Methods of locating an optimal site within a brain of a patient for deep brain stimulation include positioning a guiding cannula in a lumen of a main cannula, passing a microelectrode through a lumen of the guiding cannula into the brain, adjusting an insertion depth and a longitudinal angle of the guiding cannula such that the microelectrode locates the optimal site for the deep brain stimulation, and passing a distal end of a macroelectrode or a deep brain stimulation lead through the lumen of the main cannula and into the brain at the optimal site.
