(Physical. Reaction Time)
A measure of speed in response to an audible odd tone (distinct from brain reaction time, Audio P300 Delay Latency). This relies on different pathways than the P300 Delap, so physical reaction time may be different from your brain speed. This may decline with such factors as age, fatigue, or concussions.
(Theta/Beta Ratio at Cz)
Theta and Beta frequency bands are affected by cortical arousal and can give insight into how your brain functions. In some people, high theta beta ratios at Cz may present as inattention, while others may benefit from cortical arousal. Consult your physician if you have questions.
