microelectrode
Miniature electrical probe
A microelectrode is an extremely small electrode used to measure electrical activity in individual cells or tiny tissue regions.
Neuroscientists use microelectrodes to record signals from single neurons: The microelectrode detected firing patterns in the motor cortex.
They're essential tools in brain research, cardiac studies, and neurological device development.
