E) microdialysis probes.

Question

Quizplus · Accepted Answer

To conduct recordings in a single cell, a researcher would use microelectrodes. Microelectrodes are very small electrodes, usually less than a micrometer in diameter, that can penetrate a single cell and record its electrical activity. Magnetic resonance imaging (A) and magnets (B) are not suitable for recording single-cell activity. Macroelectrodes (C) are too large to penetrate a single cell and are used to record activity from a group of cells. Microdialysis probes (E) are used to measure the concentration of neurotransmitters in the extracellular fluid, but not to record single-cell activity.
