Information processing in the brain is distributed across large populations of neurons. Multielectrode recordings are one approach to read the population code especially when behavior is required. Multielectrode Arrays (MEAs) are a convenient way of bundling a large number of electrodes (>100) and are available from a number of companies. However, MEAs are usually put at a fixed depth, thus loosing the possibility to adapt the position during later recordings to improve isolation or sample different layers.
The EDDS Array Drive allows to move the entire MEA in depth. The MEA is fixed to a movable shuttle, which is mechanically restricted to precise depth movements only.
