““glued to the top of the head. On conscious trials only, an ample voltage wave sweeps through this region. It starts around 270 milliseconds and peaks anywhere between 350 and 500 milliseconds. This slow and massive event has been called the P3 wave (because it is the third large positive peak after a stimulus appears) or the P300 wave (because it often starts around 300 milliseconds).14 It is only a few microvolts in size, a million times smaller than an AA battery. However,””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The P300 wave is a brief, measurable brain signal occurring 300‑500 ms after a stimulus, indicating conscious processing despite its tiny amplitude.
In simple terms: P300 shows conscious brain response.
