Microelectrode

Broader Terms

In effect, when your microelectrode is measuring the potential of the inside of a neuron, you are actually measuring the potential difference across the neuron's membrane.
So an electrode is what one uses to deliver electric shock to the patient's head in electroshock therapy or to the patient's heart in the emergency room (that pair of iron-like things doctors hold when they are shouting, "Clear!") A glass microelectrode is used in our experiment.
The microelectrode is repeatedly moved in a programmable move-wait-measure routine (1,2 or 3D) and also grid or vector scanned or positioned with a 3D motorized, micro-stepping micro-manipulator.
When it is time for a microelectrode recording the stylet is removed and the microelectrode is inserted.
Each pass of the microelectrode is advanced in a stepwise fashion into the patient’s brain in order to obtain necessary information on the three dimensional location of the target.
