A) blood oxygenation levels generated by large numbers of neurons.
B) glucose metabolism generated by large groups of neurons.
C) voltage generated by large groups of neurons.
D) voltage generated by single neurons.

Question

Quizplus · Accepted Answer

Electroencephalography (EEG) measures voltage changes generated by large groups of neurons. The electrodes placed on the scalp detect the electrical activity of many neurons firing together, creating a characteristic wave pattern. EEG is commonly used to study human brain function, diagnose conditions such as epilepsy, and monitor brain activity during surgeries.
