Single-unit recording requires:
A)A cannula
B)A microelectrode
C)An array of electrodes
D)None of the above

Question

Quizplus · Accepted Answer

Single-unit recording involves recording the electrical activity of a single neuron, and this requires a microelectrode, which is a small, thin electrode that can be inserted into the brain tissue to pick up the electrical signals emitted by individual neurons. Cannulas are typically used for infusing drugs or solutions into the brain tissue, while arrays of electrodes are used for recording the activity of multiple neurons simultaneously, neither of which are ideal for single-unit recording.
