title: A stereotaxic system for independent coordinated positioning of two or three microelectrodes.
abstract: This paper describes a straightforward, easily built and relatively inexpensive stereotaxic system that permits independent coordinated positioning of 2 or 3 microelectrodes. This system is ideally suited for situations where the ability to routinely place one electrode at a precise position relative to another is important. Resolution of relative position and interelectrode distance is +/- 50 micrometers. This system should prove useful for the study of local interactions in such neural aggregates as nuclei, motoneuron pools and within and between cortical columns.
