Dynamic Neural Compensation for Distorted Orientation Perception in Chronic Astigmatism

Each dataset contains EEG recordings from a single subject, along with the corresponding condition and stimulus information.(Note, if the subject belongs to the chronic astigmatism group, the filename ends with "chronic". If the subject belongs to the induced astigmatism group, the filename ends with "induced")Each dataset includes the following three structures:1. data.eeg - A 3D matrix of shape (number of electrodes) × (number of time points) × (number of trials). - All time series are aligned so that the stimulus onset occurs at the 101st time point. - Each time point indicates 1 ms (i.e. -99 ms to 525 ms relative to the stimulus onset)2. data.astig - A 1 × (number of trials) vector. - Each element is either 1 or 2, indicating the visual condition: • 1 = astigmatic vision condition • 2 = emmetropic vision condition3. data.ori - A 1 × (number of trials) vector. - Each element is an integer from 1 to 8, indicating the orientation of the visual stimulus. • 1 = 90° counterclockwise from the astigmatic axis • 2 = 67.5° • 3 = 45° • ... • 8 = –67.5°
