1. A method for manipulating a neural tissue comprising: placing a ferrule within a portion of the cranium or a neural tissue proximate the cranium, the ferrule including a bottom portion having a dorsal surface and a ventral surface, the ventral surface being adjacent the neural tissue, the ferrule further including a holding area attached to the bottom portion adjacent the dorsal surface for retaining an implantable device therein, and including 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 modulators on the neural tissue adjacent the one or more modulators.
