Event-related EEG analysis#
Estimated reading time:2 minutes
Load real visual and auditory oddball recordings through EEGDashDataset. Inspect actual annotations, define event-locked epochs and compare measured responses. The visual example evaluates a classifier on held-out subjects; the auditory example inspects one recorded run. The studies differ in more than stimulus modality, so their comparison is descriptive, not controlled.
plot_20_visual_p300_oddball.py: three visual recordings, about 69 MB.plot_21_auditory_oddball.py: one auditory run, about 63.4 MB.
Keep EEGDASH_CACHE_DIR between runs. Neither example prescribes an ERP amplitude or substitutes reference values for the measured result.
