Claim 0:
1. A system comprising;
a brain interaction apparatus comprising:
a plurality of filaments;
a brain invasive launcher having a plurality of launching channels extending in a longitudinal direction between a proximal end and a distal end thereof, each launching channel being configured for holding one of the plurality of filaments moveably arranged therein; and
a steering tip affixed to a distal end thereof of at least one of the plurality of filaments, wherein the steering tip comprises a portion tapering in a longitudinal direction of the at least one of the plurality of filaments thereby narrowing toward a distal end of the steering tip, the tapered portion being rotationally asymmetrical about a longitudinal axis of the at least one of the plurality of filaments and configured for guiding the at least one of the plurality of filaments along a pre-set trajectory; and
a cranial anchor for the brain interaction apparatus, the cranial anchor being configured to be secured to a skull of a subject, the cranial anchor comprising
a proximal end forming an outer flange;
an elongated distal end for inserting into a skull aperture, wherein an axial lumen is provided, the axial lumen being tapered in a longitudinal direction of the cranial anchor and narrowing toward the distal end;
wherein the proximal end comprises at least one groove extending from the circumference of the outer flange toward a central axis of the cranial anchor, the at least one groove is configured for aligning, at the distal end of the cranial anchor, with at least one of the plurality of launching channels of the brain invasive launcher and for receiving and guiding the at least one of the plurality of filaments into the least one of the plurality of launching channels, and wherein the axial lumen is configured for receiving and guiding the brain invasive launcher, and wherein the axial lumen provides a pivot point for directing the brain invasive launcher.
