1. A very small electrode, typically used in scientific research to measure electrical activity in cells or tissues with high spatial precision.
Usage: technical; commonly used in neuroscience and physiology

Examples

• The researcher inserted a microelectrode into the neuron to record its electrical signals.
• Microelectrodes allow scientists to study the activity of individual brain cells.
• The microelectrode was positioned with a micromanipulator to ensure precise placement.
• Using microelectrodes, the team measured voltage changes across the cell membrane.
• The laboratory invested in advanced microelectrode technology for their neuroscience experiments.
