You want to record the activity of a group of neurons in the motor system to develop control of an artificial limb. Which of the following techniques would best measure this type of activity?
A) multi-unit recording procedures
B) a single-cell recording procedure
C) an MRI
D) a PET scanner

Question

Quizplus · Accepted Answer

Multi-unit recording procedures can capture the activity of a group of neurons simultaneously, which is important for understanding motor control for an artificial limb. Single-cell recording procedures are limited in their ability to capture the activity of multiple neurons at once. MRI and PET scanners are imaging techniques that are not capable of directly measuring neural activity but rather provide information about brain structure and function at a macroscopic level.
