Tissue slices of the left and right hemispheres

Caption

Tissue slices of the left and right hemispheres showing two electrode insertions to (a) an off- target portion of the brain’s right hemisphere (using CARS), and (b) to the subthalamic nucleus (STN) of the brain’s left hemisphere (using DRS). Tissue types were visually identified from histological slices (HISTO) to generate a barcode composed of black (gray matter) and white (white matter) regions. This barcode is compared to the data acquired with the optical probe and analyzed using a PCA agorithm (PROBE barcode).
