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.

A standard measure of brain function and includes measures of psychomotor and visual scanning.

A measure of cognitive processing and brain response speed. P300 slowing may signal changes in cognitive function with such factors as age, concussions, or poor cardiovascular fitness (e.g. arterial plaque).

A measure of cognitive attentional resources. Reduction in voltage may signal changes in cognitive function with such factors as age, concussions, or poor cardiovascular fitness (e.g. high blood pressure).

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.

Tipping of the scale beyond the target range and significant differences in Alpha power between the left-front and right-front of the brain has decreased efficiency with stress, anxiety, or low moods.

A measure of electrical muscle activity at jaw and neck locations. Elevated levels may suggest muscle tightness.

EEG P300 Voltage data is processed with various algorithms and is statistically analyzed, sometimes comparing values with “normative” database reference values. The processed EEG data is commonly converted into color maps of brain functioning called “Brain maps”.

A measure of the correlation between two channels as a function of frequency. It also provides information about functional connectivity between cortical regions, revealing possible cognitive impairment.​
