Abstract

A simple method to produce multi-wire bundles by spinning is demonstrated, yielding nine recording sites. These so called "niotrodes" are then used in an acute experiment to record from several positions along trajectories into rat's basal ganglia. Niotrodes with an impedance in the range of 300kOhm@1kHz display the capability to record both single and multi unit activity and seem to be able to map a small volume in the brain with high density. A novel spike detection operator and further improvements towards a multi-multi-unit array are suggested.
