The ________ is a device used to detect the electrical activity of a single nerve cell in the brain.
A) micromyograph
B) macroelectrode
C) electroencephalograph
D) microelectrode
E) microdialysis probe

Question

Quizplus · Accepted Answer

A micromyograph measures the electrical activity of muscle fibers, a macroelectrode is too large to detect the activity of a single nerve cell, an electroencephalograph measures the collective electrical activity of many neurons, and a microdialysis probe is used to measure levels of neurotransmitters. Therefore, the best answer is D) microelectrode, as it is specifically designed to detect the electrical activity of a single nerve cell in the brain.
