Abstract-- Silicon neural prosthetic probes require reliable
sensing electrodes able to access deep cortical structures
without breakage. However, manufacturing limitations
have prevented a strong and biocompatible silicon
electrode array from reaching this goal. We here
demonstrate the first high-density, parylene-coated silicon
probe (1.2 cm long) with micro-fabricated electrodes that
is able to be inserted in vivo without failure. This work
also presents new experimental results for array shank
