The device comprises microfilaments of various materials and forms embedded within a body. The microfilaments form interaction sites with surrounding neural tissue at their exit points from the implantable body. The body and filaments are configurable in a multitude of positions to provide increased engagement of a given neural tissue section as well as interaction and closed loop feedback between the microfilament sites. Such configurations allow for a range of recording, stimulating, and treatment modalities for the device within research and clinical settings. ## Claims ### Claim 1 A neural microarray, comprising: a base member comprising an opening configured for engagement of an insertion tool, wherein the base member comprises a hinged portion;
