    a fixation structure carried by the base structure and positionable at least one of (i) over an opening in the skull and (ii) within an opening in the skull; and

    wherein at least one surface of the fixation structure defines at least one channel in which an intracranial device is capable of being placed, and the fixation structure further includes at least one fixation feature to enable the intracranial device to be secured to the fixation device; and
