1. Extremely small electrodes, typically measuring micrometers in diameter, used to measure electrical activity in cells or tissues or to stimulate neural activity.
Usage: technical; scientific; plural form of microelectrode

Examples

• Researchers implanted microelectrodes into the brain to record neural signals.
• The microelectrodes were small enough to measure activity from individual neurons.
• Scientists used microelectrodes to stimulate specific regions of the motor cortex.
• The array of microelectrodes allowed simultaneous recording from multiple cells.
• Microelectrodes have become essential tools in neuroscience research.
