An apparatus and method for performing neurological intervention may include a cylindrical body including a tapered threaded portion that screws into a pre-drilled hole in a subject. Additionally, the apparatus may include a connector having a probe lock-screw that is disposed on the cylindrical body, at an end opposite to the tapered threaded portion. The connector may further include an opening to receive a probe. The probe may be inserted into a subject via the apparatus, and a depth of insertion of the probe within the subject may be adjusted by the probe lock-screw.
