The Thomas Tetrode Micro Matrix is a small and lightweight microdrive system for electrode and tetrode recordings.

The worlds smallest and most lightweight single tetrode system

Description

The Thomas Tetrode Micro Matrix is a small and lightweight microdrive system for electrode and tetrode recordings. The system consists of a single miniaturized microdrive system, which is equipped with a single tetrode or single core microelectrode. A four channel preamplifier and a precision motor is integrated in the single drive system shown in figure 1.

The new microdrive system has a lot of advantages in contrast to competitors products: (1) Each tetrode/electrode is compley shielded against noise pickup from the environment; (2) The patented rubber tube drive does not cause any slick or free motion like cable or hydraulic or thread rod driven microdrive systems;  (3) Adaptation to different electrode travel distances for cortical or deep brain recordings; (4) Modular system; (5) Networkable software to control one recording setup with up to 16 tetrodes from different workstations by more than one neuroscientist; 
(6) System uses thin microelectrodes with high recording quality (e.g. Thomas electrodes or tetrodes); (7) Low price; (8) Relatively small size and weight; (9) Easy setup and many features more.

The Thomas Tetrode Micro Matrix is a very lightweight and flexible drive solution for Thomas microelectrodes and tetrodes. It is a modular microdrive concept. One can mount multiple of these drives simultaneously on a recording chamber like shown in figure 2 or just one drive like shown in figure 3.
