An improved probing device includes: an elongated, substantially cylindrical flexible fiber having a non-conducting outer surface; one or more circuits disposed on the outer surface of the fiber for simultaneously providing an electrical signal path to and from a plurality of locations, each of the circuits comprising a non-planar integrated circuit extending lengthwise along the outer surface of the fiber; and an insulating layer substantially disposed over the electrical circuits and around the outer surface of the fiber, the insulating layer having a plurality of openings through which selected portions of the electrical circuits are exposed to the locations. Such a probing device when adapted as a neural probe is especially useful for conducting deep brain measurement and stimulation.
