DBS: Microelectrode Recording

Strip recording of electrical interference
Microelectrode Recording Screen
Sometimes a recording microelectrode is placed down the trajectory path before placing the stimulating electrode. The target nucleus can be "mapped" by "listening" to the different brain cells, hearing their different sounds and observing their different wave patterns. When the optimal location is found, the microelectrode is removed and replaced with the Deep Brain Stimulator Electrode.
