Automatic and optimal placement of neural probes

This project is realized by Joseph SURESH, Etienne BURDET and TEO Chee Leong.

Micro-machined probes are extensively used to record impulses from various areas in the brain, and to develop neural interfaces to auditory, visual and neuromuscular prostheses. The probe has to rupture the pia matter to penetrate the underlying cortical layers. Currently the probe introduction is done in an ad-hoc manner that damages the cortical layers. Using a probe with integrated force/torque sensors mounted on a linear precision stage, this project will measure the stress and shear on the probe while penetrating the cortical layers, and investigate the related damage on the tissue. It will develop an automatic penetration procedure and devices for the probe causing minimal damage.
