Quirks of an EEG headset

The human brain is an incredibly complex organ, with potentially hundreds of thousands of neurons firing in response to different thoughts and stimuli. When measuring EEG it is important to use contrasting mental states to filter out noise. For example, if you were trying to capture an EEG response to visual stimuli, you may want to include a sampling run where the participant has their eyes closed. This provides you a baseline of EEG data that you know is not connected to the stimulus you are looking to analyze.

Here’s another example: in an experiment conducted by [REFERENCE], the
