Recordings of electrical activity in freely moving animal are fundamental to understand brain function in health and disease. Such recordings require a small-size, lightweight device that includes movable electrodes (microdrive) to record either a new set of neurons every day or the same set of neurons over time. Ideally, microdrives should be easy to implant, allowing precise and smooth displacement of electrodes
 
Neuroscientists use microdrivers with different arrays variations of micro-electrodes in order to tune interstation of electrodes and sample brain signals.
 
The Micro dirver is a microscrew-based electromechanical device, assembled on the animal's head.
There are various configurations of channels: 16CH, 32CH of microdrivers fitted for direct sampling or wireless based equipment.
