Research project

High resolution guided imaging project in the treatment of Parkinson's disease

Project Description

Deep brain stimulation's effectiveness relies on the ability of the stimulating electrode to be properly placed within a specific target area of the brain. Optical guidance techniques that can increase the accuracy of the procedure, without causing any additional harm, are therefore of great interest.

We have designed optical fiber-based device that is small enough to be placed within commercially available DBS stimulating electrodes' hollow cores and that is capable of sensing biological information from the surrounding tissue, using low power white light. With this probe, we have shown the ability to distinguish white and grey matter during stereotactic DBS lead implantations on both ex-vivo non-human-primate intact heads, as well as on in-vivo non-human-primates. The in-vivo measurements allowed us to compare simultaneously acquired optical data and neuronal activity using microelectrode recordings.

We are in the process of further advancing the procedure using other optical modalities such as spontaneous and coherent Raman spectroscopy - capable of providing molecular composition of the tissue. The addition of these modalities should increase the resolution of our electrode localization and provide the surgeon with regional specificity of the DBS surgical targets. The end goal will be to deploy this technology during deep brain stimulation neurosurgery in humans, leading to an increase in the accuracy and therefore efficacy of the procedure.
