A driveable bundle of microwires for collecting single-unit data from freely-moving rats.

A technique is described for making a sturdy, driveable electrode array of ten fine wires. This moveable array is a modification of a stationary electrode [4]. It has a number of notable advantages over other electrodes designed for recording single-unit activity in freely-moving small mammals. With this electrode many single cells can be recorded in each animal, cells can be held for many days, and recording quality is very good.
