Oddball

Oddball turns one of neuroscience's best-known experiments into a short game you play while wearing a Muse EEG headband. Watch or listen for the rare "oddball" among frequent standard stimuli. Each time an oddball appears, your brain produces a P300: a positive brainwave about a third of a second later that reflects attention and the updating of what you expect. Oddball records your EEG, averages your responses and scores your P300 for you. THREE WAYS TO PLAY • Visual, Standard: a blue or red circle at the centre of the screen. • Visual, Jump: circles appear anywhere on the screen; tap each red circle, right on it. • Auditory: low and high tones through the phone speaker or wired headphones. YOUR RESULTS • P300 amplitude (µV) and latency (ms), scored the same way every session. • Your average waveforms for standards, oddballs and their difference. • Re-mark the peak yourself with a…
