--------------------------------------------------------------------------- APPENDIX IMP1 - PROMOTION OF HUMAN IMPLANTATION BY NIH THIS TEXT WAS COPIED FROM THE ORIGINAL NIH/CNCT WEB SITE AT THIS ADDRESS: http://www.engin.umich.edu/center/cnct/orgind.html Center for Neural Communication Technology Organization The NIH NCRR requires that its Centers have several basic components: internal research projects, collaborative research projects, and service to external investigators in the form of distribution and training. The organization of the Center for Neural Communication Technology (CNCT) will be described here with links to more details on individual projects. The underlying goal for all of the work conducted by the CNCT is to make multichannel recording and stimulation devices available to researchers which will enable them to more efficiently communicate with the brain. Micromachined electrodes offer the potential to extend small ensemble studies to tissue volume studies consisting of dozens if not hundreds of cells. Internal Research Projects There are three internal research projects under the Center which are designed to enhance the capability of the base technology: Project 1, Extensions of Micromachined Microelectrode Technology: Extend the basic structure of the device to include fluid carrying channels for delivery of fluids to tissue volume, and/or to lesion at recording/stimulation site locations. Project 2, Biological Neural Networks: Develop techniques for data acquisition from and analysis of neural circuits in the volume surrounding arrays of recording devices. The direction which has been proposed for this project over the next grant period will be to study the relationships between the physical characteristics of the devices and the architecture of the neural tissue to rationalize the process of design and experimentally explore and model the deterioration of chronic implants over time to improve their behavior.
