Nakanishi2015 – SSVEP Nakanishi 2015 dataset

A 12-class steady-state visual evoked potential (SSVEP) derivative dataset acquired from 9 healthy subjects using 8-channel EEG recorded at 256 Hz with joint frequency-phase modulation. This preprocessed dataset was derived from the original Nakanishi et al. 2015 study and contains bandpass-filtered (6-80 Hz) and downsampled data with a 135-ms latency delay applied to account for visual system delay. The dataset was used to benchmark canonical correlation analysis (CCA)-based methods for SSVEP detection in brain-computer interface applications, demonstrating that individual calibration data significantly improves classification performance compared to standard CCA approaches.
