A) in vivo voltammetry.
B) patch clamp electrophysiology.
C) intracellular recording.
D) extracellular recording.

Question

The technique of patch clamp electrophysiology permits researchers to study the function of individual ion channels by measuring the flow of ions through single channels. This technique involves placing a small patch of membrane over a glass pipette and applying suction to create a high resistance seal between the pipette and the membrane, allowing for precise measurement of ion flow. In vivo voltammetry involves measuring changes in the electrical potential across a neuron or group of neurons in live tissue, while intracellular and extracellular recording involve measuring the electrical activity of neurons but do not allow for precise measurement of individual ion channels.
