic stimulation at incremental frequencies (5-30 Hz). Recorded using a 19-channel scalp electrode montage according to the 10-20 system at 500 Hz sampling rate, the dataset complements a previously published eyes-closed resting-state EEG collection from the same cohort. Both raw and preprocessed versions are provided, with preprocessing including bandpass filtering, artifact subspace reconstruction, and independent component analysis.

This dataset contains EEG recordings from 14 healthy participants performing a covert attention task with real-time neurofeedback based on alpha power lateralization. The study investigates whether real-time EEG feedback on alpha power lateralization can lead to behavioral improvements in a covert attention task, employing a single-blinded crossover design comparing real versus sham feedback conditions across three recording sessions.

This dataset comprises electroencephalography (EEG) recordings from 13 participants performing semantic imagination and perception tasks across visual and auditory modalities. Participants were presented with stimuli from three semantically dissimilar categories (guitar, flower, penguin) in pictorial, orthographic, and auditory formats. The dataset includes raw, preprocessed, and epoched EEG data acquired using a 124-channel ANT-Neuro system, providing a resource for investigating neural correlates of semantic processing and cross-modal perception.

This dataset contains EEG recordings from 36 participants performing a visual discrimination task involving a tilt illusion. Participants judged the orientation of a central grating surrounded by an annular grating at ±30 degrees, which induces a perceptual bias. The study investigates the prestimulus EEG correlates of alpha oscillation power and phase on discrimination performance and the magnitude of the tilt illusion effect.
