Three Dimensional Conformal Microelectrode Array

We will design, fabricate and test a low cost three dimensional micro-electrode array which has twoindividually accessible electrodes. We have applied materials using laminar flex circuit technologya readily adaptable array which will readily conform to concave or convex cortical surfaces, will deneural signals ranging from low to high frequencies, will be effective for both stimulation and recowill he biocompatible and will be easily configured by the researcher to either large or small numbeusing the same physical device. Long term objectives of the program are to enable the production ofwhich can be easily and inexpensively purchased and then put together to form custom arrays which cacortical surface recordings. The first phase of the program is the testing of prototypes with measurbiocompatibility, electrical and structural characteristics. The second phase of the program will inrecordings over a wide range of neural signals from evoked potentials to single unit recordings. Wethe feasibility of human use in the neurosurgical suite for use in procedures involving resection ortissue. Other potential uses such as brain slice applications or use in tissue culture experimentatiThe array will prove useful to medical and research areas which utilize techniques in surface recordcerebral cortex.
