Although the EEG is able to detect electrical activity in the brain, it cannot reveal what is happening inside individual neurons. To see that activity, one would use a(n) __________
A) microelectrode.
B) functional MRI test.
C) SQUID test.
D) positron emission tomography (PET) scan.

Question

Quizplus · Accepted Answer

A microelectrode is a tiny electrode that can be inserted into the brain to measure the electrical activity of individual neurons. This is the only option given that is capable of detecting activity at the level of individual neurons. The other options are imaging techniques that provide different types of information about brain activity but do not directly measure electrical activity in neurons.
