What is the name for an electrical wire so small that it can be used to monitor the electrical activity of a single neuron or to stimulate activity within it?
A) microelectrode
B) electrical probe
C) microelectronic probe
D) electroencephalograph

Question

Quizplus · Accepted Answer

A microelectrode is a very fine wire electrode that is used to monitor the electrical activity of a single neuron or to stimulate activity within it. It is commonly used in neuroscience research to study the function of the nervous system at a cellular level. The other answer choices are not specific enough for this application. An electrical probe could refer to any type of device used to measure or manipulate electrical signals, while a microelectronic probe suggests a device that incorporates electronic components, which is not necessarily the case for a microelectrode. An electroencephalograph (EEG) is a different type of tool used to measure electrical activity in the brain, but it does not have the same level of spatial resolution as a microelectrode.
