The implantation of chronic recording electrodes in the brain has been shown to be a valuable method for simultaneously recording from many neurons. However, precise placement of these electrodes, crucial for successful recording, is challenging if the target area is not on the brain surface. Here we present a stereotaxic implantation procedure to chronically implant bundles of recording electrodes into macaque cortical sulci, employing magnetic resonance (MR) imaging to determine stereotaxic coordinates of target location and sulcus orientation. Using this method in four animals, we recorded simultaneously the spiking activity and the local field potential from the parietal reach region (PRR), located in the medial bank of the intraparietal sulcus (IPS), while the animal performed a reach movement task. Fifty percent of all electrodes recorded spiking activity during the first 2 post-operative months, indicating their placement within cortical gray matter. Chronic neural activity was similar to standard single electrode recordings in PRR, as reported previously. These results indicate that this MR image-guided implantation technique can provide sufficient placement accuracy in cortical sulci and subcortical structures. Moreover, this technique may be useful for future cortical prosthesis applications in humans that require implants within sulci.
