An event-related potential (ERP) is a detectable brain signal related to the occurrence of a stimulus, cognitive, or motor event. P300 wave is an ERP related to decision making in the brain. It can be detected with an EEG using a simple Oddball paradigm where a target observes a screen which alternates between the target (stimulus) and non-target images.
For our first experiment, we replicated the Oddball paradigm using sample code from Alexandre Barachant’s muse-lsl workshop. Our results show the presence of the P300 wave in the TP9 and TP10 electrodes located behind the ears on the Muse brain sensing headband.
