Driven shield for multi-barrel electrode.
A driven shield for a nine-barrel micropipette containing a carbon fiber recording electrode in the center barrel is described. Two of the nine surrounding micropipettes were used as a driven shield channel to reduce capacitance between the recording electrode and the brain tissue. This method facilitates recording of single neuron activity, even in deep areas of the monkey brain, such as the amygdala and lateral hypothalamic area.
