[ recordings from participants performing three near-threshold visual detection tasks with varying cue validity conditions: a no-cue baseline task, a noninformative cue task (50% validity), and an informative cue task (100% validity). The study investigates the neural mechanisms underlying visual perception at detection threshold, with particular focus on prestimulus alpha-band activity and its relationship to perceptual performance.

This dataset contains 128-channel EEG recordings from 20 observers (19 included in final analysis) viewing object images at 3.33 Hz to investigate how contextual associations, perceptual attributes, and conceptual properties of objects are represented in neural activity. One participant was excluded due to a technical error in EEG recording. Time-resolved neural decoding was applied to disentangle these distinct representational dimensions from the EEG signals.

This dataset contains raw and processed EEG recordings from participants engaged in silent visual reading of word stimuli presented in naturalistic narrative contexts. The study investigates auditory representations of words during reading by recording neural activity while participants view unique and repeated story narratives. The dataset includes BrainVision format EEG files, event annotations with stimulus triggers, preprocessed signals organized by channel, and corresponding feature embeddings for word-level analysis.
