  "Description": "Combined SSVEP dataset with single stimulus location for two inputs.\n\n\nDataset summary:\n\n#Subj       8\n#Chan      32\n#Classes       4\n#Trials / class  varies\nTrials length     5 s\nFreq 1000 Hz\n#Sessions       1\n\n\nParticipants:\n\n- Population: healthy\n\n\nEquipment:\n\n- Amplifier: eego mylab (ANT Neuro)\n- Montage: standard_1005\n\n\nData Access:\n\n- DOI: 10.1111/ejn.15030\n- Data URL: https://zenodo.org/records/18873228\n- Repository: Zenodo\n\n\nExperimental Protocol:\n\n- Paradigm: ssvep\n- Task type: covert_attention\n- Feedback: none\n- Stimulus: overlapping SSVEP arrows (CRT 85 Hz)\n\nDataset from [1]_.\n\nThis dataset uses a one-to-two SSVEP paradigm where spatially overlapping\nstimuli are presented at the same location. Users attend to one of four\narrow directions (up, down, left, right), each flickering at a distinct\nfrequency derived from the 85 Hz CRT refresh rate.\n\n8 subjects are available across two experiments:\n\n- Experiment 1 (S01-S05): Scheme 1 (moving dot-formed arrows)\n- Experiment 2 (S06-S08): Scheme 2 (space-based attention) and\nScheme 3 (object-based attention)\n\nEEG was recorded at 1000 Hz with a 32-channel ANT Neuro system.\nEach trial consists of 500 ms fixation, 500 ms cue, and 5000 ms\nstimulation.\n\nWarnings\n--------\nThe Zenodo archive used by this adapter contains only 8 of the 20\nsubjects described in the paper. Subject numbering (S01-S08) is based\non alphabetical order of the original subject name prefixes.\n\nReferences\n----------\n.. [1] L. Wang, Z. Zhang, D. Han, Z. Zhang, Z. Liu, and W.
