Emne: [Eeglablist] Question regarding color interpretation

Dear EEGLAB users,

I have a question regarding the scalp map color bar. I have read the following webpage:


Based on my understanding, red and blue both indicate activation, but opposite polarity. My question is, if there's an event that results in one side of the brain having red readings while the other side has blue readings, how would this data be interpreted?
