1. A method for manipulating a neural tissue comprising: placing a ferrule within a portion of a cranium or a neural tissue proximate the cranium, the ferrule comprising: a bottom portion having a dorsal surface and a ventral surface, the ventral surface of the bottom portion being adjacent the neural tissue; a holding area attached to the bottom portion adjacent the dorsal surface for retaining an implantable device therein, the holding area comprising: a wall portion attached to and extending upwardly from the dorsal surface of the bottom portion and disposed around a portion of the holding area, the wall portion having an outer surface and an inner surface; a shelf portion attached to the wall portion and extending inwardly from the inner surface of the wall portion, the shelf portion having a dorsal surface and a ventral surface, defining one or more apertures and coupling the bottom portion with the wall; a securing mechanism coupled with the wall portion and configured for removably securing the implantable device within the ferrule, wherein the implantable device, while being retained, is secured between the dorsal surface of the shelf portion, the inner surface of the wall portion, and the securing mechanism; and one or more modulators disposed on the bottom portion, the one or more modulators configured to be coupled to the implantable device while the holding area retains the implantable device therein; and performing a function using the one or more modulators on the neural tissue adjacent the one or more modulators.
